As the railway developed, it became apparent that a signalling system was required.
Currently, two signal boxes control train movements around the railway and communicate with each other using a traditional bell code and block instrument system.
The railway is fully signalled with semaphore, disk and colour light signals. The main lines are fully track circuited, enabling the signalman to monitor train progress on bespoke track diagrams when trains are out of visual range.
On normal running days, the signalling system can be set to automatic, enabling the railway to run without a signalman present. Sprung points are used to allow trains to run a normal circuit around the railway safely, being controlled by automatically resetting signals. Up to eight trains can run at any one time when the signal boxes are open.
