The Baby Face is the cab Baldwin drew for its own road diesels before Hadley, Ryder & Pedersen redesigned the nose as the shark. The short version has a low nose and wide windshields. The long version is the Centipede, a 91-foot 2-D+D-2 with a rounded face of the same family. Railfans supplied the nickname. Baldwin’s catalog used the DR code.
Baldwin built 50 locomotives with the short cab, from November 19, 1946 (Jersey Central double-ender 2000) through December 30, 1948 (Missouri Pacific DR-4-4-1500s 204, 204B, and 208). That 50 is 33 DR-4-4-1500s, eight DR-6-4-1500s, two Gulf, Mobile & Ohio DR-6-4-2000s, six Jersey Central double-enders, and the Chicago & North Western’s single DR-6-2-1000. The Centipede is a separate count: 52 sold, and 54 on the builder’s serial list, completed from December 3, 1945, through July 20, 1948. By early 1948 Baldwin had stopped taking orders for the short cab. Units already booked were finished through the end of that year. The sharknose sold in larger numbers. Every locomotive that wore this cab went to scrap.

Electro-Motive’s E and F units were nearly a decade old when Baldwin put a catalog cab on the market. The E dated from 1937 and the F from 1939. Baldwin’s answer kept the idea of a streamlined cab and changed the face: a lower nose, and windshields wide enough that the crew sat behind a single pane of glass on each side. Railfans called it the Baby Face. On the Centipede the face is long and rounded. On the units in the tables below it is the short low nose. Both are Baldwin’s own cab, drawn before the sharknose commission.
The DR code reads the locomotive the way a Whyte classification reads a steam engine. DR is Diesel Road. The first number is every axle. The second number is the motored axles. The last number is the horsepower. A suffix tells the engines apart: /1 is one engine, and /2 is two. SC on the class string is the supercharged engine, and on the 608SC that blower is a Roots. NA is naturally aspirated. A DR-4-4-1500 is a road unit with four axles, four of them motored, at 1,500 horsepower. A DR-6-4-2000 has six axles, four motored, at 2,000 horsepower. A DR-6-2-1000 has six axles and only two motored, which is the North Western’s one-engine cab. The Centipede’s long form, DR-12-8-1500/2, is twelve axles, eight motored, and two engines of 1,500 horsepower. DR-12-8-3000 is the same locomotive written as one horsepower figure.
The freight cab was the model railroads actually bought in a set. Class DR-4-4-1500/1 SC, one 608SC at 625 rpm, 1,500 horsepower, B-B, 250,000 pounds. General Steel Castings swing-bolster trucks with drop-side equalizers, a 9-foot 10-inch truck wheelbase, and 42-inch wheels. Westinghouse supplied four 370F traction motors, a 471A main generator, and a YG42A auxiliary. Jersey Central, the New York Central, and the Missouri Pacific took the short-cab version: 22 cabs and 11 boosters, 33 locomotives, from November 11, 1947, through December 30, 1948.
Jersey Central’s first carbodies measured 53 feet 6 inches between coupler pulling faces. After that order Baldwin rearranged the equipment in the A units, and those measured 55 feet 6 inches. The B units stayed 53 feet 6 inches. Every short-cab DR-4-4-1500 left Eddystone on 15:63 gearing: 65 mph, and 42,800 pounds of continuous tractive effort at 10.5 mph. The catalog also offered 17:62, 19:60, 20:59, and 21:58.
| Gear ratio | Maximum speed (mph) | Continuous tractive effort (lb) | Speed at that rating (mph) |
|---|---|---|---|
| 15:63 | 65 | 42,800 | 10.5 |
| 17:62 | 75 | 37,200 | 12.2 |
| 19:60 | 82 | 32,200 | 14.0 |
| 20:59 | 87.5 | 30,000 | 15.0 |
| 21:58 | 93.5 | 28,100 | 16.0 |
Jersey Central took five A-B-A sets, cabs 70–79 and boosters K, L, M, R, and S. The New York Central took cabs 3400–3403 and boosters 3700–3701. Those four cabs later carried 3800–3803. The Missouri Pacific took four A-B-A sets, cabs 201–204 paired with boosters 201B–204B and with the second cabs 205–208. The Missouri Pacific units of December 30, 1948, are the last short Baby Face cabs Baldwin finished. Sharknose production of the same model began on February 28, 1949, with Pennsylvania 9568, and ran to 36 cabs and 36 boosters.

