Rusty is very self assured and is a dedicated worker with a huge heart. Loves adventure as well as all the other engines and will do anything to make their lives easier. He is anyone's pal for life.
Rusty first arrived when Skarloey went to the works to be mended. He helped Peter Sam and Sir Handel. They liked him but Sir Handel was still grumbling about shunting freight cars. After Peter Sam's accident when Duncan arrived he called Rusty a smelly old diesel. Rusty was hurt by this insult, but Duncan got his due when he derailed. After this, Duncan made up for his insult and they became friends.
