The DE 2500 series from Henschel-BBC is a small series of three diesel-electric test locomotives. As the 202 series , they were used on a trial basis on the Deutsche Bundesbahn until the 1980s . Their specialty are the three-phase asynchronous traction motors , which are fed by a three-phase generator driven by a diesel engine. The locomotives have a modular structure and could be used on both two-axle and three-axle bogies (for routes with a lower permissible axle load). All three copies have been preserved.
commitment
The three machines have been tested in the 1970s by the German Federal Railways and regularly from Bw used Mannheim. Their DB designation was the 202 series with the company numbers
- 202 002-2 (white paint, later yellow at NS)
- 202 003-0 (red-orange paint)
- 202 004-8 (blue paint)
Due to the clear deviations from the color scheme of the Deutsche Bundesbahn, the vehicles were nicknamed "White Riese" (202 002-2, based on a detergent that was popular at the time) or later for the NS in yellow "Kanar" ("Canary Bird"). ), "Roter Ochse" (202 003-0) and "Blauer Bock" (202 004-8, based on a television broadcast on German television), more rarely also "Blauer Engel".
The 202 002-2 was converted into an electric locomotive with a pantograph for 1500 V direct current in the mid-1970s, painted yellow and tested by the Dutch Railways (NS) under the road number 1600P . During these tests, it was only equipped with a drive motor on one wheel set (axle order (1A1) 3 '). Because a decision in favor of locomotives of this type would have meant too long a delivery time, a locomotive derived from the French series BB 7200 was procured as series 1600/1800 of the NS.
After the return by the DB, at least one copy was temporarily rented to a private railway company.
Test vehicle "UmAn"
At the beginning of the 1980s, high-speed bogies with reversible drive mass ("UmAn") were tested on the 202 003. With them, the traction motors could either be coupled to the bogie frame or the main frame in order to gain knowledge for the drive technology at high speed. The locomotive was approved for speeds of up to 250 km / h, which it reached without any problems during test runs. For this purpose, the gear ratio was changed, at times the locomotive was given a provisional streamlined front section with windows from the 103 series on one side . In a top speed test on a roller dynamometer built by BBC in Munich-Freimann , even 310 km / h were measured. This copy is now in the German Museum of Technology in Berlin .
Influence on locomotive construction
From the point of view of the locomotive industry, which built the three copies at their own expense, the DE 2500 was primarily a test vehicle. Their technical and historical value is very high, because their design principles have largely shaped modern locomotive technology.
An immediate continuation of the series production was ruled out because the Deutsche Bundesbahn had a sufficient number of modern mainline diesel locomotives. However, it was incorporated into the design of the three-phase electric locomotives , initially in the 120 series . The drive technology of the UmAn locomotive with the flexible linkage of the axle bearings and the bogies by push-pull rods was used in the express train locomotives of the 101 series , as well as the InterCity Express multiple units InterCityExperimental (410 series), ICE 1 (401 series) and ICE 2 (series 402). Modern diesel locomotive series (for example Herkules and Traxx ) also use three-phase drive technology.
All locomotives have been preserved:
- 202 002-2: set up outdoors in front of the Bombardier Transportation plant in Kassel , the engine room was completely gutted and converted into a conference room
- 202 003-0: German Museum of Technology Berlin
- 202 004-8: Technoseum , Mannheim
