Pennsylvania O Scale Premier 4-8-2 M-1b Mountain Steam Engine w/Proto-Sound 2.0

Between the two world wars, the Pennsylvania Railroad developed only one new freight engine design, the M-1 Class Mountain. It was their first fast freight engine, built between 1923-26, and was a resounding success. After the initial success of the Pennsylvania M-1, the railroad accepted delivery of 100 class M-1a engines from the Juniata, Baldwin, and Lima shops in 1930. The M-1as were quite similar to the M-1s. Among the most notable improvements were that the M-1a got Pennsy's first large capacity tender and had two air compressors instead of one. These fast and powerful dual service locomotives were especially useful for fast freight runs, and they became a recognizable symbol of fast Pennsy freight service. Despite Pennsylvania's interest in electric service, the 4-8-2 M-1a was successful enough to be a major workhorse for the railroad into the 1950s. The powerful and prototypically-detailed Premier Pennsylvania M-1a will be a valuable addition to the the collection of any modeler who needs freight delivered fast. Did You Know? Beginning in 1938 PRR began replacing the M1s' cast steel cylinders with lighter weight steel plate, saving 5,000 pounds of engine weight. Each cylinder contained 177 different pieces of 53 different shapes.
