Rock Island Diesel Roster: All-Time

Last revised: October 19, 2026

By: Adam Burns

The Chicago, Rock Island & Pacific diesel fleet, counted once, is 1,029 locomotives. A renumber is the same locomotive. A rebuild is the same locomotive unless the builder gave it a new serial. Six of those new-serial rebuilds are in the total: U28B 254 and 261, GP40 360 and 361, and GP18m 1238 and 1239. The railroad those engines worked, from the charter of February 27, 1847, through directed service in 1980, is the Rock Island page. The steam locomotives are a separate roster.

Switchers

The switchers are 221 frames. Davenport built 30-ton and 44-ton engines, and two 112-tonners, 798 and 799. Whitcomb built five 44-tonners and, with the Canadian Locomotive Company, seventeen 75-tonners that came from Canadian National. Electro-Motive’s SW fleet of 1937 and 1938, numbers 500–528, is 29 locomotives. Those same frames were later rebuilt as SW900s and SW900m engines. The new numbers are not a second fleet. Alco’s switchers run from two S-1s and the HH900 demonstrator, No. 730, through the S-2s. Baldwin supplied VO-1000s, two S-12 demonstrators, and five S-8s. Lima-Hamilton built 800 and 801. The later Electro-Motive switchers are NW2s, SW8s, SW9s, SW1200s, and SW1500s, including SW1s from the Illinois Central and NW2s from the Pittsburgh & Lake Erie.

Slugs cut from switchers already in this table stay with those switchers. SW1 532 became slug 998, dedicated to the Silvis shop employees. SW1 544 became slug 999, named Pride of Armoudale. The two slugs that were new to the railroad, 282 and 283, are at the end of the roster.

Cab units

The cab units and boosters are 243 frames. Six TA diesels, 601–606, built in 1937, were the power for the first Rockets. The FT freight locomotives followed in 1944 and 1945. Numbers 83–93 and 83A–93A are printed as eleven cabs and eleven boosters, and each of those rows is also printed with only six serials. The count uses the eleven road numbers. The serial cells are blank. F2s, F7s, and ten FP7s, 402–411, filled out the covered-wagon fleet. Sixteen FA-1s and eight FB-1s, 145–160 and 145B–152B, were later rebuilt as FA-1m and FB-1m engines and renumbered into the 120s. Those are the same twenty-four frames.

Passenger cabs begin with the DL103b, two DL107s, and DL-109 621, which was repowered with an Electro-Motive engine and named Christine. E3s, E6s, E7s, and E8s followed, and E6A 627 was rebuilt as E8A 656 on the same frame. E6A 630 and E8A 652 are at the Manly Junction Railroad Museum. Two AB6s, 750 and 751, are E6B carbodies with one engine, a cab, and a steam generator. Three LWT-12s include the power car for the Jet Rocket. The railroad also bought nineteen F9Am and twelve F9Bm units from the Union Pacific. Those had not been Rock Island locomotives before, so they are in the count. F9Am 4158 was Union Pacific 522.

Road-switchers

The road-switchers are 557 frames. General Electric’s contribution is 39 U25Bs, 42 U28Bs, 25 U33Bs, and 18 U30Cs. The U28B total includes 262–281, twenty engines of late 1966, and two new-serial rebuilds, 254 and 261, from wrecked U25Bs. The U33Bs are 190–199, 285–289, and 290–299. Slug 282 was rebuilt from Seaboard Coast Line U33B 1719. U25Bs 201, 203, 210, and 222 became slugs and are still those U25Bs.

Electro-Motive’s Geeps are the largest share. The GP7s are 122 engines. Later GP7R and GP9R numbers assigned to those engines, and to the railroad’s own GP9s, are the same frames. Eight GP7Rs came from other railroads and are counted: 4429, 4430, 4471, 4472, and 4475–4478. Their serials were not printed. Number 4478 is ex-Precision National 1504, ex-Norfolk & Western 3471, built as Wabash 471. The GP9s in the table are 19. GP9m 1322 and 1331 are rebuilds of an F2A and an FTB and are not added. GP9 1332, serial 25356, is counted. A second note gives serial 23643 to a GP9m that it also numbers 1332. That serial is the one tied to F2A 41. 1332 stays one locomotive in this count.

GP18s are 21, plus two GP18m engines, 1238 and 1239, which received new serials after F-unit wrecks. GP35s are 34. GP40 360 and 361 are new-serial rebuilds of wrecked GP35s 306 and 310. The rest of the GP40s, including 4700–4719, bring that model to 77. GP40-2 numbers 3000–3006 are rebuilds of those GP40s, and 3005 and 3006 were marked incomplete. They are not new frames. The GP38-2s are 68, in three builder orders. Ten SD40-2s, order 73676, and five BL2s, five RS2s, thirty-five RS3s, fifteen RS1s, ten C415s, and two Fairbanks-Morse H15-44s complete the road-switchers. Four RS1s went to the Army as RSD-1s without new serials. RS3 463 was renumbered 475 after a wreck. It is still one locomotive.

Five Budd RDC-3s, 9000–9004, have no printed serials. The first diesel on the property was Alco-GE bi-power boxcab 10000, built in April 1930, Alco 68399 and General Electric 11232, one locomotive.
