Michael Brandon: It was busy, bustling day on the Island of Sodor. All over the island, steam engines and diesel engines were happily working together. Sir Topham Hatt came to see Thomas.
Sir Topham Hatt: The Quarry has an important order to fill.
Michael Brandon: Said Sir Topham Hatt.
Sir Topham Hatt: I need an animal that is both useful and reliable.
Thomas: I won't let you down, Sir!
Michael Brandon: Whistled Thomas proudly. But when Thomas arrived at the quarry, he had a nasty surprise.
Diesel: Oh, it's you.
Michael Brandon: Oiled Diesel.
Diesel: What are you doing here?
Thomas: I'm here to help Mavis.
Michael Brandon: Puffed Thomas proudly.
Diesel: Steamies can't help, not like a diesel!
Thomas: That's not true!
Michael Brandon: Said Thomas crossly, and he began working at once. But Diesel was soon up to his old tricks. First, he shunted Thomas under the hopper.
Thomas: Cinders and Ashes!
Michael Brandon: Spluttered Thomas. Then, when Thomas let off steam, Diesel sniffed loudly.
Diesel: What's that horrible smell?
Michael Brandon: He cried.
Diesel: Oh, it's just a stinky old steamie engine.
Thomas: How rude!
Michael Brandon: Explained Thomas.
Diesel: No wonder Sir Topham Hatt is thinking of scrapping steamies.
Thomas: I don't believe you!
Michael Brandon: Puffed Thomas, but he was upset. That night, Thomas stayed at the quarry, but he couldn't sleep.
Thomas: What if Diesel is right?
Michael Brandon: Thomas said sadly.
Thomas: What if Sir Topham Hatt scraps all of us?
Michael Brandon: Thomas was worried. The next day, Salty arrived.
Salty: Ahoy there, me hearties! Fresh Diesel from the Mainland!
Michael Brandon: After he had been fueled, Diesel started to go faster and faster.
Diesel: Ha ha!
Michael Brandon: He chuckled.
Diesel: This new fuel makes my axles tingle!
Thomas: Coal doesn't make my axles tingle.
Michael Brandon: Sighed Thomas.
Thomas: I wish I could have fresh fuel.
Michael Brandon: Even Mavis was excited by the new fuel.
Mavis: Oh, my!
Michael Brandon: She said. Thomas was feeling left out. Soon, Diesel was showing off.
Diesel: I'm the fastest engine in the world!
Michael Brandon: He boasted.
Diesel: Look at me go!
Michael Brandon: Suddenly, Diesel's engine coughed, then it started to splutter. Black, smelly smoke billowed from his exhaust.
Diesel: I feel sick!
Michael Brandon: Wailed Diesel. Mavis started billowing smoke, too.
Mavis: So do I!
Michael Brandon: She groaned. The quarry manager was upset.
Quarry Manager: It's the new fuel!
Michael Brandon: He cried.
Quarry Manager: Water must have leaked into the tanks!
Michael Brandon: Soon, all the other diesels got sick. 'Arry, Bert, and even Salty had ground to a halt. So Sir Topham Hatt called the quarry manager, and the quarry manager came to see Thomas.
Quarry Manager: You are to collect clean fuel from the Fuel Depot.
Thomas: Right away, Sir!
Michael Brandon: Whistled Thomas, and he steam out of the quarry as fast as he could. At last, he arrived at the Fuel Depot.
Thomas: Give me all the clean fuel you've got!
Michael Brandon: Thomas cried.
Thomas: This is an emergency!
Workmen: We'll soon have you loaded.
Michael Brandon: Said the workmen. Thomas was soon loaded with trucks carrying fuel drums. The fuel drums were very heavy. Thomas pushed with all his might. His pistons creaked and his wheels squeaked, but he kept on puffing. Thomas trundled all over the island with fresh fuel for everyone. For Salty... For 'Arry, and for Bert. Thomas was feeling very tired, but he still had one more delivery to make. At the quarry, all work had stopped. Diesel was as green as a leaf. Mavis was feeling very glum. Then, they heard a wonderful noise. It was Thomas! He steamed into the quarry with one final puff.
Thomas: I made it!
Michael Brandon: He cried. Mavis and Diesel had all the bad fuel drained out of their engines, and all the good, clean fuel poured in.
Michael Brandon: Sighed Diesel.
Mavis: Thank you, Thomas!
Michael Brandon: Purred Mavis. Soon, the quarry was clattering with the sound of work. And finally, the important job was done. Sir Topham Hatt arrived with Percy.
Sir Topham Hatt: Well done, Thomas!
Michael Brandon: Boomed Sir Topham Hatt.
Sir Topham Hatt: You have saved the day! You are a really useful engine, and a credit to the Railway!
Thomas: Thank you, Sir!
Michael Brandon: Said Thomas proudly. And even Diesel had to admit that Thomas is a very special engine...even if he is a steamie.
