Canadian Pacific Diesel Locomotives: History, Roster & Photos

Published: September 17, 2026

Canadian Pacific tried diesel in the yard in the late 1930s and did not finish the job until November 6, 1960. The first true road units were Electro-Motive E8As 1800–1802, 2,250 horsepower, La Grange, 1949—the same year Montreal delivered the last Selkirk. GMD FP7s and MLW FA-2s did the everyday passenger and freight work. The last steam-hauled train was a CRHA extra, 4-4-0 29, Montreal to St. Lin.

Number series follow builder records as compiled by The Diesel Shop (revised July 27, 2026), Extra 2200 South, Canadian Trackside Guide, and the CP diesel archive at trainweb.us/galt-stn. Information compiled September 16, 2026.

Switchers first, then three E8s

CP put a diesel in the yard in 1937. Production switchers followed in 1943: Alco S-2s, Baldwin DS-4-4-1000s, later GMD SW8s, SW9s, SW900s, and the SW1200RS road-switcher that became a Canadian trademark. Road freight and passenger still belonged to G3s and Selkirks. In 1949 Electro-Motive delivered three E8As, 1800–1802, A1A-A1A, 2,250 horsepower, the only E-units on the railroad. They were oddities beside GMD F-units and MLW FAs. #1800 at Ottawa in 1968 is that trio still at work, nineteen years on. 1800 and 1802 later went to VIA.

Canadian Pacific E8A 1800 with its train at Ottawa Ontario November 1968

Canadian Pacific E8A #1800, one of three the railroad rostered, stopped with its train in Ottawa, Ontario, November 1968. Author’s collection.

The same years brought Alco and MLW FA-1s and FB-1s in the 4000s and 4400s, then FA-2s. #4093 at Côte Saint-Luc on the company page is that 244-engine fleet in 1970, a year before most of the FAs were stored. GMD F7Bs and F9Bs filled out the booster end. First-generation road paint was maroon and grey with script lettering. The Multimark—the Pac-Man diamond—arrived with the 1968 CP Rail reorganization and lasted into the 1980s.

Passenger cabs: FP7, FP9, RDC

The Canadian of April 24, 1955, wanted steam-generator cabs. GMD delivered FP7As in the 1400s (1951–53) and FP9As 1405–1415, with F7B and F9B boosters. They handled Montreal–Vancouver, the Atlantic, and the eastern corridor until VIA took the trains on October 29, 1978. FP7 #1424 at Hull and FP9 #1410 at Dorval stay on the company page with the train. CLC built Fairbanks-Morse C-Liners for freight (CFA16-4) and a handful of Train Masters. Budd RDCs covered the locals the steam Ten-Wheelers had given up: Toronto–Buffalo, Montreal–Ottawa, Sudbury–White River.

A few FP9s came back decades later for the Royal Canadian Pacific and office specials—ex-CN/VIA cars in CP paint, 1401, 4106, 4107. They are tourist and business power, not a second passenger fleet.

Alco, Montreal, and the C424

Montreal Locomotive Works was CP’s other store. RS-2s, RS-3s, RS-10s, RS-18s, and RS-23s did four-axle freight and transfer. RS10 #8470 at Sunnyside, on the company page, is that fleet. One six-motor oddity, RSD-17 8921 of 1957, was a demonstrator CP kept—the only RSD-17. S-3, S-10, and S-13 switchers filled the yards.

When the 244-powered FAs wore out, CP traded cores to MLW for C424s, the four-axle Century: about fifty-one to fifty-four units in the 4200s, 1963–66. #4201 at St. Luc in March 1970 is the class at home. The publicity C424s in the Spiral Tunnels stay on the company page. Six-motor MLW power followed: C630M, M630, M636, and a single M640, 4744, 4,000 horsepower, 1971. Those 251 engines did not last into the Dash-9 years. GMD Geeps and SD40s took the main line.

SD40, SD40-2, and the Red Barn

GMD SD40s in the 5500s (1966–71) were the first high-horsepower six-motor standard. Then came the SD40-2, the locomotive that dieselized the Selkirks for a generation: original CP numbers in the 5565–6092 range, hundreds of units, 1972–84, plus Soo and later secondhand blocks. In 1988 GMD built twenty-five cowl SD40-2Fs, 9000–9024, unique to CP, nicknamed Red Barns. A handful later ran on Central Maine & Quebec and came home.

Four-axle second-generation power was the GP38-2. Parent GMD units filled 3021–3135. Soo GP38-2s became CP 4400s; Milwaukee GP38-2s the 4500s; D&H GP38-2s the 7300s.

General Electric, ECO rebuilds, SD70ACu

CP’s modern road fleet is General Electric six-motors. AC4400CWs arrived from 1995 in the 8500s, 8600s, 9500s, 9700s, and 9800s. From 2017 many were rebuilt as AC4400CWMs and renumbered into the 8000s and 8100s. ES44ACs filled 8700–8960 (2005–11) and 9350–9379 (2012). EMD’s late new six-motors were SD90MAC / SD9043MAC units in the 9100s, 1998–99. Those cores became the SD70ACu 7000s at Progress Rail in 2019–20: 7000–7059 plus 6644. 7010–7014 left the shop in script heritage; 7015–7019 in serif heritage; 7020–7024 in military commemorative colors, including Desert Sand #7021 in the Buffalo photograph.

Ogden and EMD also rebuilt first- and second-generation power to EPA rules. GP20C-ECOs 2200–2329 came from GP9 cores, 2012–14. SD30C-ECOs 5000–5049 came from SD40-2 cores, 2012–16, new crashworthy cabs, 12-710 engines, 3,000 horsepower. #5036 at Sedan, Minnesota, in 2019 is that program on the old Soo/Milwaukee map.

Current power (2026 snapshot)

Heavy road power in 2026 is still a CP-numbered GE fleet under CPKC paint: AC4400CWM 8000s/8100s/8200s, remaining AC4400CWs, ES44ACs 8700s and 9350s, and new ET44ACs in the 7400s. EMD’s contribution is the SD70ACu 7000s, leftover SD40-2s, SD30C-ECOs, GP38-2s, and GP20C-ECOs. Progress Rail has SD70ACe-T4s 5500–5564 on order. Treat any single current number as a snapshot. The present-tense railroad is CPKC.

All-time roster (by builder)

This is an owned-and-lettered parent-CP diesel roster by model and original number series, not a serial-by-serial card for every unit CP ever ran. Quantities are builder production for CP unless noted. Renumberings and rebuild programs are in the notes. Soo, D&H, Milwaukee, DM&E, and Kansas City Southern diesels stay on those company pages; inherited blocks appear here as notes.
