Pennsylvania Railroad (PRR) Diesel Roster: All-Time List

Last revised: September 22, 2026

By: Adam Burns

The Pennsylvania bought diesels late, and then it bought them from everybody. Mike Schafer and Brian Solomon date the first one to June 1937: Electro-Motive SW 3908, a 600-horsepower switcher, serial 680, later renumbered 5911. One yard engine did not convert a mechanical department that still believed in Juniata. Road freight cab units waited until the F3s of 1947. The FT was a model this railroad passed over. By the mid-1950s the roster ran through Alco, Baldwin, Electro-Motive, Fairbanks-Morse, Lima-Hamilton, and, from 1960, General Electric.

Baldwin at home, and everyone else besides

The class letters are the Pennsylvania’s own. The first letter is the builder: A for Alco, B for Baldwin, E for Electro-Motive, F for Fairbanks-Morse, G for General Electric, L for Lima. A 1,500-horsepower EMD road switcher is an ES15. A Baldwin shark cab is a BF16. Those letters are the Class column below.

Baldwin got the orders it got because Eddystone is in metropolitan Philadelphia. The railroad bought switchers, transfer units, Centipedes, passenger cab units, and the RF16 sharks, and it kept buying Baldwin power after the builder’s reputation on other railroads had already slipped. Three RF16s were rebuilt in December 1959 with Alco 12-251 engines and rated at 1,800 horsepower, class BF18. Their new numbers were 9632A, 9633A, and 9632B.

Electro-Motive became the volume supplier once the F3s, E7s, and yard switchers proved what the 1937 SW had only suggested. The passenger fleet settled on E8s. The freight cab units were F3s and F7s, with FP7s where a steam generator was required. Hood units followed: GP7s and GP9s, a pair of SD7s, SD9s, then the GP30 and GP35 and the six-motor SD35, SD40, and SD45. Even numbers and odd numbers on some of the SD45s were built as separate serial blocks, and the table keeps that split.

Alco covered the same ground, from S1s and S2s through FA and PA cabs to the RS27s and the Centuries. One C424, 2415, was rebuilt from Alco’s RS27 demonstrator 640-1. The C425s are class AF25. The fifteen C628s are 6300–6309 and 6310–6314. The C636s, order 3499, were delivered after the merger.

Fairbanks-Morse contributed H10-44s and the later road switchers, Erie-built cab units, opposed-piston C-Liners, and nine Train Masters. Lima-Hamilton’s contribution was the 2,500-horsepower center-cab transfer unit, classes LS25 and LS25m. General Electric began with 44-ton switchers and returned, after 1960, with U25Bs, U25Cs, U28Cs, and a short order of U30Cs. There were 59 U25Bs, numbered 2500–2548 and 2649–2658. Penn Central renumbered the 2500s into the 2600s, so the 2604 in the East St. Louis photograph is the former 2504.

The railroad also tried the Aerotrain. The locomotive was an EMD LWT12, number 1000, class EP12, photographed westbound at Altoona on July 18, 1956. It did not become a class.

Steam was declared finished on November 30, 1957. The diesel list below is the buying program that replaced it, including original numbers and the later numbers where the railroad, or Penn Central, changed them. A serial is the construction number. Where that number is already an Alco order and a unit, as on the Centuries, the order is in its own column. An “evens” or “odds” note means the railroad assigned only the even or the odd numbers in that span.
