- Dahlia is a green express engine. She pulls the express on the main-line, and despises trucks. Dahlia was vain, and refused to help Gordon and Henry on the main line. She gave advice to Diesel, and also refused to swap jobs with Henry; Dahlia was to take Henry's trucks, and Henry shunted coaches. She stopped at the brick bridge between Gordon's Hill and Wellsworth Station. Henry came to pulled Dahlia to Wellsworth Station. The Fat Controller scolded her for refusing to pull trains.

- Edwin is an powerful mixed-traffic LNER Gresley Class V3 tank engine. He was built in 1931, and rebuilt 1939. During the war, he was used for shunting trucks for the British Army. In 1946, he arrived on Sodor, and was withdrawn in 1959 when Sir Topham Hatt didn't have the funds to repair Edwin, so he locked him away in a shed in the forests. In 2008, Molly the yellow engine encountered him late at night and thought he was a ghost by his white paint and ghoulish steam he created. When she found out he wasn't a ghost, Sir Topham Hatt restored him and now he works on Thomas' branchline and the mainline, and is best friends with Thomas, Percy, Emily and Molly. Edwin is based on LNER Gresley Class V3. He is no. 19. He is painted NWR black. Edwin is voiced by Matt Wilkinson in UK, and William Hope in US.
- Vincent is a green 4-4-0 tender engine with red lining and a eight-wheel tender, resembling Edward. He is based on the London and South Western Railway 'T9' Class 4-4-0. Only one has survived into preservation which is No.120 (BR No.30120) currently based at the Bodmin and Wenford Railway in Cornwall, Southern England. By now, Vincent is probably working with Kenny on the Kirk Ronan branch line. He is voiced by Matt Wilkinson in UK, and William Hope in US.
- Bob is a blue 0-8-2 tank engine based on LNWR 1185 Class built in 1911 by the London and North Western Railway (LNWR), who looks like Thomas but bigger. By now, Bob is probably working at Tidmouth as a shunting engine, arranging all manner of rolling stock. As well as retaining his blue paintwork, Bob probably retains the sign-writing of "Croven's Gate Works" painted on his side tanks. Bob is voiced by Matt Wilkinson in UK, and William Hope in US.
- Kenny is a black 0-6-0 tender engine built in 1876 by L&YR (Lancashire and Yorkshire Railway) that looks like James, and he was looking sad when the Fat Controller came to the workshop to choose a new tank engine. Many years later, Kenny is probably now working on the Kirk Ronan branch line. Kenny is voiced by Matt Wilkinson in UK, and William Hope in US.
- Harley is a green 4-4-4 tank engine who works at the Kirk Ronan branch line. He is based on an NER Raven H1 4-4-4T. He is voiced by Matt Wilkinson in UK, and William Hope in US.

He is a modified Baldwin 2-4-2 with an extended rear cab, two domes and a bell at the front of his boiler. Stan is voiced by Matt Wilkinson in UK, and William Hope in US.
- Ten Cents is a small tank engine and the first Star fleet engine. He is one of the younger Star Tugs. He has a tendency to be somewhat cheeky at times, but he is strong willed and it takes a lot to break him. He is quick-witted and takes action swiftly without hesitation. He never lets other tugs bully him and never fails to stand up for others. He is always willing to set aside his own safety for the sake of others. His whistle/hooter's tone is strident but middle-pitched and Ten Cents almost always sounds it in a quick double-or-triple-bursts. He speaks with a strong East End Cockney accent. Ten Cents works mainly with Sunshine, the Star Fleet's third and smaller tank engine. They have shared many adventures, almost to the extent that it is impossible to imagine one without the other. Hercules often relies on Ten Cents to look after others such as Lillie or the Duchess. He is no. 1. He is based on LBSCR Billington E2-Class 0-6-0T. He is voiced by Simon Nash in UK, and Sam Gold in US.
