Amelia is a daredevil tender engine, and isn't afraid to do something. She is a mixed-traffic engine, and works on Thomas' branchline, but sometimes the main line when Henry is ill or away.
Amelia can be a handful, and Thomas acts like a big brother to her. Amelia has a crush on Edwin the V3 tank engine, who has a crush on her. She is based on GNR Stirling Single/LBSCR Class E2 4-2-2 hybrid. She is painted blue with number 70 on her cab.
