Ashima is a brightly-painted Indian tank engine. She is taking part in The Great Railway Show.
Ashima was invited to participate in the Great Railway Show for the Shunting Challenge. She, along with the other eleven contestants for the show, came to Sodor by mistake when the ferry they were on accidentally stopped at Sodor instead of England, and she was accidentally left behind when the ferry left with all the other engines except her. Ashima, lost and not knowing the way to the Mainland, tried to ask Thomas for his help, but Thomas, who was already jealous of her, refused to assist her. Ashima soon managed to befriend Thomas, and she convinced him that he did not need to change for the competition, and suggested that he participate in the Shunting Challenge, but Thomas was involved in an accident which put him out of the competition. Ashima was taken to the Mainland with the other Sudrian engines who would be competing in the Great Railway Show.
After arriving and watching the Best Decorated Engine parade, Ashima was questioned by Emily on why she did not compete, revealing to the Sudrian engines she would compete in the Shunting Challenge. She does so alongside Ivan, Raul, Gina and Thomas, who had managed to arrive to the Great Railway Show after all and took Percy's place. During the race, she helped Thomas hold Vinnie back when he was bullying Philip, and also pulled Thomas back when a pylon nearly fell on him. During the end of the competition, Ashima ended up winning after Thomas sacrificed his own chance to win when he spotted a derailed flatbed on her track, but the judges made the both of them the winners of the competition. Ashima returned to Sodor with the Sudrian engines, where she would then return back to India.