- Big Mac is a large and powerful tender engine with a distinctively broad Glaswegian accent. Big Mac can come across a rude and stubborn engine, but he has a heart of gold, despite his tedencies to be macho, gruff and tough at times. He is very much willing to set aside his own safety for the sake of others, and usually (but not always) remains level-headed when undergoing a strategy. Big Mac works mainly with Warrior, an engine who resembles him in many ways. As opposed to his gruff personality, he is fitted with a rich and melodic chime whistle. Big Mac is without a doubt an essential character to engines, he is, after all, the strongest tug of the fleet and despite his sometimes abrasive manners, he can be kind and gentle. He is always willing to help out someone in trouble, and uses his great strength to help wherever he can. He is no. 2. He is based on BR standard class 9F goods engine. He is voiced by Nigel Anthony in UK, and Phil Lollar in US.
- OJ is a wise old tank engine with prominent single driving wheels and an Welsh accent. OJ's whistle is the deepest of the Star Engine's, and has a distinct 'warble' in it, sounding very much like a distress klaxon sounded for short bursts. As the Star Fleet's 'wise elder', OJ possesses unbeatable wisdom. He has extensive knowledge and experience of harbour life and manoeuvres, and because of this, Captain Star often places him in charge of large operations, such as ocean liner docking maneuvers. On various occasions, OJ has demonstrated his ability to devise swift and clever strategies to help himself and his fellow Stars out of predicaments. He does not stand for nonsense, and is quick to correct the younger tugs if they make mistakes. Despite his occasionally harsh approach, OJ cares for his brothers as a grandparent would for their grandchildren. He is no. 3. He is based on the North Eastern Railway's 2-2-4T. He is voiced by Timothy Bateson in UK, and Sam Gold in US.
- Top Hat is an arrogant and pompous express engine with a top hat, a monocle and a Upper Class (Posh English) accent. Like OJ, Top Hat's whistle is very deeply pitched, but softened somewhat in comparison with OJ's - he is also fitted with a fog-horn. Top Hat cares mainly about himself and saving his own neck. He is often ridiculed by his companions, particularly Ten Cents and the villanous Z stacks. He is no. 4. He is based on LNER Class A4. He is voiced by John Baddeley in UK, and Godfrey in US.
- Warrior is a strong but clumsy tender engine. He usually works with his close companion, friend and colleague Big Mac. Like Harvey, he speaks with a deep voice and a probably South London accent. Warrior's whistle has a single note and is very nasal, much like a factory hooter. He is no. 5. He is based on LNER B12. He is voiced by Sean Barrett in UK and US.
- Hercules is a railway-going, mysterious tender engine. Character-wise, Hercules is a cool-headed fighter. He speaks with a clear, soft tone and a politically correct (P.C.) English accent, but his words are often hard. Nothing can break him and not even the antics of the Z-Stacks and Bluenose can set him back. He is held in high regard by most of the tugs in the harbour, and even Zorran knows that he cannot win a confrontation with Hercules. Hercules is famously known for referring to his fellow Star Tugs as "ma' dears", "darling" and "sweet-heart". He has black sideburns on the side of his smokebox. He is recognised for his 'discreet' relationship with Lillie Lightship, and his 'lady's man' persona. Like Big Mac, Hercules is fitted with a chime whistle, but one with a 'cleaner' sound and a two-tone signiture. He is no. 6. He is based on LNER Class A3 4-6-2. He is voiced by Nigel Anthony in UK, and Godfrey in US.
- Sunshine is a small saddle tank engine and Ten's Cents' best friend. Sunshine can be occasionally cheeky at times, but he is very strong willed nevertheless. He is quick-witted and takes action swiftly without hesitation (usually). Sunshine also can figure things out very quickly. On the subject of whistles, Sunshine's is middle-to-high pitched and has a distinct 'whooping' sound which could best be described as 'upbeat', suiting his personality and name. Sunshine works mainly with Ten Cents, the Star Fleet's first and larger tank engine. They have shared many adventures, almost to the extent that it is impossible to imagine one without the other. Sunshine has a rather soft Newcastle (or Geordie) accent and (most of the time) he whistles when he speaks, because he is missing some of his front teeth. He is no. 7. He is based on GWR Avonside 0-4-0ST with No. 1430 "Trojan" body shape and 1361 Class bunker. He is voiced by Shaun Prendergast in UK, and William Hope in US.
