Roller Rig with experimental Bogie for independently rotating Wheels

To develop a new control technology for railway vehicle bogies with independently rotating wheels instead of wheelsets, a test environment was set up in which an experimental 1:5 scale running gear is driven on a roller rig. This allows different sensor and controller concepts for actively influencing the lateral position of a wheel pair with respect to the track center to be analysed and compared in terms of their suitability.
