Diesel Electric Locomotive. Dutch State Railways (NS) class 6400. With DELTA electronic circuit. Special motor with bell-shaped armature and flywheel. 4 axles powered. 4 traction tires. Metal handrails and end platforms. Coupler pockets can be replaced with front skirting. Length over buffers 16.5 cm (6-1/2").
This locomotive was produced as a one-time series only in 2000.
The Dutch State Railways ordered a totally new diesel locomotive from the Kiel Machine Company (MaK) for the modernization of non-electrified motive power. It was based on the DE 1002 in use on several privately owned railroads in Germany and made use of electrical components from the development of the class 120 electric locomotive.
The almost 1,200 kilowatt (approximately 1,609 horsepower) output required of the electronically controlled, three-phase asynchronous motors demanded a larger motor and fuel tank. This made the locomotive over 1.5 meters (4 feet 11-1/6") longer. The exhaust was installed off-center for better visibility down the track. Many other design detail changes were necessary, until the NS class 6400 resulted from the DE 1002 standard locomotive.
120 units of this class were in use, most of them in the NS classic gray/yellow paint scheme. After the freight service in the Netherlands was privatized and separated into groups, the last units were painted in the red color scheme for NS Cargo.
