The PRR's Q1, a single prototype built in 1942, was an 4-6-4-4 duplex design with the rear cylinders reversed and under the firebox to allow larger drivers. The engine was built for fast freight but the cylinder locations resulted in a smaller firebox that could not maintain boiler pressure under load, limiting its sustained speed. It had streamlining when it was first built, but it was removed in 1944 because it interfered with maintenance and was not that effective at low speeds. The engine was last used in 1948 and scraped in 1949.
The is a 3rd Rail model.
