Mack Railbus Model AC
The February 4, 1922 edition of Railway Age featured drawings of the Mack gasoline rail car built for the New Haven Railroad. The chassis of the motor car was made by Mack Trucks and the body by Osgood-Bradley Company of Worchester, Mass. The New Haven rail bus is nearly identical to rail bus "A" used on the Buffalo Creek & Gauley Railroad, a West Virginia short-line railroad best known for its use of steam locomotives until the early 1960s.
