What can a small magnet do? For Western Railway (WR), it can help improve the efficiency of local trains. Authorities have been fitting Auxiliary Warning System (AWS) inductors that can send information about the status of a signal to the motorman electromagnetically in advance, allowing him to increase or decrease the speed of the train, on all tracks between Churchgate and Virar. Sources in WR said that they have installed around 70 additional inductors on the entire stretch.

Track magnets help motormen increase or decrease the speed of the train based on the information received about the status of the signal, well in advance. File pic for representation