- Grampus is a Star Fleet narrow gauge engine once owned by the navy. He is a close friend with the Star Fleet and has helped them out in various situations. He speaks with a Central English accent (with a noticeable lisp). He is no. 8. He is based on Talyllyn Railway's "Edward Thomas". He is voiced by Lee Cornes in UK, and William Hope in US.
- Lillie Lightengine is a friend of the Star Fleet and Ten Cents has a crush on her. She is voiced by Susan Sheridan.
- Sally Seadiesel is a friend of the Star Fleet and Sunshine has a crush on her. She is voiced by Cree Summer.
- Zorran is a very evil, scheming engine, rival to Ten Cents and the first Zero fleet engine. His lackeys are usually Zug and Zip who do his dirty work to keep him happy. He speaks with a neutral English accent (with lashings of Cockney). Although he is a steam engine, his deep, aggressive whistle sounds more like the air-horns fitted to modern diesel locomotives, trucks and ships. He is no. 1. He is based on L&YR Aspinall Class 27/Hughes Class 28 2-6-0 hybrid with a Fowler tender. He is voiced by Chris Tulloch in UK, and Kerry Shale in US.
- Zebedee is a rude tank engine and the rouge of his fleet. He speaks with a Liverpudlian accent. He's mean and vindictive on the outside, but on the inside there is much to his personality. Although loud, Zebedee's whistle produced a single flat note with a sound that would best be described as 'bwaa-!' He is no. 2. He is based on LMS Ivatt Class 2MT 2-6-2T. He is voiced by Nigel Anthony in UK, and Sam Gold in US.
- Zak is a threatening tender engine. He is a thuggish character, often aggressive and threatening. Publicity material for the series indicated that he saw himself as a potential leader of the Z-Stacks. Zak is the Z-Stack equvilent to the Star fleet's Hercules. His whistle sounds like Warrior's, but only deeper with two tones. He speaks with a gruff cockney accent. He is no. 3. He is based on SR Bulleid Q1. He is voiced by Shaun Prendergast in UK, and William Hope in US.
- Zug is a small tank engine. He speaks with a Eastern European accent (thought to be Estonian). Zug is a scheming and vindictive engine, he mainly works with Zip and is the brains of the operation, whereas Zip tends to be rather thick! Zug is obviously scared of the main Z-Stack Zorran and has a tendency to be somewhat nervous and jittery around him. Zug and Zip are the Z-Stack equivalents of Ten Cents and Sunshine, in that they are the smaller engines of the fleet, who work together, just like them and are often, plotting against them. Zug is not all that smart but compared to Zip he sure is. Zug's whistle has a hooting quality that sounded very much like a squeezy horn, but deeper. He is no. 4. He is based on Bagnall 0-4-0ST. He is voiced by Mike Mulloy in UK, and Kerry Shale in US.
- Zip is a dim-witted, but scatterbrained tank engine and Zug's best friend. He speaks with a neutral English accent. Zip is famously described as 'Zug, only worse'. His head is often in the clouds, and he is well known for being a coward. He is easily scared and sometimes speaks out of turn. He is very quick to back down when engaging in an argument, and is easily dominated. Zip is often described as being 'slow in the head', for it will often take him a while to catch onto things, even basic terms and phrases like devious. He is mostly out of plans, but may do his own, screwing up the original. Zip's whistle, much like Star tank engine Sunshine, had a 'whooping' sound, but was deeper, with a middle-to-low pitch. Whilst Zip and Zug are a similar wavelength, and have often been comparied with Ten Cents and Sunshine, Zug is much more skeptical of the pair, whilst Zip is quite the opposite. He will often follow along with Zug's plans in any situation, even if the concept of doing so causes him to loose his nerves. Zug often takes advantage of Zip's naivity to keep himself out of danger. He is no. 5. He is based on Hudswell Clark/Kiston No. 5459/Austin No.1 hybrid. He is voiced by John Baddeley in UK, and Sam Gold in US.
