This Atlas Master(R) HO Scale Pullman Heavyweight 8-1-2 Sleeper is based on the Pullman Plan 3979 Sleeper. his design featured 8 sections, 1 drawing room, and 2 compartments in an attempt to balance the economy of sectional berths with an increased desire by travelers for more privacy options. The compartments, which included their own sink and toilet, provided enclosed travel for two, while the drawing room added sofa accommodation and floor space for an additional passenger. The arrangement of the rooms in the car also enabled the creation of suites for families or larger parties through connecting doors. The design proved very successful, with 250 cars being produced between 1927 and 1930. These 8-1-2 sleepers were found across the country in both pool service and dedicated assignments to many colorful name trains from the 30s through the early 60s, with several ending their careers in MOW service. The Atlas HO Scale models feature full interiors, scale operating diaphragms, ice or Pullman mechanical AC as appropriate, full underbody detail, window glazing, prototypical trucks and Accumate(R) knuckle couplers. These cars are designed for operation on 24" radius or larger curves. This detailed Pullman Heavyweight 8-1-2 Sleeper is one of many Atlas HO Scale passenger cars.
