First of a great line

PRR 1737, built in 1914, was the first of the road’s 425 class K4s 4-6-2 Pacific steam locomotives. Built until 1928, the K4s worked passenger trains all across the vast system, the last ones being retired in 1957 when PRR ended steam usage. Prototype 1737 is shown in as-built condition; later modifications included bigger tenders, power reverse, stokers, electric headlights, and drop-coupler pilots. Two have been preserved.
