The typical American old-timer cars are used on the museum trains running on the Wiscasset, Waterville, and Farmington Railway. They can be recognized by the clerestory in the center of the car roof. Usually, only 2 to 3 cars are coupled to a train pulled there by the small locomotives. Mixed trains of passenger cars and freight cars are customary. With the dark green paint scheme, the cars are the same as a widespread color scheme, which is also used on cars of the Durango & Silverton Railroad or the White Pass & Yukon Railroad among others.