- 98462 and 87546/Alfred and 87546 are rude, spiteful, impolite, and nasty steam tender engines. They are mean to the other engines, notably Edward, Gordon, and Henry. 87456 once refused to work, whilst 98462 was spiteful to the tank engines, which is why they were soon dismissed from the railway. It is not known what happened to them since the decline of steam. Alfred98462/is an express engine. He was a conceited engine who thinks tank engines are useless, even if they have 14 wheels or their name is Stevenson. Alfred/98462 is based on the LNER Holden B12. 87546 is a mixed-traffic engine. He was a grumpy and lazy engine like Dennis and refused to pull goods trains. He learned his lesson with having a collision with Neville. Now 87546 became the Governor's private engine and named Crovan. 87546 is based on the LNER Gresley B17. They are no. 98462 and 87546. Alfred/98462 was painted LNER apple green but was painted blue with red and yellow lining and his name withdrawn from him. While 87547 is painted blue with red and yellow lining. In May of 2014, Crovan came into Knapford, boasting like usual. After Helen said he was a disturbing sight, Crovan called her a "wooden old cow." Later, he took Helen to Tidmouth to be washed, and then went off. When he came back to collect her, he found her talking with Oliver and Toad, who were in the siding next to her. Crovan was annoyed and rudely told Oliver to leave. After Toad said that he would like to take the governor, Crovan scoffed this and harshly insulted Toad. He puffed away, laughing. On the way to Tidmouth with the Governor to collect security, he apparently blew smoke at Helen, who purposely made the journey difficult for him. Because of this, he was in a bad mood. He got very angry when the driver told him he had to go into the siding, which Crovan thought was dirty and undignified. His anger erupted; he used obscene language and shunted into the siding so fast that he crashed through the buffers, derailing his tender and Helen. The governor was furious and traveled with Toad and Oliver instead, much to Crovan's anger. When the governor came back, he threatened to turn him into a sewage tank if he continued his nasty behavior. In 2017, The Flying Scotsman visited Sodor and Crovan was jealous of Scotsman. He thought he was being over granted, but after he and Spencer (who he had a rivaly with) had a race, Crovan said that he was bound to have an accident of get into a mess of some kind. But he soon ate his own word's when the points had been changed to the Harbor and almost crashed into Henry and Salty and fell into the sea. While underwater, Crovan realized that his personality was becoming much like Alfred's. After being fished out, the Fat Controller spoke severely to him about his behavior. That evening, The Flying Scotsman helped him to get his act together shortly before he, Gordon and Spencer were making there way back with their Special Enthusiasts Train. Spencer had hit a tree branch and it punctured his piston Crovan rescued the train. Crovan's friends are Gordon, Spencer, Flying Scotsman. Their enemies are Edward, Gordon, Henry, Spencer, Duck, Oliver and Toad. Alfred/98462 is voiced by Tim Curry in the UK and the US and while 87546/Crovan is voiced by Matt Wilkinson in UK, and William Hope and Martin Sherman in US.
- Horace is a rude and arrogant tender engine. He is mean to the other engines, notably Percy. Horace arrived on Sodor to help with extra heavy work. He bullied him, refused to work and was spiteful to tank engines. The Fat Controller sent him away for being rude, nasty and bullying. Horace is based on the LNER Class D14 with a Fowler tender. He is painted dark green with red and yellow lining. His model was recycled from Royal Claude, and later repainted and modified to be reused for Molly.
