GSM-R user procedures (cab radio Version 2) 1 Introduction A new digital radio communications system is being introduced to the railways of Great Britain. This uses a version of GSM (global system for mobile communications) - the system used by mobile-phone companies. The GSM-R system has been specifically developed for European rail companies. It is based on European standards and specifications. The idea is to make sure trains can travel freely from one country to another.
GSM-R user procedures (cab radio Version 2) 1.3 Definitions Call routing Cell-based call routing: A way of making calls to people who are registered based on where the caller is, for example, calls will be routed to the nominated signaller, operations controller or ECO. Cell-based routing uses information based on which cell the caller is within the GSM-R network to route the call.
GSM-R user procedures (cab radio Version 2) Lead driver The lead driver has lead responsibility in conversations with other drivers registered on the same train. Communication with anyone else concerning the movement of the train will normally be handled by the lead driver.
GSM-R user procedures (cab radio Version 2) 2 The GSM-R systems GSM-R is based on the same technology that is used for public GSM (mobile phone) networks. However there are some extras added for railways. The GSM-R system is made up of a network of radio base stations installed at the side of the track at regular intervals (about every five or six kilometres depending on the local environment and so on). These provide radio coverage for the cab radio and people using the GSM-R mobile system.

GSM-R user procedures (cab radio Version 2) 2.2 GSM-R call types There are two generic types of call in GSM-R - point-to-point calls and group calls. Within each of these types of call there are a number of variants as listed in Table 1. Generally, in the case of the cab radio, taking part in a group call involves using the press to talk (PTT) button to speak to the other people involved in the conversation whereas taking part in a point-to-point call does not.
GSM-R user procedures (cab radio Version 2) The signaller (or operations controller) will announce, at the beginning of the recording, that the message is a broadcast call and will ensure that the end of the recording is clearly identified. This will make late entrants or those leaving the pre-defined broadcast area aware that they have received only part of the broadcast call. The cab radio automatically answers broadcast calls and speech is relayed through the loudspeaker.
GSM-R user procedures (cab radio Version 2) 2.5 Call routing The GSM-R network uses a series of base stations located alongside the railway to provide radio coverage. The coverage associated with each base station is commonly known as a cell area. In most instances each cell will have only one signaller. In these instances the GSM-R network can route any calls or operational text messages sent from a cab radio to the correct signaller.
GSM-R user procedures (cab radio Version 2) The person with ‘Lead Responsibility’ will be responsible for re-establishing communication, for example, in the case of a communication involving a signaller and driver, the signaller would be responsible for re-establishing the communication. If you are not the person with ‘Lead Responsibility’, then you must wait to be contacted by the person with ‘Lead Responsibility’. 2.
GSM-R user procedures (cab radio Version 2) 3 GSM-R system users The main purpose of GSM-R is to provide secure communications between train drivers and signallers. However, the following people are also likely to use the system: Signal box supervisors. Network Rail operations controllers. Electrical control operators (ECO). Train operator controllers. Guards. Other on-train staff. Shunters. Trackside workers.
GSM-R user procedures (cab radio Version 2) Figure 2 – GSM-R fixed terminal 3.1.2 On-train equipment The GSM-R equipment installed in the driving cab includes a cab radio assembly, user interface, handset and cradle, cab loudspeaker, roof-mounted antenna and associated cabling. The cab radio may also have its own battery to maintain power in case the normal power supply is interrupted. The separate user interface (display unit) has a display and push buttons and is linked to a handset and loudspeaker.
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 routeby-route basis, it is therefore likely that there will be gaps in coverage until the network has been fully rolled out. 4.
GSM-R user procedures (cab radio Version 2) registered with the GSM-R network at the changeover point so that it is on the signaller’s fixed terminal list of trains and mobiles. When operating in an IVRS radio area, and where authorised, the GSM-R cab radio can be used for communication in place of the IVRS handset. When changing between radios, it is essential that the driver checks the operational status of the radio.
GSM-R user procedures (cab radio Version 2) An alternative method has been developed to avoid a driver having to dial the long form 8digit number. This is achieved by dialling a short code 12nn (the value of ‘nn’ will be allocated on a location specific basis to allow the call to be directed to the correct signaller). A sign (see Figure 8) will be provided on affected signals displaying the correct signaller’s GSM-R short code number, to tell drivers about this.
GSM-R user procedures (cab radio Version 2) 5 Overview of the GSM-R cab radio This section provides an overview of the GSM-R cab radio and what it does.
