Diesel Era Staff/photos as noted
Penn Central’s (PC) relatively short tenure (1968–1976) and the railroad’s financial challenges limited new motive power purchases. In researching the road, you’ll discover that some of PC’s new diesel locomotives arrived as the result of orders placed by the merging partners before the road was a reality and delivered by diesel builders at or just after the February 1968 startup of the newly merged system.
This survey focuses on two of Penn Central’s six-axle diesel locomotive acquisitions that almost wore and served Pennsylvania Railroad (PRR). Pennsy had been buying six-axle models from Alco and General Electric (GE) during the 1960s. The road was the only participant in Penn Central that was a six-axle user.

Following its Alco C-628 (6300–6314) and C-630 (6315–6329) buys, PRR ordered 15 C-636s delivered to PC in early 1968. Pennsy’s GE six-axle U-boat roster included U25Cs (6500–6519), U28Cs (6520–6534), and U30Cs (6535–6539). Arriving the month (February 1968) PC became a reality were 20 PRR-ordered U33Cs. Four more U33Cs (6560–6563) joined the roster in June 1968…

ABOVE: PC 6561 (GE 36865) is from a June 1968 delivery that added four more U33Cs (6560–6563) to the road’s roster. These were not known to be part of the order placed by PRR before the merger, but two are shared here to complete the look at these U33Cs on Penn Central. All examples of U33C owned by PC were Phase IIa, and possessed the wide overhang on roofline over the radiator section and included the angled connection, or wings, be-tween the radiator section and engine compartment area of the long hood. Note the ACI Cartrak label below the “T” in Penn Central on the long hood. The GE builder’s plate is located on the sill above the first two axles on the lead truck. Conrail is days away from becoming a reality, when this March 27, 1976 shot was captured at Kearny, N.J. —Richard Louderback photo/Kevin EuDaly collection
