Olwin is an older female green steam locomotive who is very wise and kind.
Olwin is the most motherly of all the Chuggington characters. Olwin likes to keep her paint work looking pristine and would rather not be asked to complete dirty tasks. She is happy to help the trainees but sometimes embarrasses them by calling them "little chugg-a-chuggs". Olwin is a well respected engine and is always there when a chugger is in need of a 'bumper' to cry on!
Basis[]
Olwin is similar to an LNER Class A4, minus the tender.