GSM-R user procedures (cab radio Version 2) 5.1 Cab radio buttons and what they do Button name Number Button to What it does Used to enter numbers and alpha digits when registering, onto the display. Also used to enter text when searching the phonebooks. Accept Used to answer calls and accept user entry. Cancel Used to reject or end a call and cancel user entry. Press it once to delete the last character entered or hold it down to clear all the characters entered. Menu Provides access to the menu.
GSM-R user procedures (cab radio Version 2) 5.2 GSM-R cab radio display-screen layouts The cab radio display contains four lines each with 20 characters and has four different screen layouts depending on how you are using the radio. The display modes are: normal mode; shunting mode; menu layout; and list layout. 5.2.1 Normal-mode layout The normal layout and associated fields are shown below (the dotted lines are only to show the boundaries between the fields and you will not see these on the display).
GSM-R user procedures (cab radio Version 2) 5.2.3 List-display layout When displaying a list, the screen will be arranged as shown below. The phonebook is an example of a listed layout where entries are displayed in alphabetical order, which you can go through using the scroll buttons or using the ‘list search’ field by entering up to the first three characters to find a particular entry. The list item you have chosen will be identified by a cursor to the left of the item.
GSM-R user procedures (cab radio Version 2) bottom right-hand corner of the display, shows that there are other entries in the current menu. Using the menu, scroll and accept buttons, to get to the pre-registration function is shown below as an example. Press to get to the top-level menu. 1 Calls... 2 Shunt Mode 3 Settings... 4 Reg/De-reg... Use to move the cursor down to item 4 (Register or deregister). Press to choose item 4. The cursor in the sub menu will automatically go to item 1 (pre-register).

GSM-R user procedures (cab radio Version 2) 6 Entering service 6.1 Preparing the cab radio Before a train enters service, you must check the operational status of any cab radio that is to be used during the journey. This is normally the responsibility of the person who is carrying out train-preparation duties. 6.1.1 Traction unit power on Whenever the traction unit is cut in the cab radio will also power up and automatically test itself.
GSM-R user procedures (cab radio Version 2) Once switched on the GB GSM-R network name will be displayed (“GSM-R GB”), showing that the cab radio has connected to the GSM-R network. If the cab radio does not find network coverage, for example, due to a local network problem or in an area not yet operating with GSM-R, the display will show ‘Searching networks, Please wait’. GSM-R GB Searching networks Please wait If the cab radio does not find coverage at all refer to section 9.2.6.
GSM-R user procedures (cab radio Version 2) not, you must deregister the TRN that is displayed and register the correct train TRN for your journey (see section 6.2.1) provided to you by your company. Registration retained by the previous driver. GSM-R GB 1A26 Ensure that the train reporting number (headcode) is correct for your journey. 6.1.4 User adjustable cab radio settings The cab radio has pre-defined volume and brightness levels set already, you can change these when using the cab radio.
GSM-R user procedures (cab radio Version 2) In either case, use the appropriate button to increase or reduce the volume. The volume setting bar will change (as does the audible volume, if the relevant audio path is open). If you are in a call, simply pressing the up and down buttons will change the relevant volume control. If you do not make a change within a two-second period, the volume control will be cleared from the display and the current setting will apply.
GSM-R user procedures (cab radio Version 2) If it is not possible to register the cab radio then you may need to revert to an alternative secure method of communication for the passing or receiving of operational instructions, as shown in the rule book. If it is not possible to register the cab radio then there is a risk of voice calls and operational text messages being routed to the wrong signaller.
GSM-R user procedures (cab radio Version 2) In signal assisted call routing areas there is normally only one train describer berth associated with each signal section and it will always contain the TRN of the first train scheduled to depart. Therefore if you are the driver of the second train and you attempt to register the cab radio before the first train has departed, you will block the first train’s registration.
GSM-R user procedures (cab radio Version 2) When you have successfully registered, you will hear a tone and the train reporting number will be displayed. GSM-R GB 1A45 You must make sure that the train reporting number displayed is correct for the journey. If you do not have the TRN, for example the train is not a pre-planned move; you can get the number from the signaller.
GSM-R user procedures (cab radio Version 2) While the cab radio is outside the GSM-R coverage area, the display will show that it is searching for the network. Searching networks Please wait Pressing at the point that you need to register within the GSM-R coverage area will begin the registration process. It will send the registration identity to the GSM-R network.
