Ringing True (14-16)
This resource, from Siemens, looks at the function of a wheel bearing on trains and the importance of finding out whether replacement is needed. Students consider the cost implications of replacing bearings before it is necessary and the cost and safety implications of not replacing them in time. Traditionally, wheels were tapped and the pitch of the note produced would indicate whether the wheel was worn. Students find out about the RailBAM system, which records the sound made by passing trains and compares it with the sound of a train with bearings in good working order. If there is a difference the system notes this and issues a warning.
