In an important milestone, the diesel-hybrid version of the
will be the first trams-trains with this traction system to
operate in Germany. While the electrical versions to be supplied
for city center rely on traditional traction technology, the
hybrid tram-trains represent a true departure. They are designed
to operate on both the electrified tracks of city center and the
non-electrified tracks of suburbs, when they rely on their
diesel-electric traction. This traction technology will allow
passengers to circulate in and around the Kassel region without
having to change trains. The Regio CITADIS will provide a
seamless connection between inner-city tramway lines and suburban
railway networks.

ALSTOM will supply low-floor, three-car trainsets in two

  • 18 bi-current vehicles (600/750 Volt DC and 15 kV 16 2/3 Hz
  • 10 diesel-hybrid vehicles (600/750 Volt DC and
    diesel-electric traction).

Basic vehicle information 

  • Length: 37 meters  
  • Floor height: 70% low-floor (areas between
  • Passenger capacity: 220 total, including 92
  • Speed: up to 100 km/h.

The vehicles will be designed and built by ALSTOM's unit in
Germany. The electric traction system will be supplied by the
company's unit in

In selecting ALSTOM from strong international competition,
the customer cited the companys widely recognized
competence as a systems supplier, 'less interfaces result in
synergies having a positive influence on the delivery period and
the overall price.'

Delivery of the vehicles will begin between the end of 2003
and the beginning of 2004, with the first 8 electric vehicles.
The remaining 10 electric vehicles as well as the 10
diesel-hybrid vehicles will be delivered in the course of

Technical Highlights

Benefits of the two-system tram-train with variable
traction system
ALSTOMs innovative two-system train concept is based
on similarly designed vehicles equipped with different traction
packages: for bi-current operations (electric for tram lines as
well as electrified railway lines) and for diesel-hybrid
operation (electric for tram lines and diesel-electric for
railway lines). The two-system vehicles are able to run both on
the urban tramway and on the suburban railway network, saving
costs by using existing infrastructures. The similar design of
the vehicle fleet leads to advantageous economic maintenance and
repair for the transport authority.

Roof-mounted diesel motors permit low-floor areas
A further advantage is the mounting of the motor aggregates
on the roof. This innovation enlarges the underfloor area of the
vehicle and makes possible the low floor area between passenger
doors. This design concept has already been successfully used in
the LIREX, a regional motor unit prototype developed by
ALSTOM, which will start its regular commercial operation in
Saxony Anhalt at the end of 2002.

Comfortable and passenger-friendly
The vehicle design focuses on passenger comfort. Spacious
multi-purpose areas between doors of end cars leave room for
prams, bicycles, luggage and wheelchairs. Each vehicle side is
provided with a specially developed foldable ramp allowing easy
access for the mobility-impaired. As only end cars are equipped
with entrance doors, the intermediate car becomes a room for
relaxing. Here, passengers can enjoy increased seating comfort
and make use of numerous luggage racks. All cars have
