Thomas and Friends: Tales from the Rails
Helping Hiro
S1 E2:
Thomas first met Hiro when he found him abandoned and in need of repair in the woods. It was not easy to get spare parts for Hiro and so, when Thomas causes Hiro to be derailed, he rushes to find him spare parts. Only Thomas hasn't told anyone where he is going, so when he runs into trouble nobody knows where to look for him!