- Jinty and Pug are shunting tank engines. They and five other engines were borrowed from the mainland to run the North Western Railway while the engines visited England. Jinty ran Thomas’ Branch line while Thomas was away and later helped when Thomas crashed through some buffers. Percy knew them before they came to Sodor. Jinty is based on an LMS 3F 0-6-0T. Pug is based on an LMS 0F Kitson 0-4-0ST. Jinty is no. 47281. Pug is no. 52312. They are painted black.
- King James I is a GWR 6000 4-6-0 tender engine who worked alongside Duck in the days when he worked in Paddington.
- Manus, Doalty and Jimmy are 3 of Toby’s brothers. According to “Toby, Trucks & Trouble”, Toby had several brothers, all LNER J70 tram engines like him. Toby is now old and his brothers have never been heard of since. It can be assumed that they were all sold to other private railways around England. Toby hopes they have been saved from the clutches of the scrap dealers. They are all painted Brown with black cowcatchers and side plates. LNER is written on the side plates in yellow.
- Royal Claude is a Claude Hamilton Locomotive from the LNER that was around whilst Toby was working at the Yarmouth Harbor as part of the LNER. He was built in 1904 by James Holden. He is the same class as Molly. It can be assumed he works on the main line. He is painted green and he is LNER no. 8783. His model was later repainted and modified to be used for Horace.
- Wilbert (formally named G.B. Keeling) is a blue Hunslet WD 0-6-0ST from the Dean Forest Railway. He is very sensible and polite, and does his best to work well. Wilbert is also clever and inventive. Wilbert is based on the LNER Class J94/Hunslet Austerity 0-6-0 saddle tank. He is no. 3806 and painted navy with red lining and black wheels.
- Sixteen was a troublesome Hunslet WD 0-6-0ST saddletank engine working in an unnamed steelworks. Sixteen lived with several other engines at a steelworks, where his job was to take trucks of slag to a place called the "tip". Sixteen wanted to go past the "DANGER" board, and managed to do so one rainy day, blaming the incident on the trucks. His fireman was told to reverse him, but before he could do so Sixteen tilted and landed on the ground on his side. He was rescued and sent to the sheds in disgrace, but luckily for him he was purchased by a preservation group on the Midlands and now works on their railway. He is no. 16. Sixteen is painted reddish-brown with beige wheels and black and yellow hazard stripes on his bufferbeams.
- Albert is Thomas' father. His character appears to be like that of Thomas - he described Albert as being gentlemanly and polite. Albert is based on the Parker J1 2-4-2 class, rebuilt from the earlier E1 class of 2-4-0 tank engines of 1870, which were built originally by Sharp, Stewart and Co. Albert is painted in the Furness Railway's red livery with "FR" written in yellow on his sides.
- Morris, Jasper, Grunt and Bob are Sixteen's friends. When Sixteen worked at the Steelworks, he worked with some other industrial tank engines who were described by Wilbert as his friends. Unlike Sixteen, they obeyed the rules and never went beyond the "DANGER" notice at the tip. They tried their best to warn Sixteen not to go beyond the "DANGER" notice, to no avail.
- The workshop engines are many engines that appear in the works. The first one is a black 0-6-0 tender engine with red stripes resembling Edward. The second is a blue 0-8-2 tank engine resembling Thomas. The third is a large red 4-6-2 tender engine with black lining resembling Gordon. The fourth one is a green 4-4-0 tender engine with Red Lining. These engines were covered with tarpaulins (Gordon, James, Thomas, Henry and Edward). One is a small red Saddle tank engine and the same class as Percy. The other one is a blue engine resembling Wilbert with Blue wheels. Edward met some engines at the works. One is a green engine resembling Murdoch with smoke deflectors. Another one is an electric multiple-unit. These EMUs are still used on branch line services in Britain. A third engine can be seen right behind Edward but cannot be seen clearly.
