DB Class V 90
The DB Class V90 (after 1968 the DB Class 290) locomotive is a German diesel-hydraulic locomotive for shunting and freight hauling.
The DB Class V90 locomotives are similar to DB Class V 100 (Class 211 & 212) locomotives, they stemmed from a need for a heavy shunting locomotive - it was originally planned to create a heavy shunting variant of the V 100 (ballasted and with reinforced frame) to be produced, but this did not come to pass due to the design's stability problems.
Maschinenbau Kiel in co-operation with BZA München designed a longer and heavier locomotive, of a completely new design. In 1964, a pilot production of 20 of these were manufactured with a 1,100 horsepower (820 kW) engine as used in the DB Class V100.1 and a 70 km/h top speed.
In 1974 the first locomotive of the main production was produced - these locomotives had the 1,350 horsepower (1,010 kW) engine used in the DB Class V100.2 and a top speed of 80 km/h (50 mph). The locomotive length was also extended to 14.32 m (47 ft 0 in). By 1974 408 had been built by MaK, Deutz, Henschel and Jung.
The machines have both a Dead-man's vigilance device (German:Sifa) and "Inductive train control system" (German:Indusi) (see Punktförmige Zugbeeinflussung) safety devices.
The locomotives were originally deep red (RAL 3004), in the mid-1970s a new ivory / ocean blue (RAL 5020 - RAL 1014) colour scheme was introduced, in the second half of the 1980s an eastern red (RAL 3031) color scheme was used and since the late 1990s, the locomotives are found in the current traffic (RAL 3020) red of Deutsche Bahn AG.
Since 2003, the locomotives have been upgraded with a new 1,100 kW (1,500 hp) engine (type 8V 4000 R41 MTU) equipped, as well as other components being upgraded (specifically the hydraulic drive). The modernised locos save fuel despite having a higher rated engine. The serial number of the remotored locomotives is increased by 500 (e.g. 290 030 becomes 290 530).
One locomotive of the class was procured by the Army for use in an Air Force supply regiment in Mechernich and given the locomotive code 290 999; on loan from the Deutsche Bundesbahn.
