One day, Thomas and Hiro are puffing happily to Knapford. Hiro sees a bend up ahead and slows down, but Thomas, delighted to show-off, speeds up with his heavy train of pipes which have not been properly secured. As Thomas races around the bend, the pipes tumble off of his flatbed and onto Hiro's line. Hiro cannot stop in time, collides with the pipes and falls onto his side.
It is not long before Edward arrives with Rocky, and Hiro is put back on the rails. The Fat Controller agrees that accidents do sometimes happen and tells Thomas and Hiro to get back to work. When Hiro tries to move, his wheels will not turn properly and the Fat Controller realises the damage is worse than they had thought. He sends Hiro to the Steamworks and Thomas puffs sadly away, feeling guilty.
That night, Thomas still feels bad about causing the accident. He explains to Percy that spare parts to fix Hiro are not easy to obtain because he comes from so far away. Then, Thomas remembers when he first found Hiro in the woods. Hiro had been stranded there for so long, that he had almost fallen to bits. This gives Thomas an idea.
Early next morning, Thomas sets off to Hiro's old forest hideout to look for some of Hiro's old spare parts. The forest where Hiro had been rediscovered is very old and overgrown and Thomas has to push his way through branches and brambles, but no matter how hard Thomas looks, he cannot find any spare parts. Thomas decides it is time to give up and head back, but before he manages it, the old rails give way beneath him and Thomas derails into the mud.
Meanwhile, outside the forest, Percy is pulling the mail. Thomas yells for help as loudly as he can, but Percy is unable to hear him. A bit later, Thomas hears Harold flying over the forest. He calls for help, but Harold cannot hear him either. Then, Thomas has an idea and blows steam out of his funnel high into the air. Harold is surprised to see steam from an engine rising from the treetops and flies away to get help unbeknownst to Thomas who is starting to give up hope.
The light in the forest starts to fade and Thomas hears all kinds of spooky noises. Then, there is a scary rumbling noise. Thomas wonders what it can be as it gets nearer and nearer. Thomas is thankfully relieved as it is only Percy with Rocky and the Fat Controller. Thomas realises he has been saved and is sent to the Steamworks.
At the Steamworks, Thomas tells Hiro all about his exciting adventure and apologises for not being able to find any spare parts. He wishes Hiro can be fixed like him, but Thomas is surprised when he discovered that Hiro is fixed. Hiro explains that after last time, the Fat Controller ordered a lot of spare parts in case he ever broke down again.
Thomas and Hiro roll happily down the line side-by-side, being extra careful on the sharp bend. Thomas is delighted to be puffing with his friend again and they are both truly 'Masters of the Railway.'
Tropes:
- An Aesop: It's important to let someone know where you're going so you won't cause problems.
- Go Back to the Source: Thomas believes the woods where he first found Hiro would have parts that would fix him.
