In the field of railway transportation, bullet trains are vehicles used to provide power.A bullet train may be a traction unit of a locomotive or an EMU.

In 2007, Bombardier Transportation produced 500 AGC Capacite trains for SNCF.According to the requirements of SNCF,AGC meets the regional needs of France due to its wide range of models.This means that the AGC can be supplied with internal combustion or electric drive only, or with a combination of internal electricity.Capacity can also be varied by linking two or four cars together.Due to the modular design (that is, using the same parts), maintenance and service are very simple despite the large number of models.AGC provides more flexibility for drivers, shorter stops, and more movement space and comfort for passengers

 

FAG supplies ready-to-use tapered roller FAG bearings and axle boxes for all AGC models.Modern rail vehicles are designed to provide a high level of passenger comfort, low noise and economy.This was made possible by rolling bearings developed by the Schaeffler Group Industrial Division for use in railway driveline systems.Various ball and roller bearings are used in the guide of the drive shaft.As described below, many types of bearings such as deep groove ball bearings, self-aligning roller bearings and angular contact ball bearings can be used.

 

The increasing demand for control and monitoring systems in railway transport requires comprehensive data collection during the operation of the vehicle.An increasing number of wheelset bearing information is used for the needs of various vehicle systems.It includes speed signal, direction monitoring, and bearing temperature monitoring as an additional function of thermal operation monitoring.Wheelset bearings with integrated sensors (ready-to-install modules with integrated sensors), developed by the Schaeffler Group Industry, have been optimized to meet the requirements of rail transport.Sensors reliably transmit speed information to wheel sliding and braking systems, speed indicators, door closing mechanisms, and rolling recognition systems.Early thermal operation identification of continuous temperature.
