3072, Diesel-hydraulic locomotive "V 100" "Br 212"

The 3072 locomotive was purchased in August 2013.

The conversion of this locomotive with Marklin mfx conversion set (item 60924) is not officially supported. Conversion needs modifications to locomotive metal body.

The V 100 (later marked as 211 and 212) is a multi-purpose diesel locomotive with a working weight of 63.2 tons and a length of over 12 m (39ft. 4"). The new types develop about 1000 kW, and this power is transmitted by means of cardan shafts to the 4 axles arranged in 2 trucks.

To suit the tractive force of the powerful motor to the requirements of passenger and freight traffic, a two speed gearbox is used. The gear ratio must be selected when the locomotive is stationary. In low gear the locomotive exerts its maximum speed of only 65 km/h (40 mph), while in high gear it reaches 100km/h (62 mph).
