s between 1945 and 1948. The series comprised eight individual versions, all of which sold only in small numbers; across all versions, only 39 locomotives were produced. Each version was produced only for a single railroad. Many shared the same Baldwin model number, DR-6-4-2000, even though they were rather different; this was because the Baldwin model only encoded the total axles (6), the driven axles (4) and the power output ().

Baldwin demonstrators

The first produced version comprised a pair of DR-6-4-2000 demonstrators built in 1945. This, unlike later models, used Baldwin's Inline-8 8VO engine model. These locomotives had a unique cab that featured the same upright, aggressive prow as the 30 Baldwin 0-6-6-0-1000/1DE C-C units built on a U.S. Army order in June 1945 for shipment to the Soviet Railways as part of a Lend-Lease. They emerged as Baldwin #2000 and #2001, with #2000 built in January and #2001 built in March. After demonstrating on the

ordered six DRX-6-4-2000 locomotives for its then-subsidiary Wharton and Northern, #2000–#2005, which were unusual for North American diesel locomotives in that they had driving cabs at both ends. The first three #2000-2002 had the cab doors on the same level as the locomotive frame and were delivered with an orange roof. The last three had their doors on the cab floor level and were delivered with a dark blue roof. On the CNJ they were known as "Double-enders". The cab style was nicknamed "Babyface" and was used by several other Baldwin models. The original paint scheme was a deep, rich blue on the lower part of the locomotive and tangerine on the upper part. Almost all were retired around 1962–63, but #2004 was kept as a stationary heater in

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.
