Broadway Limited Imports HO 4422 K4s 4-6-2 Pre-War Version with Slatted Pilot, Pennsylvania Railroad #3846 (Equipped with Paragon3 Sound/DC/DCC with Rolling Thunder)

The Pennsylvania Railroad's K4s 4-6-2 "Pacific" (425 built 1914-1928, PRR Altoona, Baldwin) was their premier passenger-hauling steam locomotive from 1914 through the end of steam on the PRR in 1957.

Attempts were made to replace the K4s, including the K5 and the T1 duplex locomotive, but none was really successful, and the K4s hauled the vast majority of express passenger trains until replaced by diesel locomotives. The K4s was not powerful enough for the heavier trains it often pulled from the mid-1930s onward, so they were often double or even triple headed. This was effective, but expensive - several crews were needed. The PRR did have the extra locomotives, many having been displaced by electrification.
