The Pennsylvania Railroad K4s is an American steam locomotive class built with a 4-6-2 Pacific wheel arrangement, introduced in 1914 and produced in large numbers over the following two decades as the Pennsylvania Railroad's standard express passenger locomotive. Renowned for its distinctive appearance and dependable performance hauling the railroad's premier passenger trains between major eastern cities, it remained in front-line passenger service for decades and became one of the most recognized American steam locomotive classes before being displaced by diesel power after the Second World War.