GSM-R user procedures (cab radio Version 2) Once you have removed the driving key, the cab radio will offer you the option to keep the registration (see section 6.4), for example, if you change ends on a locomotive. If you do not take any action, it will lead to automatic deregistration after 10 seconds. Or, press to deregister the cab radio immediately. GSM-R GB 1A45 Deregistering...
GSM-R user procedures (cab radio Version 2) 6.4 Keeping registration There might be times when you want to keep the registration, for example, when changing ends on a locomotive or temporarily vacating the cab. Under these circumstances you will still decommission the driving cab in the normal way by removing the driver’s key, however, when prompted, you have 10 seconds to keep the registration by simply pressing . This will keep the cab radio registered for 30 minutes.
GSM-R user procedures (cab radio Version 2) 6.6 Using phonebooks 6.6.1 Phonebook dialling The design of the cab radio includes a Network Rail phonebook which can store up to 1200 phone numbers. The numbers are those of Network Rail signallers, operations controllers and Electrical Control Operators. The actual numbers are not listed but instead the names of the locations, for example, Yoker West. This gives access to every fixed terminal GSM-R phone number in the country.
GSM-R user procedures (cab radio Version 2) Once you have pressed the first digit the ‘Connect to?’ message is displayed. Enter all digits using the keypad in this example the full 8-digit fixed terminal phone number. GSM-R GB Connected to? 1A45 74100001 To make the call press . Once the call is connected, the name of the person you are calling will replace the dialled number on the display (if the number is found in the phonebook).
GSM-R user procedures (cab radio Version 2) 7 Using the cab radio to communicate These procedures must be used alongside the rule book. You must always use GSM-R as the normal radio system if it is available for use. That is, if a GSM-R cab radio has been fitted and commissioned in the cab of the train, and the route for your journey is covered by GSM-R as indicated in the sectional appendix and by line side signs. 7.
GSM-R user procedures (cab radio Version 2) 7.1.2 Receiving an urgent point-to-point call There may be times when the signaller needs to communicate urgently with you, but the circumstances do not warrant the use of a railway emergency group call. The urgent point-to-point call allows the signaller to contact you quickly, as the priority of the call will automatically end an ongoing call you may be in which has a lower priority, such as a normal point-to-point call.
GSM-R user procedures (cab radio Version 2) Phase 1 - the warning All cab radio users in the emergency group call area will hear an alarm and see a warning on the display, even if the radio has not yet been registered. When you receive a railway emergency group call, the cab radio will let you know with an audible alarm message “Emergency, Emergency, Emergency” and the message ‘STOP EMERGENCY’.
GSM-R user procedures (cab radio Version 2) this case, at the end of the short confirmation tone you will hear a ‘busy’ tone and see the message ‘busy’ on the cab radio display. Holding down the PTT until the other user releases their PTT will not work. You have to release your PTT and press it again when you see the “PTT” prompt. Railway emergency group calls made by the signaller will be announced with the following message: “This is a railway emergency call.
GSM-R user procedures (cab radio Version 2) Wait until the railway emergency group call has ended and contact the signaller using a point to point call. Do Not move your train until you have received enough information to determine that your train is not affected by the emergency. 7.1.3.
GSM-R user procedures (cab radio Version 2) You must listen to the message being announced and, if necessary, pass on the information to other onboard members of staff or passengers on the train. A broadcast call is normally a pre-recorded announcement and might be joined (or left) by the cab radio part-way through if the train enters/exits the group call area. As a result, the start and end of the message will be as described above to allow you to know whether the entire message has been received.
GSM-R user procedures (cab radio Version 2) The simplest way to make a point-to-point call is to press the call signaller button . However, in some areas it cannot be guaranteed that the call will be routed to the correct signaller. In these areas, signal box phone number signs or short code ‘12nn’ signs (see section 4.4) give you a direct-dial number to the controlling signaller. You can also look up the signaller in the menu phonebook (see section 6.6.
GSM-R user procedures (cab radio Version 2) If the call failed to connect then a ‘failed to connect’ tone (same as unobtainable tone), will be played and message displayed. 7.3.3 GSM-R GB 1A26 Failed to connect Calling a signal box that has closed If a signal box closes on a line still open to traffic, the signaller in another signal box will normally take over the communication role of that box. In these circumstances you must communicate with the adjacent signaller.
GSM-R user procedures (cab radio Version 2) When the signaller answers the call, the display will change to show the call is connected. GSM-R GB 1A26 Connected Urgent Salisbury Panel 1 If the number you are calling is busy, or the call fails for any reason you will hear an appropriate tone instead of the ringing tone and the display will show the same messages as those for the point-to-point call (section 7.3.1). 7.3.
