American Model Toys - AMT HO Gauge Passenger Cars
AMT made HO gauge streamliner passenger cars as follows: Four-door Baggage; Combination or Crew Car; Day Coach; Dining Car; Bedroom-Roomette Pullman, and; Observation Car. The cars came in kit form or, for a dollar more, already assembled. They have one piece extruded aluminum bodies with die-cast ends, floors and trucks. Each car has two metal light sockets cast into the floor. The trucks are insulated from the metal floor by plastic grommets. An 18 inch radius curve was recommended for operation, but they could be used on even smaller radii curves (info from the August 1952 AMT Headlite newsletter).