DR-4-4-1500 short cab, 33 locomotives. Baldwin serials run separately for cabs and boosters. Class DR-4-4-1500/1 SC.
The passenger model with one engine was built for two railroads, and for those two only. Class DR-6-4-1500/1 SC, one 608SC, 1,500 horsepower, A1A-A1A, 304,000 pounds. An A unit measured 61 feet between coupler pulling faces, and a B unit 59 feet 6 inches. The trucks were General Steel Castings rigid-bolster inside-equalizer frames, with a 13-foot 3-inch wheelbase and 42-inch wheels. The electrical gear matched the freight cab: four Westinghouse 370F motors, a 471A main generator, and a YG42A auxiliary.
The New York Central took cabs 3200–3202 and boosters 3300–3301, geared 22:57. That rating is 100 mph, with 26,400 pounds of continuous tractive effort at 23.5 mph. In 1955 the cabs became 3504–3506, class DCA-2A, and the boosters became 3602–3603, class DCB-2A. The Seaboard Air Line took cabs 2700–2702 and no boosters, geared 15:63. Eight locomotives, completed from November 22, 1947, through May 5, 1948. The Central’s three cabs and two boosters, and the Seaboard’s three cabs, are the production list. The New York Central diesel roster carries the 1955 numbers with the rest of that fleet.

DR-6-4-1500, 8 locomotives. Class DR-6-4-1500/1 SC. New York Central class after the 1955 renumber was DCA-2A on the cabs and DCB-2A on the boosters.
Jersey Central DR-4-4-1500 #71 leads an A-B-A set at Scranton, Pennsylvania, in January 1961. No. 71, construction 73115, was completed on November 11, 1947, in company with cab 70 and booster K. Richard Wallin photo.
The short Baby Face at 2,000 horsepower is two naturally aspirated 608NA engines, A1A-A1A, 80 feet between coupler pulling faces, and 375,000 pounds. Eight locomotives wore it: six Jersey Central double-enders and two single-cab units for the Gulf, Mobile & Ohio.
The first three were the first short Baby Face cabs. Class 0-6-6-0 1000/2, Baldwin serials NA6, NA7, and NA8, completed November 19, 1946, December 9, 1946, and February 14, 1947. A Baby Face cab stood at each end, so the locomotive could run either way. Jersey Central wanted that because the trains terminated at Communipaw Terminal on the Jersey City waterfront, where turning a cab unit was the problem the design was built to avoid. The railroad was in bankruptcy, and 2000–2002 were lettered for the subsidiary Wharton & Northern. Forty-inch wheels, 21:58 gearing, 93.5 mph, and 28,100 pounds of continuous tractive effort at 22.0 mph. Four Westinghouse 370F motors, a 480D main generator, and a YG40E auxiliary, on General Steel Castings swing-bolster trucks with a 15-foot 6-inch wheelbase.
The 1948 trio, 2003–2005, is the same double-ender reclassed DRX-6-4-2000. The X is the control-voltage change, from 125 volts to 75, to meet Association of American Railroads practice. The generators changed with it, to a 480F main and a YG42A auxiliary. Wheels went to 42 inches, and the gearing went to 15:63: 65 mph, and 42,800 pounds at 14.5 mph. All six are Baby Face at both ends.

