Project Information:

Signals tell the train driver when it is safe to continue ahead. Renewal and maintenance of this equipment may be required to replace old signalling equipment or to improve the positioning of the signals. This allows more efficient use of that area of the railway network, thus trains will run safely and reliably. This may also permit more trains to operate and/or allow faster journey times.
