Thomas the Tank Engine Wiki

― Sandy's catchphrase

Sandy is a light pink rail speeder who lives and works on the Island of Sodor. She is close friends with Carly and works with her at their maintenance yard.


Sandy is a very energetic speeder, and while not the biggest engine on the island, she still enjoys the company of her much larger friends, many of whom recognize that she is a valuable asset to their community. Sandy always participates in a game if she can, and one of her favorite aspects of a race is seeing who the winner is. As such, she will follow someone closely to see if they will win or not. Sandy is also very good with small repairs, swapping out Gordon's broken coupling with a new one in seconds without difficulty. Additionally, she is very inventive and enjoys playing in mud and sand, particularly the last one. Sandy is always ready to help out wherever possible, but at times she can go overboard and try to make a complex solution for a simple problem.

Technical Details[]


Sandy appears to be based on a Motorcar, which were self-propelled vehicles used for track maintenance. She seems to most closely resemble those made by Fairmont Railway Motors of Fairmont, Minnesota. Unlike real-life speeders, Sandy can extend a robotic arm from the front of her chassis and/or a winch, in addition to other tools.


Sandy is painted coral pink with two black stripes around her front and a yellow cab door. She has an aqua roof and two pieces of aqua tape on her sides. Her lights and other fittings are silver, while her bufferbeams and valences are painted gold.
