GSM-R user procedures (cab radio Version 2)

4 Where GSM-R works

The aim is that GSM-R should cover the whole of the rail network in Great Britain including

tunnels and cuttings. The network will be introduced in stages over a number of years. As

a result, it will be extended over a period of time. The network will be provided on a route-

by-route basis, it is therefore likely that there will be gaps in coverage until the network has

been fully rolled out.

4.1 Identifying GSM-R areas

The beginning and end points of GSM-R operational areas are identified using the

following signs.

The sign shown opposite (Figure 4) shows the start

of a GSM-R radio section and potential changeover

point from cab secure radio (CSR) or national radio

network (NRN) radio to GSM-R.

When a train passes one of these signs, the driver

must check that the GSM-R radio is working

registered and connected to the GSM-R GB

network.

Figure 4 – Start of GSM-R area

The top half of the sign shown opposite (Figure 5)

shows the end of a GSM-R radio section. When

reaching the end of a GSM-R section, drivers will

have to change to another radio system, for

example NRN. To help with the changeover from

GSM-R to NRN or CSR, the NRN or CSR code is

also displayed on the lower half of the sign.

4.2 Changing between different radio systems

Drivers can change from GSM-R to NRN while the train is moving, as long as they can do

it safely and without causing distraction.

Drivers must not change from GSM-R to CSR while a train is moving, as they need to pay

more attention to this process.

Drivers can change from CSR or NRN to GSM-R on the move when the GSM-R cab radio

has been pre-registered (see section 6.2.4), the driver must confirm that the cab radio has
