[1] Rebuilt and re-classified as P-2, the 21 remaining engines were sent to the New York electrified zone to supplement the aging fleet of T-Motors that had been purchased starting in 1913.

In the 1920s the Van Sweringen brothers conceived of a new "Union" station for all trains coming into Cleveland via the various railroad lines in a concept similar to New York City's Grand Central Terminal.

As with other underground station projects, the existing steam locomotive technology would be unacceptable due to the large amounts of exhaust gases and soot expelled from the smoke stack.

[1] The solution was an electrification project that would see passenger trains using the terminal switch to electric power before entering the confines of the station area.

The units, painted in the New York Central style but lettered for Cleveland Union Terminal, went into service in 1929 and worked for the next 20 years running from Collinwood to Linndale and back with whatever passenger train needed to stop at the station.
