Desiro HC – a good start for the new platform
with the Rhine-Ruhr Express
Siemens Traction Transformers, one of the world’s leading
suppliers of traction transformers and throttles, received
an order to manufacture and deliver traction transformers
for 83 trains for Rhine-Ruhr Express (RRX) to launch the
new Desiro HC platform. The new, exceptionally efficient
regional trains are each equipped with two single-deck
end cars and two double-deck middle cars and are used
only for passenger service. The 105-meter trains can seat
approximately 400 people. Siemens Traction Transformers
has thus secured an opportunity to be represented with its
transformers in future projects involving this platform for
regional service.
The first Desiro HC transformer is scheduled to ship in
January 2017. The complete series will be manufactured
in the Nuremberg factory and will ship by 2020.
RRX, which is considered to be the metropolitan area’s
project of the century, is expected to mitigate the growing
traffic problems in the Rhine-Ruhr region starting in 2018.
The region is one of Europe’s largest urban population
centers, with around ten million inhabitants and numerous transit routes. Overloaded mass transit and train
connections have significantly limited mobility for years,
especially on the main route between Cologne and
Dortmund.
Like the train design as a whole, the transformer’s technical design is based on components that must meet the
highest standards of energy efficiency. Two transformers
with four traction windings each are installed on the roofs
of the two end cars of each train. The train’s lightweight
construction and, not least, the transformer’s aerodynamic design both help reduce the total energy consumption.
Dr. Berthold Sedlmaier, CEO of Traction Transformers,
comments on the contract award: “Our transformer was
developed specifically to meet the requirements of the
new generation of regional trains, the Desiro HC in this
case. There is even room for improvement if necessary,
for example where energy efficiency is concerned.”
