electromagnetic track brake
Quick Summary
An electromagnetic track brake is a type of friction brake controlled by an electromagnet. These brakes are used on some high-speed trains, such as Japan's Shinkansen train-sets, and are activated at the start of deceleration from high speeds. They work by lowering bar magnets into contact with the rails, generating frictional resistance to slow the train. Some systems use eddy current brakes instead of electromagnetic ones, which do not contact the rail but can generate strong electromagnetic fields.12
