E33
The Virginian originally ordered ten E33's, but Norfolk & Western stopped all electric operations when they purchased the VGN. N&W sold the units to the New Haven (later Penn Central), which is how Conrail acquired them. They were in series CR 4601-4610.
E40
In 1956, GE built ten EP5 passenger locos for New Haven. The units had a small roof pantograph, a 600v DC 3rd-rail shoe, and two pantographs collecting 10,000v AC, which an Ignitron rectifier converted to DC. Penn Central reclassed EP5's as E40's. Most E40's were mothballed in Harrisburg on April 1, 1976, and then retired in 1977. They were series CR 4971, CR 4973-4977.
E44
Conrail inherited their E44's from Penn Central, which inherited them from the Pennsylvania Railroad. E44's were numbered CR 4400-4437 & CR 4460-4465, whereas the E44A's were numbered CR 4438-4459.
GG1
In 1935, industrial designer Raymond Loewy gave the GG1 its famous style-lines. PRR assigned GG1's to 4800-4938, which PC and CR retained. While associated with passenger service, the GG1 also hauled freight. Conrail retired most GG1's in 1979, but several lingered at least another year.
E10B
Conrail inherited the E10B from Niagara Junction. In December 1980, Conrail overhauled 4750, 4752, and 4753, fitting them with a smaller pantograph and 3-rail shoes, painting them black with the MTA logo, and then assigning them to Harmon, replacing the aging S2E's. CR stored and then disposed of CR 4751, 4754, and 4755.
S2E
The S2E's were some of the oldest, if not oldest, locomotives on Conrail's roster. They served in the New York area and were never renumbered. Those that survived onto Conrail were 4710, 4715, 4723, 4731, and 4733.
