New articulated trolleybuses for Arnheim

Connexxion is expanding their emission-free public transport operation in the Dutch city of Arnheim using 18 metre articulated trolleybuses. The vehicles from Carosserie Hess will be equipped with the proven traction equipment from Vossloh Kiepe.

Arnheim, the only city in the Netherlands with a trolleybus network, is once again putting their trust in
Vossloh Kiepe. The public transport company of Arnhem Oostnet Group N.V. have already ordered
traction electronics from Vossloh Kiepe starting in 1990. Currently the public transport company is being
operated by Connexxion, who also placed this particular order.

Together with Carosserie Hess, Vossloh will supply Arnheim this time with nine 18-metre articulated
trolleybuses with an option of nine additional buses. The delivery is scheduled to begin in September
2009 and should be finished by November 2009.

Carosserie Hess’ successful Swiss Trolley III was chosen as the vehicle type for this order, and is
furnished with the innovative traction technology by Vossloh Kiepe.
The buses have a two-axle drive: two engines drive two of three axles. This guarantees good
acceleration and secure electric braking with a high rate of energy recovery. The power consumption of
these articulated buses was optimised with the aid of Vossloh Kiepe’s energy management. The internal
auxiliary load or other vehicles driven by the network can be supplied by the brake energy recovered.
The newly developed OSA 500 current collector system from Vossloh Kiepe provides a high safety
standard during operation. It is possible to raise the current collector poles to and lower them from the
overhead line with the press of a button from the driver’s compartment. The modular system enables the
fastest reaction times via the usage of a pressure-controlled remote sensing system.

Connexxion has additionally decided to use the Vossloh Kiepe SDH System Diagnostics Help. The
system is capable of compiling and transmitting the diagnostics and status data of the new vehicle fleet
while it is in operation and of transmitting it to a stationary database.

The incoming statuses are categorised so that the operator always receives the current status while the
vehicles are still in active operation, thus maintenance operations can be planned when necessary.
