For over a decade, 3750 stood in for the prototype K4s, 1737, and was listed on the National Register of Historic Places in 1979. It is one of the two remaining K4s locomotives and, along with PRR 1361, was designated the official state steam locomotive in 1987 by the Pennsylvania General Assembly. HistoryPRR 3750 was used to haul the Pennsylvania Railroad's main line passenger trains such as the Broadway Limited. Despite the attempt by railroad management to replace the K4s with the K5 and T1, the K4s would remain in action until dieselization in 1957. The 3750 was spared from being scrapped because, when the Pennsylvania Railroad was considering steam engines for preservation, the first K4, 1737, had deteriorated to the point that it was not worth preserving. The Pennsylvania decided to scrap 1737 and use 3750 as a stand-in; 3750 received the original number plates and tender from 1737.{{sfn|Pennsylvania Railroad Rolling Stock|1978|loc=sec. 7, p. 9}}{{dead link|date=February 2019}} In 1921, 3750 headed up soon-to-be President Warren G. Harding's campaign train.[2] Three years later, it also was one of the locomotives that pulled Harding's funeral train. When the steam power era ended most railroads scrapped their locomotives. The PRR however took pride in their engineering and mechanical legacy. PRR histoiran Dan Cupper gives much credit to a former Chief of Motive Power for the initiative to preserve examples of their most successful engines at their Northumberland, Pennsylvania roundhouse. In 1975 PRR 3750 was moved to the Railroad Museum of Pennsylvania in Strasburg. The entire PRR collection came under threat in the 1980s when the PRR's successor, the PennCentral estate, sought to raise cash by selling them for scrap. The Pennsylvania Legislature intervened and forgave some back taxes in exchange for deeding the collection to the state.[3] The Pennsylvania General Assembly designated 3750 and 1361 the official state steam locomotives on December 18, 1987, while also designating the GG1 4859 the state electric locomotive in the same bill.[4] PreservationAs of 2019, the 3750 sits on static outdoor display at the Railroad Museum of Pennsylvania.[5] The museum's volunteer group plans to have 3750 cosmetically restored prior to it being placed in a planned roundhouse.[3] See also
