Production: The PRR built 425 K4s between 1914 and 1928.

Features: The K4 had a boxy oil-burning headlight, round numberplate, and long wooden pilot in the early years. Later models had an electric headlight mounted on a bracket and a pilot made of horizontal steel bars.

Nicknames: One K4, the PRR 1361, was nicknamed "The Juniata Jewel" and "The Spirit of Altoona".
