Farnham Re-Signalling

The scope of the Farnham re-signalling project involved the de-commissioning of three signal boxes at Farnham, Aldershot and Ash Vale that transferred control to a new panel at Woking Area Signalling Centre. The works involved the re-control of existing trackside equipment at Aldershot, Ash Vale and Farnham using computer based technology.

The platform at Bentley Station was extended to allow 5 car trains to stop and to allow all door opening for passengers, with Bentley Loop being extended by 270m which now allows two trains to pass each other simultaneously. The scheme also included the full renewal & re-control of Farnham Level Crossing CCTV and the transfer of control to Woking Area Signalling Centre. Alterations were also made to the road layout in order to improve local safety concerns.

The scope also included the recovery of the existing train detection system and this was replaced with frequency based track circuits which are more reliable and require less maintenance. The above changes resulted in a more reliable infrastructure for running trains and has increased train punctuality.

RTIS supported Atkins on this project with skilled signalling teams for a period in excessive of 9,500 man hours. There were no reported accidents and RTIS were highly praised for their efforts and contribution, particularly on the commissioning works which were held over a period of 8 days in August 2013.
