1962-63, but #2004 was kept as a stationary heater in Jersey City until mid-1968. GM&O locomotives The Gulf, Mobile and Ohio Railroad ordered two locomotives in 1947, road #280 and #281, with #280 built in January and #281 in February. These were delivered in a single-ended "babyface" carbody. They mostly pulled the Gulf Coast Rebel streamlined train from St. Louis, Missouri to Mobile, Alabama as a pair. Both were retired in October 1958, and scrapped in June 1965. NdeM locomotive The Ferrocarriles Nacionales de México ordered one additional DR-6-4-2000 unit in August 1946 after purchasing the two demonstrators. This was assigned road #6002 and had nearly identical styling to the demonstrators, but used two 608NA engines instead of their VO power plants. It was scrapped in September 1957. 606SC-engined DR-6-4-2000 locomotives These were produced exclusively for the Pennsylvania Railroad and were delivered in 1948 in the sharknose body style designed by Raymond Loewy, as diesel running mates to the T1 steam locomotive; also built by Baldwin and similarly styled by Loewy. Eighteen A units and nine B units were produced, producing nine three-unit locomotive sets of . The PRR classified them as BP-20 (Baldwin Passenger, ). They were originally used on top-flight express trains such as the Broadway Limited, but problems soon relegated them to lesser service. They ended their days on commuter trains along the New York and Long Branch in New Jersey. A small number were de-rated for use in freight service (re-classified as BF16z). DR-6-2-1000 A single DR-6-2-1000 locomotive of A1A-3 wheel arrangement was produced for the Chicago and North Western Railway in November 1948 and assigned road #5000A. This contained only a single Inline-6 606SC engine of ; the rear engine compartment was replaced by a baggage compartment as it hauled mostly local trains. It was retired in January 1958. Other locomotive units like this included the Chicago, Rock Island and Pacific Railroad's EMC AB6 in their original form. 608SC-engined DR-6-4-1500 locomotives Baldwin also built “Babyface” A1A-A1A units with a single 608SC engine of . Seven cab-equipped locomotives were built—four for the New York Central Railroad (#3200–3203), and three for the Seaboard Air Line Railroad (#2700–2702). Two cabless boosters were also built, both for the New York Central (#3210–3211). The New York Central units rode the same long wheelbase General Steel Casting Trimount trucks as the larger units (and various ALCO passenger units), an excellent high
