This Pullman 12-1 heavyweight sleeper is painted Pullman Green with metallic gold lettering. Owned by Santa Fe, it displays the ‘Pullman’ name across the top and ‘Red Oak’ across the bottom, also in metallic gold. It runs on six-wheel passenger trucks. The introduction of the steel cars brought the end of the luxurious, artisan-crafted and custom-designed wooden cars which had been the rule since the 1880s. With the opening of the Pennsylvania Station in New York in 1910 and the Grand Central Terminal in 1913, passenger safety in the tunnels approaching these buildings demanded a more noncombustible material than wood.
