Pennsylvania Railroad 1361 is a 4-6-2 pacific type steam locomotive built in 1918 for the Pennsylvania Railroad by their own Altoona Works. As a member of the K4s locomotive class, it served its active career hauling mainline passenger and mail trains. Retired from revenue service in 1956, it was restored to operating condition in 1987 when mechanical problems sidelined the locomotive after only a year and a half of operation. The engine is currently owned by the Railroaders Memorial Museum in Altoona, Pennsylvania. It is one of the only two remaining K4s locomotives and, along with PRR 3750, was designated the official state steam locomotive in 1987 by the Pennsylvania General Assembly.

The K4s is considered the Pennsylvania Railroad's most famous class of steam locomotives, with a total of 425 engines produced from 1917 to 1928, and including the prototype that was built in 1914. The last of K4s stayed in service well into the late 1950s, until being replaced with diesel locomotives.

1361 was constructed in 1918 by the Altoona Works. On June 8, 1957, 1361 was dedicated and placed on exhibit at the Horseshoe Curve outside of Altoona. It had clocked an estimated 2.5 million miles (4.02 million kilometers) over its career. 1361 remained at Curve until 1985 when it moved back to the Altoona Works. It was replaced, at the curve, with the EMD GP9 diesel locomotive 7048, painted in Pennsylvania Railroad colors. 1361 was restored in 1987 to haul excursion trains. A year later, the main bearing and the drive axle suffered a catastrophic failure. 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.
