In the field of railway transport, car is used to power vehicles. A moving car can be a locomotive or emu traction unit. Autorail Grande Capacite (AGC) in AGC wheel and transmission of FAG bearing 2007 Bombardier Transportation make 500 AGC for its new high-speed train. According to the requirement of the French national railway, AGC because its model range and meet the demand of the French region. That is to say, can only provide AGC diesel or electric drive, also can be in combination. Also can through to two to four carriages coupling to change capacity. The adoption of modular design (i.e., using the same components), although the model is more, maintenance and service is very simple. AGC provides drivers with more flexibility, more short stop, provides more space and comfort for passengers. FAG provides out-of-the-box to all AGC model of tapered roller bearing and axle box. The design requirements of modern railway vehicles provide a high degree of passenger comfort, low noise and fuel economy. Applied in railway transmission system of the rolling bearing in the industrial sector development schaeffler group this possible. All kinds of ball and roller bearings are used in shaft guide. As described below, can use such as deep groove ball bearing, spherical roller bearings, angular contact ball bearings and various types of bearings.

Railway transportation sector's growing demand for control and monitoring systems, requires a comprehensive data collection vehicles at run time. More and more wheel bearing the demand of the information used for various vehicle system. Including speed, direction, monitoring signal, and the bearing temperature monitoring as an additional function of thermal control running. Schaeffler group industrial sector developed with integrated sensor (with integrated sensor is installed modules) of wheel bearing, the product has been optimized to meet the requirements of railway transportation. Sensor pass information about speed reliably to wheel slip and braking system, speed indicator, door closed institutions and rolling identification system. Hot run early recognition of continuous temperature measuring potential problems can be found as early as possible, in order to have enough time to take appropriate measures. In the future, as the basic maintenance by additional sensor signals, such as vibration signal and operating performance, on the basis of continuous access to information. Train control system in the future such as ERTMS/ETCS or other train control system, the bearing can to a large number of independent multi-channel speed system.
