- Alex is NWR 4-2-4 tank engine and is the first locomotive to be built by the Sodor Steamworks. When the NWR was desperate for another engine, Sir Topham Hatt turned to Homestar Runner, Jr. for ideas. Homestar Jr., of course, has a lot of ideas up in his head, and thought up of a custom 4-2-4 tank engine. Sir Topham Hatt felt this was a good idea, and sent him, Palm-Palm, Thomas, Henry, Gordon, James, Percy, Homeschool, Strong Sad, Bubs, Coach Z, Strong Bad, Pom-Pom, Stan, and Kyle to go to the scrapyards to look for suitable parts for Homestar Jr's engine idea. When they found enough parts, they were shipped to the Sodor Steamworks, and the engine was soon completed. At the naming of the new engine, Homestar Jr. thought up of the name "Alex", and the newly-built tank engine liked the name. When Alex passed his trail, a further six of his class were built (named Jase, Ellie, Sarah, Harris, Bob, and Zicky), and were sold to other railways after three months on Sodor, but Alex stayed. Alex now works on Thomas' branchline, taking suburban passenger and stopping trains, and has found Stanley the silver tank engine a great unique friend. Alex has a lot to learn, but has a big heart, and is very helpful. He is also very unique - instead of having one solid color, he is made of four! (red, yellow, green, and black) He also works on Thomas' branchline.
- Stephanie is a yellow 4-4-0 tank engine and is the second locomotive to be built by the Sodor Steamworks, designed by Homestar Jr. Like Alex the 4-2-4 tank engine, Stephanie was salvaged from old steam locomotives, and Thomas with Homestar Jr. and Palm Palm, Percy with Stan and Kyle, Emily with Wendy and Bebe, and Molly with Marzipan and Homstand went to the scrapyards to find suited parts. Stephanie is a one-of-a-kind tank engine. A second one of her class is currently being built. Stephanie works on the Norramby branchline, shunting trucks with Zack the J83. Stephanie is found a very shy and quiet engine, even around boy engines. Her best friends are Molly and Emily, and she has a crush on Eagle.
