DWA ET 2000 TT
The ET 2000 TT is the prototype of a multiple unit that was built in just one copy. Its original name was RE 2000.
history
The vehicle was built in 1996/1997 in the test department of Waggonbau Halle, at that time a DWA plant. The tests took place in 1997/1998 at the Halle-Ammendorf plant and the Deutsche Bahn plant in Dessau-Süd.
In 1998 the multiple unit was towed to the north avenue of the Hanover Fair , where it demonstrated the functionality of the tilting technology while standing for the duration of the event. The train was visited by the then chairman of the Deutsche Bahn board, Johannes Ludewig, and the then Prime Minister of Lower Saxony , Gerhard Schröder . Since Deutsche Waggonbau AG (DWA) was taken over by Bombardier Transportation in early 1998, most of the advertising was removed from the vehicle before the Hanover Fair.
The only non-towed trip took place as a promotional trip with invited people on May 29, 1998, starting from Dessau's main train station towards the north.
The ET 2000 TT was mentioned in the 1997 Deutsche Bahn environmental report.
After the Hanover Fair in 1998, the “ET 2000 TT” project was scaled back because Bombardier was not interested in the project. In the following years, the unique item was parked on the site of the former manufacturer AEG, now Bombardier, where it was left to the weather and heavily sprayed with graffiti. At the beginning of 2018 it was acquired by a private person who had it towed to the Meyenburg train station and later to the Plau am See train station . There it was lifted onto a single track.
Technology and equipment
The vehicle has single-axle drives and tilting technology . In contrast to ICE models, the latter was already electronically controlled right up to the pantograph and implemented via hydraulics . For this purpose there were two gyro compasses from armaments technology. The outer skin consists largely of solid- colored carbon fiber reinforced plastic (CFRP); CFRP was also planned for a later center piece at these points. The interior, especially the seats, were designed by the students of an art college based in Halle (Saale) . The expansion of the interior was only partially completed. The transformer, the oil cooling of which was prepared for possible heating of the passenger compartment, was manufactured by ABB . The hydraulics were from Mannesmann / Rexroth . The electronics for the tilting technology came from the Technologiezentrum Nord (TZN), the rest from the CE Plus and the electrical equipment from FAGA Berlin, which also ensured that the control circuits for each part of the car were galvanically separated from each other.
