Can you tell me more about the incident?Â
Thameslink have been advised of a problem with the signalling system which is causing delays to services between St Albans and Sutton. To reduce delays some services have been removed.Â
The fault is with the Axle counters. An axle counter is a system used in railway signalling to detect the clear or occupied status of a section of track between two points. The system generally consists of a wheel sensor (one for each end of the section) and an evaluation unit for counting the axles of the train both into and out of the section. They are often used to replace a track circuit.Â
The drivers will pass the signal and proceed at a speed slow enough that they may stop short of any obstruction. This will cause delays to each service which means fewer services than normal can run.
