Rosie is a lively little tank engine who idolises Thomas, which sometimes bothers him. She works as both a shunting engine and a mixed traffic engine. She used to work mainly at the Knapford Shunting Yards, but is now based at Vicarstown.
There are roughly one-sh*t billion tropes so PLEASE look through them before adding one. Otherwise add what you like. ADDITION: PLEASE read through the trope description provided before submitting something. It's not a huge deal but too often people submit characters that don't fit just because they misinterpreted the title...