- The Foreign Engine or sometimes known as the Big City Engine is a tender engine from LMS built at Crewe in 1934. He once came to Sodor and argued with Duck and Gordon about the name of Kings Cross. Gordon argued it was Kings Cross, Foreign Engine argued Euston and Duck argued Paddington. The argument continued even after the engine left. He is painted LMS "Patriot" 4-6-0. The engine is painted dark green with red lining and grey wheels and cylinders.
- Percy’s friends are four 1377 Class 1F 0-6-0 tank engines from the other railway. Their real names are unknown. Percy once met them at Vicarstown and told them of the time he braved a flood to help Thomas, when Henry came along and told them to leave.
- Jinty and Pug's companions are visiting engines. These engines came to Sodor with Jinty and Pug to run the line while the engines were on display in England. They are painted in the B.R.'s black livery.
- Dave is a Brunswick Green Great Central Railway's O4 Class 8F 2-8-0 tender engine. In the late 1950s, Gordon would stop at Vicarstown with the Express and an engine from the Other Railway would take the train on to London. One day, the engine pulling the Express that day rolled over while coming out of the yard, blocking the line. With permission from the Fat Controller, Gordon took the train on to London.
- Pete is a dirty black GCR Class 8K 2-8-0 heavy freight tender engine. He is closest friends with Dave, who took the Express before rolling over and coming off the rails as he was coming out of the yard.
- The scrapyard engines were paint-losing broken engines. All four had lost their paint and were waiting to be scrapped on a siding. The engine on the left seems to be a GWR 2251 Class 0-6-0 tender engine. The engine on the right seems to be a LNWR 0-8-2 tank engine with its trailing wheels, bunker and back end of its cab already cut off. The engine behind the engine on the right, on the same track, seems to be another tank engine with its smokebox door and its side tanks already removed. The fourth engine, on the far right, appears to be another tank engine.
- The Old Engine is an unnamed LNER GER J15 0-6-0 goods tender engine, built at Stratford works by TW Worsdell in 1913. When Toby visited the Seaside branch line, he noticed the Old Engine struggling with a load and offered to help himself. He is described as being younger than Toby. The Old Engine is LNER no. 1020. The old engine was painted in BR black, but his paintwork was tarnished by a covering of dirt.
- Old Stuck-Up, so named by James, is a haughty BR Class 40 1Co-Co1 diesel. He was built at Vulcan Foundry in 1960 and came to Sodor in 1983. BoCo was to show Old Stuck-Up, who then had not received his nickname, around, but when the diesel saw steam engines in the shed he refused to go further and insulted the railway for keeping them in service. A furious James bestowed upon him the nickname "Old Stuck-Up". The next day, Old Stuck-Up was about to leave when he remembered he needed refueling. He attempted to use BoCo and Bear's part of the shed to be refueled and cleaned, but slid on cleaning fluid on the rails and thus crashed into the back of the shed.

Some time after his arrival, Bert took offence when the Reverend W. Awdry and the Reverend Teddy Boston accidentally sprayed him with mud while passing him in their car, and in retaliation, Bert drenched the Reverend Teddy Boston with water when he took a ride in Bert's cab. However, both parties made up and as a result, Bert was featured in the Reverend W. Awdry's next book, Small Railway Engines, Bert, along with the other engines were offered to be in the Reverend's book if they behaved. When a rescue team went on a mission to look for Duke, they often rode on Bert's train, for a long time Bert had trouble with steaming. One day, as he was pulling a passenger train, his tender coupling broke off as they left the station. He didn't want to "stick" around, but the mention of the word "stick" encouraged his driver to bring glue to temporarily repair his coupling hook. This was what his driver called "Sticking Power".

