The Pennsylvania Railroad K4 was a class of 425 4-6-2 steam locomotives built between 1914 and 1928 for the Pennsylvania Railroad (PRR), where they served as the primary mainline passenger steam locomotives on the entire PRR system until late 1957.

Pennsylvania Railroad 1361 is a K4 class 4-6-2 "Pacific" type steam locomotive built in May 1918 by the Pennsylvania Railroad's (PRR) Juniata Shops in Altoona, Pennsylvania. It hauled mainline passenger trains in Pennsylvania and commuter trains in the northern New Jersey Shore on the PRR until its retirement from revenue service in 1956.

For more than thirty- five years the engine hauled trains of the iconic PRR passenger fleet over the main line, first between New York and Pittsburgh and later, after the eastern lines. When the locomotive was finally retired in 1956, K4s 1361 had rolled up 2,469,000 miles—the mileage equivalent of ten round-trips to the moon.

Here is an original photo that I took at the Pennsylvania Railroad's Horseshoe Curve near Altoona, Pennsylvania, during mid-May of 1966. Shown here are three PRR engines pulling a westbound mixed-cargo freight train around the apex of the Horseshoe Curve. Also visible is PRR K-4S (4-6-2) "Pacific" #1361, plus lots of budding trees!

The PRR was looking for a new more powerful locomotive and bought its first "Pacific", an experimental 4-6-2 built in 1907, by the Pittsburgh Works of the American Locomotive Company. This single locomotive was designated as Class K-28 and given road number 7067.

The PRR K4s was the largest steam locomotives ever built by the Pennsylvania Railroad, and it is no surprise that they are still popular today with railfans all over North America. This blog post will discuss this Pennsylvania railroad icon’s history, which spans both World Wars I and II as well as peacetime between them.

In September 2021, two major milestones were reached. First, the weld defects in the steam dome flush patch were repaired. Secondly, the firebox and rear flue sheet were removed, both of which had posed serious concerns. Upon initial inspection by FMW, the firebox failed to comply with the minimum factor of safety (FoS) rating of four.

Utilizing these scheduled excursions, K4s 1361 will offer immersive and memorable experiences for paying customers through living history programs and much more. Historically appareled hosts within each passenger car will serve as docents highlighting the travel life and culture of post-World War II America.
