The Albtal-Verkehrs-Gesellschaft mbH (AVG) and the Verkehrsbetriebe Karlsruhe GmbH (VBK) ordered 30 dual-system tram-trains from Bombardier in September 2009.
The FLEXITY Swift vehicles are customized to meet the requirements of the city and the region of Karlsruhe. For an optimum fit to the existing infrastructure all access areas are 50% low-floor thus ensuring a rapid passenger flow and facilitating easy access for the mobility-impaired as well as passengers traveling with prams or heavy luggage. The new vehicles consist of 3 modules enabling barrier-free movement. The 37 meter long light rail vehicles with a width of 2.65 meters offer a capacity for 244 passengers. Conventional bogies with air springs guarantee a smooth ride reducing wear and tear of both wheels and tracks to an absolute minimum.
