The advent of heavier, longer passenger trains at the dawn of the 20th century called for a new type of steam locomotive. The 4-6-2 answered that call in 1901. During the First World War, the United States Railroad Administration manufactured a standardized 4-6-2 for delivery to several railroads under the organization's control. The design proved so successful, that a number of railroads built their own copies of the design upon returning to private ownership. The Bachmann USRA 4-6-2 Light Pacific comes ready to run with an NMRA 8-pin plug, directional lighting, and authentic, prototypical detail.
