Network Rail is currently rolling out a new digital Railway Communications System (RCS) across Britain’s rail network. This will allow direct, continuous and secure communication between train driver and signaller, which will considerably improve safety, reliability and punctuality for all passengers. RCS is replacing the existing legacy system, Cab Secure Radio (CSR), which is outdated, does not provide the required coverage and is becoming increasingly more expensive to maintain. This new network is solely for the delivery of the Railway Communications System and will not be used by commercial mobile telecoms operators. In order to implement the new system, around 2,200 railway communications masts are required, one of which is needed near Croxley Green and one near Chorleywood station to provide 100% coverage on this section of the Chilterns line. The siting of any communications mast is sensitive. Before a site is selected they consider a number of factors:
Over recent months Network Rail has been investigating a number of possible locations for the railway communications masts and equipment cabins in the area. During this time they have held a meeting with planning officers at Three Rivers Council about these proposals. Following this and after a number of site investigations they have identified two sites that fit their criteria. These are: Croxley Green: just west of the intersection of the Chilterns line and Grand Union canal a 20m lattice mast is proposed.
