Based on the fanfic "Thomas leaves sodor" but only this time he doesn't go to Brighton.

In the AU story "sodor's legend of the lost treasure: Thomas leaves sodor" where Thomas The Tank Engine runs away from sodor after the dynamite incident and tried to explain to sir topham hat but he won't listen. So Thomas decided to return to his birth place, Brighton.

But my version however, he ends up in brittlewood in Equestria, along the way, he meets new friends: sunny starscout, hitch trailblazer, Izzy moonbow, pipp petails and zipp storm the mane 5. And together they must restore the magic and the pony tribes. During Thomas' journey and his new life in equestria, he was catching the eye and fall in love of a certain pony: Sunny Starscout.