- Mike is a strong red engine who prefers goods trains to passengers. He is the youngest out of the original three Arlesdale Railway engines, Mike worked on an unnamed line in England until 1967, at which time their line closed down and he, Rex and Bert, were sent to Sodor to work the Arlesdale Railway. Not long after arrival, Mike mocked Duck when the latter had trouble with his whistle making unusual noises, which lead to Rex telling Mike to lose his whistle. While pulling a passenger train, a stray cow had wandered onto the line and Mike whistled so loudly to make her move that his whistle flew off. This meant that his crew and passengers had to whistle for him. To make matters worse, there were no spare whistles for Mike so he was sent to the quarries for the rest of the day. Mike, along with the other small engines, were offered to be in a book about Duke if they behaved. When the rescue team found him, Mike brought tools to help him out of the shed, years later, a few months after Jock came into service, Mike decided to pay the new engine back for all his cockiness. So, whilst double-heading a passenger train, Mike reduced steam after the Green, causing Jock to pull him and the passenger train alone. However, Mike's plan backfired when his injector failed on the return journey and Jock had to take him home. After being mended, Mike apologised to Jock, he is based on the Ravenglass and Eskdale Railway's River Mite, and is voiced by Tim Whitnall in the UK and US.

He then refused to come out of the shed the next morning, but when he did, he only resulted in running into the back of the shed, cracking a shed support. He then felt ashamed of what he had done, but later redeemed himself by rescuing Rex when his steampipe leaked and needed his train. Believing Frank shouldn't have to do rescues, the Small Controller realized the railway needed another engine, he is based on the Ravenglass and Eskdale Railway's Perkins, and is voiced by Steven Kynman in the UK and US.
- Jock named by Douglas for his yellow livery, is the newest steam engine on the Arlesdale Railway, and the strongest, after Rex's steampipe began leaking one day and Frank had to take his train, the Small Controller began thinking they needed another engine, and so he arranged for Jock to be built. When Jock first came out for testing he was still unnamed. Jock's paint colour reminded Douglas of his days on the Highland Railway, and he suggested the name "Jock" for the new engine. The Small Controller and Jock liked the name so it stuck, later on, Jock pulled a doubleheader with Mike, who resented Jock's popularity and arrogance, and tried to teach him a lesson by cutting off steam, forcing Jock to do all the work. The prank backfired when Mike broke down on the homeward journey, and Jock had to pull both him and the train. That evening, the two engines made up their quarrel, and Jock resolved to be less conceited in the future, he is based on Ravenglass and Eskdale Railway's "Northern Rock", and is voiced by Matt Wilkinson in the UK and US.

- Elsie is a small luggage van that operates with Toby, Henrietta and Victoria. After Toby’s line closed, Elsie was brought with Toby and Henrietta to Sodor.
- Troublesome Trucks are so nicknamed because they can be quite troublesome and love to play tricks. No one save for Edward, Stepney and Salty like the Trucks as they have been the cause of many various accidents. Their behavior perhaps could be best described in the statement “Every wise engine knows you cannot trust Trucks”. Trucks could be considered the rebels of the railway, as most of them love to cause mischief, confusion and delay. They will play tricks on an engine based on how they treat them. Most accidents caused by the trucks are a form of revenge due to mistreatment. If an engine is having a bad day, makes a mistake or is easily played upon, then the trucks begin their wild antics of singing, name calling, holding back, shoving, bumping, giggling and so on. Trucks have all sorts of different bases. Some are 7-plank mineral wagons; others are twelve-ton stock vans, eight-ton cattle vans or tankers and so on. The Trucks rarely have names but in some rare cases they do such as S.C.Ruffey, Fred Pelhay, Hector, Rickety etc.
- S.C.Ruffey (pronounced Scruffey) was a private owner’s ballast wagon. He was the leader of the Trucks and when Oliver returned after falling down a turntable well, S.C.Ruffey and the trucks sang rude songs about the event. Toad worried by the lack of respect for the engines, consulted with Duck and Oliver and made a plan. Oliver then shunted Scruffey and his lieutenants, and prepared to pull them. Scruffey rallied the trucks into holding back, but this only resulted in Scruffey being pulled apart. Scruffey was later repaired but he says nothing at all anymore. In 1998, Scruffey met his end when he (who was now just a regular truck) and the other trucks were pushed into the Mine shaft and crashed causing an avalanche. Has a normal English accent.
