Track circuit indicator
Track circuit indicator for Box T. Located on model railway layout, gauge 1, Lancashire & Yorkshire Railway Signalling School, built 1912, by L&YR.
The indicator shows the location of a train at a specified (track circuited) section. A low electrical current passed through the rails is short-circuited by the train’s wheels, thus trigering the repeaters indication to change from 'track clear' to 'track occupied'. This indicator shows status of the track circuit TC1 on the L&Y layout.
