A repeater signal preserved at St Albans. These were used where visibility was limited, such as on a bend where there was a danger that without this advance warning a train might not see a signal at "danger until it was too late to stop. Date August 2018. Photo courtesy Rosie Bayliff. |
A preserved Midland Railway wooden post lower quadrant home signal. This example has a pressed steel signal arm, whereas earlier signal arms were made of wood. The "White Diamond" on the signal post indicates that the track which the approaching train is using is fitted with a track circuit, which indicates to the signalman there is a train on the line. Unfortunately this was found necessary following crashes where a signalman forgot about a train standing at a signal and set the signals clear for a subsequent train. An advantage of the track circuit for the loco crew was that they could safely remain with their loco, instead of walking to the signalbox to report their train was standing a signal (in accordance with Rule 55 in the rule book) Date August 2018.
