Molly is a powerful, bright yellow tender engine who usually works at the Coaling Plant.


When she first arrived on Sodor, Emily teased her for taking "empties". Thomas wanted to make her feel special, so he helped her make the trucks look special by covering them with tarps and decorating with lights. However, one of the tarps flew off, and caused her to feel embarrassed, and steam away. Thomas eventually helped her to the Coaling Plant, and she found out that "empties" were very important after all. She was one of the engines who laughed at Emily when she worked with Whiff, and she advised Thomas to slow down when he was taking a sail boat for the Mayor of Sodor.

In The Great Discovery, she received news from Bill and Ben that Stanley had found Thomas.


Molly is a powerful, bright yellow steam engine. She is proud of her strength and is happy to put it to use as one of Sodor's bigger engines. She often works pulling empty trucks to the coaling plant. Because she is a sensitive engine, she often worries about fading into the background. Sometimes taking "empties" makes her feel less important and sad, but in the end, she will usually see that taking "empties" is a vital part of operations and an important task after all. Molly has a peacekeeper attitude, tends to be rather sensible, and is looked upon as a "big sister" by some of the other engines. However, she is a sensitive soul, who can be easily embarrassed and can get upset by conflict, and will steam away to avoid it, but will usually have the courage to do what she thinks is right. Molly likes to be as good as everyone else and wants the other engines to think the best of her. However Molly killed Lady, she stay of the seven engine, Her blame for Emily and Rosie, Diesel 10's side pain and he saves her, Also Molly who killed Charlie.


Molly is based on a Great Eastern Railway D56 Claud Hamilton.

  • Molly appeared with a larger face in promotional shots and in certain Thomas and Friends magazine stories. This is assumed to be a prototype face, as it was never used in the television series. The face was also used on her Take-Along card, and all merchandise lines except for the Wind-up line. The TOMY and TrackMaster range face covers the whole smoke box but is designed like her standard face.
  • On the newly designed Official Website, Molly's promo has her large face.
  • Molly's whistle sound is a two-tone variation of Gordon's whistle.