Jersey Central double-enders, 6 locomotives. Baby Face cabs at both ends. Nos. 2000–2002 were lettered Wharton & Northern.
The Gulf, Mobile & Ohio’s pair is the single-cab version of the same machine: two 608NA engines, class 0-6-6-0 1000/2, 80 feet, 375,000 pounds, 40-inch wheels, and 21:58 gearing at the same 28,100 pounds and 93.5 mph. The main generator is a 480D. The auxiliary on these two is a YG40D. Baldwin assigned them to the Gulf Coast Rebel. No. 280 was completed January 4, 1947, construction 71580. No. 281 was completed February 12, 1947, construction 71581.
| Railroad | Road number | Baldwin serial | Construction number | Completed |
|---|---|---|---|---|
| Gulf, Mobile & Ohio | 280 | 1 | 71580 | 1/4/1947 |
| Gulf, Mobile & Ohio | 281 | 1 | 71581 | 2/12/1947 |
Gulf, Mobile & Ohio, 2 locomotives. Single-cab Baby Face.
The Chicago & North Western unit is a model of one. DR-6-2-1000 5000A carries one 606SC at 1,000 horsepower. The wheel arrangement is A1A-3: one three-axle truck with two traction motors, and one unpowered three-axle truck. The space a second engine would have occupied is a baggage compartment. The Chicago & North Western diesel roster carries it with the rest of that fleet.
| Railroad | Road number | Model | Construction number | Completed |
|---|---|---|---|---|
| Chicago & North Western | 5000A | DR-6-2-1000 | 73464 | 11/1948 |
DR-6-2-1000, 1 locomotive. One 606SC. A1A-3, with a baggage compartment where a second engine would have stood.
The Centipede came first. Seaboard Air Line 4500 was completed on December 3, 1945, and entered Jacksonville–St. Petersburg service on December 13. The catalog model is DR-12-8-1500/2, also written DR-12-8-3000: two 608SC engines, 3,000 horsepower, on a 2-D+D-2. Baldwin’s serial list runs to 54. Fifty-two were sold, 14 to the Seaboard, 14 to Ferrocarriles Nacionales de México, and 24 to the Pennsylvania. The last, NdeM 6413, was completed July 20, 1948. Two demonstrators from a cancelled Union Pacific order stayed on the builder’s account. The 1943 test bed is the same locomotive as Seaboard 4500, so it is already inside that count. The Centipede page has the specification sheets and the 54-line roster.

Baldwin’s 1945 passenger demonstrators, 2000 and 2001, carried a flat vertical nose of the same family as the export 0-6-6-0 1000/1. Each had two 8VO engines. Construction numbers 73020 and 73021, completed January 10 and March 28, 1945, classes 0-6-6-0 1000/2 DE1 and DE2. Ferrocarriles Nacionales de México bought them as 6000 and 6001, and in 1946 added 6002, construction 72671, completed August 30, with two 608NA engines and the same prow. The low-nose Baby Face, with the wide windshields, arrived the next year on Jersey Central double-ender 2000.
Orders for the short cab stayed with the six railroads above. Early in 1948 Baldwin sent the carbody to Hadley, Ryder & Pedersen. The firm designed the sharknose, arranged the interior equipment, and ran the stress analysis, working with Baldwin on the finished locomotive. The nose resembles the Pennsylvania Railroad’s T1 duplex, and that resemblance is where Raymond Loewy’s name became attached to the design. Hadley, Ryder & Pedersen drew it.
The Pennsylvania’s DR-6-4-2000s are the sharknose version of the 2,000-horsepower passenger cab: class BP20, two 606SC engines, 18 cabs numbered 5770–5787 and nine boosters, completed from June 17 through December 15, 1948. Those dates overlap the last short-cab deliveries. Sharknose DR-4-4-1500s then followed, 36 cabs and 36 boosters, beginning with Pennsylvania 9568 on February 28, 1949. The RF-16 was cataloged only in the sharknose. The sharknose page is that later cab. The Pennsylvania units sit on the Pennsylvania diesel roster.
The 608SC was a difficult engine in railroad service, and the short Baby Face cabs had short careers. Jersey Central was still running DR-4-4-1500s in the mid-1960s. The Scranton photograph on this page is January 1961, and sister units were still on that railroad’s freights in 1964 and 1965. By the end of the decade the short-cab fleet had been retired. The Centipede’s own service, including the Mexican units that ran into 1971, is on the Centipede page. The carbodies on this page were scrapped. The two Baldwin cabs that survive are RF-16 sharks, on the Escanaba & Lake Superior.
