Request for curve friendly running gear is not a new tendency. But, the combination with other requirements is challenging again and again, among them are increased top speed, minimized maintenance costs, and standardised vehicle concepts. Bombardier drafted, designed and realized the Passive Radial Steering (PRS), based on long experience in the development of mechatronic running gear (esp. with the Active Radial Steering ARS), as a cost-efficient solution for new vehicles as wells as for retrofits.

Mechatronics has entered the level of application in bogies of standard railway vehicles. Based on experience from approx. 20 years of development, as well as on a self-developed me-chatronical kit-set, Bombardier supplies vehicles of different kind with mechatronical applications, which are configured out of a set of standard components. Some of the functionalities are tilting, active suspension and condition monitoring for the bogies. But this is only the top of the iceberg. The future is a wide, complex evaluation of the collected data which enables additional functionalities, like the monitoring of the track con-ditions as an add-on. [ABSTRACT FROM AUTHOR]
