This HO Scale Class P5a Boxcab Electric from Broadway Limited is ideal for your 1930s and later layout. Although the original intention was that they work passenger trains, the success of the GG1 meant that the P5 class were mostly used on freight. A single survivor, prototype 4700, is at the Museum of Transportation in St Louis, Missouri. The first P5s were built with box cabs. A grade crossing accident in which the crew was killed led to the substitution of a streamlined steeple type cab in later production, a design which was also applied to the GG1. Orders were placed for 90 production locomotives classified P5a due to minor changes from the prototypes. Production was split between General Electric and Westinghouse. The GE examples were assembled at GEs Erie, Pennsylvania facility, still a locomotive assembly plant today--while final assembly for the Westinghouse order was subcontracted to the Baldwin Locomotive Works. This detailed P5a Electric features full Paragon3 sound and DCC for realistic sound and motor control complete with back EMF for smooth slow speeds. The Paragon3 sound system works with all Broadway Limited Rolling Thunder(TM) advanced sound systems. Other features include a heavy die cast body and chassis; smooth-running drive, applied details; directional warm white LED lighting and magnetic knuckle couplers. The HO Scale P5a can be operated on all DCC systems as well as on standard DC railroads (with limited sound functionality). This model has wheels profiled to operate on Code 70 and larger rail and curves of 18" radius or larger are recommended. The detailed electric comes in multiple roadnumbers for each railroad when appropriate. The Class P5a Electric is one of many Broadway Limited HO Scale Paragon3 locomotives.