- Hector is a large black Coal Hopper. When he first arrived to Sodor in 2007, he was seemingly mean and aggressive. He was a pain for Bill and Ben when they towed him into the yards. Later he was apparently the long awaited new leader for the Trucks since S.C.Ruffey was destroyed. He struck fear into Thomas and he was afraid to shunt Hector for James and Edward’s train. Though after he scared Rosie away, Thomas had decided to stand up to him and he bumped him causing him to crash through some buffers into some Coal. Hector had decided to confess to Thomas that he was mean to cover up the fact that he was scared of being loaded with Coal. After being helped back onto the rails by Rocky, Thomas showed him that being loaded with Coal is quite fun actually. Has a moderate Welsh accent.
- Toad is a Grey Great Western Breakvan who escaped with Oliver and Isabel from scrap. Unlike the rest of the trucks, Toad is devoutly respectful of the engines - he even addresses them as "Mr." - and incredibly polite. Toad is also somewhat imaginative and a bit of an optimist. Toad worked with Oliver on the Great Western Railway before being threatened with the prospect of scrapping. Oliver, Toad and an autocoach named Isabel ran away for the greener pastures of the North Western Railway, but Oliver ran out of coal en route. Luckily, they were rescued by Douglas and brought back to Sodor, where Toad asked to be Douglas' Breakvan to thank him. When Scruffey began to start a trend of disrespecting the engines, Toad had the idea for Oliver to show Scruffey and his lieutenants the error of their ways. This turned out better than expected, for Oliver pulled Scruffey apart and won back the respect of the trucks. Has a mild Welsh accent.
- Rocky is a large Breakdown Crane. He arrived to Sodor in 2006 and Gordon and Edward were skeptical about his abilities, noting that Harvey could travel under his own power. Later, Edward carelessly left the docks before his cargo was properly secured, causing his pipes to spill onto the mainline. Edward was adamant that Harvey clear up the line, but the little engine was too small to finish it quickly, and as a result Gordon crashed into the pipes. Edward returned to Brendam to pick up Rocky, who cleared the line and brought Gordon back to the Rails. Since this incident, Rocky has become an invaluable asset to the railway. He is frequently called upon to lift loads and help out after accidents. Has a thick Irish accent.
- Isabel and Dulice are Oliver’s coaches. Isabel was saved from Scrap with Oliver and Toad by Douglas. The origin of her name comes from the fact that she has a bell. Dulcie was saved from scrap along with Duck’s coaches, Alice and Mirabel by The Fat Controller. He gave her to operate with Oliver and Isabel.

- George is a grumpy steam roller who has strong dislike for the railway wanting them to be replaced with roads. When he arrived on Sodor in 1962, he immediately entered a conflict with Sir Handel, who was boastful about his broad tyres, which Skarloey decided to trick him into confronting George. After doing so, the two disliked each other immediately. One afternoon, Sir Handel was taking a Goods Train along a road-railway parallel which George had accidentally smashed into the side of Sir Handel’s Train. As a result a fence was built between the road and railway. When the work was over, the workmen took George away which Sir Handel took credit for. In 1980 George was to do some of Diesel 10’s biding and smash every buffer on the railway in search of the magic buffers. After that George worked around Ffarquhar where he once confronted Daisy. He and the workmen had left some road cones where they were working which one day; the wind blew on the rails. When Daisy passed through, they struck the Cone, jamming her brakes. Daisy was convinced George did this on purpose. In 1998 George caused more trouble, this time on the Main Line. He paved over a railway line causing Thomas to crash and refused to move for Duck which caused Gordon to destroy a Truck still stuck on the main line while taking the express.
