They were the first streamlined equipment operated in New England and acquired their name from the model trains that their design inspired.
[1][2] American Flyer railcars weighed about 55 tons and were built out of light-weight steel alloys such as Cor-Ten that made them about 15 tons lighter than earlier designs and allowed for the use of two-axle General Steel Castings trucks instead of the previously standard three-axle designs.
[1] They were designed by Walter Dorwin Teague, and the first order for 50 coaches, with an 84 passenger capacity, was placed by the New Haven Railroad with Pullman-Standard in March 1934.
[2] A Bangor and Aroostook car converted into MoW service survives at the Shelburne Falls Trolley Museum[5] Two examples of the type, both New Haven Railroad coaches, were purchased by the Railroad Museum of New England for preservation.
