The F-16 class Pacifics were designed to haul express trains of 700 short tons over graded routes. They were similar in many respects to the ALCO No. 50,000, designated the Erie K-3 class, but were built by Baldwin. With a driver diameter of only 73 inches, they were well suited for the inclines. They were brought up to date over their service life, for example by installing a stoker. After the Second World War they could still be found in local traffic.
