Diesel locomotives Type 411Da


    A single-cabin diesel-electric locomotive type 411 Da of 1200 HP designed for heavy-duty shunting service on marshalling and hump yards.
    On account of it's duty the locomotive is equipped with a large fuel tank ensuring some 7 days of operation without refuelling . The electrical system of the locomotive ensures high top speed of 80 km/h at full power of the diesel engine. This feature allows to use the locomotive for hauling goods trains on lines permitting 20 tons of load per axle.
    The constructions of the locomotive, fully meets the specific conditions of shunting work, i.e. frequent power adjustments, work under part loads, common motion direction changes, starting with high torque, etc.
    The locomotive may operate under ambient temperature from -25°C to +32°C, at altitudes up to 1000 m above  sea level at relative air humidity averaging 70%.
The underframe and sills are designed for mounting the automatic UIC coupling .
