The Green Express Coaches are primarily used for the Express pulled by Gordon. They are often used for other fast trains on either the Northern Coastline Railway or The Transportonian Main Line. They're also used for the Morning Express.

These coaches were sentient despite not having faces. Like many coaches, they do not appreciate being bumped by an engine and if they are not handled properly, they can get back at their engine.

One needs to be able to do at least 3 different impressions or accents.
