The K4s was the Pennsylvania Railroad’s premier passenger-hauling steam locomotive from 1914 through the end of steam. The K4s’ total length was 83ft 6in and it had a combined weight of 468,000lb. Along with it’s 80in drivers, the K4s produced 44,460lb of tractive effort. It was not uncommon to see a K4s easily pulling 12 coaches at 100+mph on level ground. The PRR K4s is widely considered to be one of the greatest steam locomotives designs of all time. It has been said that the Chief Mechanical Engineer of the London & North Eastern Railway, Nigel Gresley, incorporated much of the boiler design into his famous Class A1 Pacific. The K4s was used until the end of steam in 1957.
