Requiring additional diesel types to finish out the retirement of steam, the PRR made one last purchase of EMD's F-unit series with the FP7A dual service locomotives - these would allow shorter passenger routes to be maintained without the expense of using the larger E-units. The FP7A had a slightly longer frame to accommodate a boiler water tank aft of the front truck. The order also included twelve matching F7Bs.

After a career that centered on the western regions of the PRR system, most of the FP7A/F7B fleet made it to Penn Central, although most were retired in the following years. The final survivors were retired by Conrail in 1978.
