EMD E units were the backbone of the Pennsy's passenger fleet.


Freight Locomotives


f3 phII early

The PRR acquired hundreds of EMD F-units beginning in July of 1947. Complicating matters for railfans and modelers alike are the many "phases" of units that the railroad purchased. This document intends to point out the spotting features across the various models and phases.

There were 1807 F3/F5 units built, of which the PRR purchased 146 (8%). There were 3849 F7 units built, of which the PRR purchased 164 (4%). There were 372 FP7 units built, of which the PRR purchased 54 (15%).

The PRR did not purchase any of the earlier FT's or F2's, nor the later F9's, FP9's, or FL9's.

Road numbers in bold are in my personal collection (or on order).

 Notes:

 1. All F2-F7 Boosters have 3 equally-spaced portholes in the center third panel.

 2. While most roads opted for a large, angled number board, the PRR purchased the standard streamlined (small) four-digit numberboard.

 3. F3 Phase IIb: Hirsimaki's Black Gold, Black Diamonds, Volume Two indicates (p. 42) that the helper units were not equipped with trainphone antennas. But we know from photo evidence that the units were so equipped, but as delivered did not have trainphone antennas. This initial A-B-A helper demonstrator set was delivered to the PRR in January 1948. They served on the Pittsburgh Division and were retired in December 1962. Also during an overhaul in August of 1956 helper unit 9519A was rebuilt to F-5 specifications with heavier traction motor cables, a prime mover from unit 9782B, and the front replacement porthole panel from a phase 2 F-7A thus eliminating the chicken wire in this area of the carbody. It was reclassified EF15a.

 4. F3 Phase IV (F5): For the Pennsy the F-5 units went to work as "Snappers," the F-5 program never impacted the through freight units. Jack Consoli contests the generator as being one of the changes in this phase. However, the fact remains that, for the most part, these units appeared the same externally as the Phase IV's.

 5. The InterMountain F3's in Pennsy livery have incorrect (angled) number boards. It is also worth noting that the parts sprue used to manufacture this locomotive also contains the high fans required for a Phase IIa depiction.

3 The InterMountain F7 in Pennsy livery features a square window on the rear end door, so it should be a Phase Ib. Road numbers and othe spotting features would indicate a Phase Ic. The parts sprue used in the manufacture of this model also includes a round window door, making a correct Phase Ic depiction possible.

 Notes:

 1. F7s all rated at 1500 hp.

 2. Boosters all have 3 portholes instead of louvers.

 3. F7 Phase Ia: Initial Pennsy units featured streamlined (small) numberboards. As of July 1949 they switched to the 45-degree, four-digit numberboards. Greg Martin indicates that these units' windshields had raised, exposed gaskets.

 5. F7 Phase IIb/IIc: EMD offered a larger dynamic brake package (with 48" fans) but the PRR didn't purchase it.

 7. Not long after purchase, the units with the rear overhang had their overhang cut off.

EMD FP7, Class EFP15

The FP7 was introduced, with 4 extra feet of carbody added to accomodate a larger steam generator.

There were no FP7B unit produced. Rather, there were steam generator options for standard F7B units, of which the Pennsy purchased several which had previously been noted in the F7 table above.

The first two PRR ABA sets (9832A-9832B-9833A and 9834A-9834B-9835A) were painted in the passenger scheme of Tuscan Red with five Buff stripes. The remaining units were painted in the standard freight scheme.
