In order to test this entirely new rail system under realistic conditions a test track on a reduced scale of 1:2.5 was commissioned at the University of Paderborn in 2003. It is 530 m long, boasts a section with an ascending slope of 5.3 % and has a passive track switch, thus allowing in-depth checks and comprehensive trials of strategies for forming and dissolving convoys. Operation of the RailCab vehicles gives impressive proof of the technical feasibility of the whole concept.
To date two test vehicles have been built. Each of them is 3.4 m long and 1.2 m both high and wide, its weight being 1.2 tn. On the test track the vehicles can be operated at a maximim speed of 10 m/s.
The test vehicles on the scale of 1:2.5 already comprise all essential function modules of the future series-produced RailCabs. So every test-RailCab has two single-axle running-gear boxes with individual wheel sets, two suspension/tilt modules, and two secondary elements of the doubly-fed linear-motor drive. For test operation it is also equipped with a multitude of sensors and data-processing devices.