GSM-R user procedures (cab radio Version 2) The cab radio shows that the railway emergency group voice call has been made and the red button ‘flashes’. GSM-R GB Calling Once the call is made, you will hear an emergency annunciated warning tone from the loudspeaker for five seconds (“Connecting emergency group”, when connected use press to talk). You should not start to communicate until the warning tone ends and you see the message PTT.
GSM-R user procedures (cab radio Version 2) If the call cannot be made the cab radio will try again for up to 30 seconds. GSM-R GB Retrying 1A26 Emergency Group If the call is not connected after 30 seconds the display shows the following: GSM-R GB 1A26 Failed to connect Emergency Group If the railway emergency group call fails to connect you must use an alternative method of communication to contact the signaller. 7.3.
GSM-R user procedures (cab radio Version 2) However, in most circumstances your initial point of contact will be the signaller responsible for controlling the area where you are, so where necessary, you must arrange for the signaller to speak to the ECO on your behalf. 7.3.10 The ECO may be listed twice in the phonebook, firstly under the name of the control room, for example Cathcart ECO, and secondly under ‘ECR’.
GSM-R user procedures (cab radio Version 2) Option 2 – uses the “Multiparty call” function in the menu. The following text shows you how to set up driver to driver communication using both options. Note: Driver to Driver communications is the only procedure which requires an eight digit registration code You and the other driver involved will need the following information: Five digit code for the combined train formation.
GSM-R user procedures (cab radio Version 2) Once you have chosen Driver 2 you must GSM-R GB Registering press to begin the registration process and send the registration identity to the GSM-R network. 12345159 Driver 2 Registration now follows the same process as described in section 6.2.3. Both registered cab radios should then display the correct TRN (headcode).
GSM-R user procedures (cab radio Version 2) Once the Lead Driver ends the call to the signaller, the cab radio will automatically retrieve the held call (Driver 2) and the two drivers can then use the GSM-R system to communicate. RSSB The cab radio allows the receiving party to replace the handset on its cradle and operate in ‘hands-free mode’.
GSM-R user procedures (cab radio Version 2) Option 2 – Using the Multiparty Call function Driver 1. The driver who has lead responsibility for communicating with the signaller must obtain the 99x wildcard location code and the five digit journey code from the signaller. This driver can then register through the menu using the agreed five digit registration and the three digit wildcard location code. Use , , , or by choosing the menu items you need using the scroll buttons.
GSM-R user procedures (cab radio Version 2) Once you have chosen Driver 2 you must press to begin the registration process and send the registration identity to the GSM-R network. Select: 1 Lead Driver 2 Driver 2 3 Driver 3 -- 1A51 GSM-R GB When registered this display will show Dv2 To connect the two radios together, the Lead Driver makes a Multiparty call by selecting ‘Build Multiparty’ from the ‘Calls’, ‘Other Calls’ menu. Only the Lead Driver can initiate this call.

GSM-R user procedures (cab radio Version 2) 7.4 Handling several calls (call holding, call waiting, call pre-emption) You may put an existing call on hold to make another call or to answer another incoming call. 7.4.1 You have the option to put a point-to-point call on hold to answer another incoming call. However, an incoming call of a higher priority may be answered automatically, which will end an ongoing call (pre-emption).
GSM-R user procedures (cab radio Version 2) GSM-R GB When you are retrieved by another party the display will inform you the call is being retrieved. The display will show for five seconds only.
GSM-R user procedures (cab radio Version 2) 7.4.3 Reconnecting a held call When retrieving a call that you have put on hold you must identify yourself again to the other user. To retrieve a call that is on hold, choose ‘Retrieve Call’ from the main menu press , 7.4.4 .
GSM-R user procedures (cab radio Version 2) 7.5 Sending operational text messages 7.5.1 Standing at signal You must normally use the standing at signal operational text message to remind the signaller about the presence of your train when standing at a signal at danger. The cab radio allows you to do this by simply pressing the button. You must only use this function at signals not displaying a fixed terminal 8-digit number or 12nn short code number (see 4.4).
GSM-R user procedures (cab radio Version 2) 7.5.1.2 Signaller calls driver The signaller could make a point-to-point voice call to you, to pass specific information, for example, authority to pass the signal at danger. 7.5.1.3 GSM-R GB Incoming call 1A26 Salisbury panel 1 Signaller clears signal The signaller could clear the signal. In this case you will not receive any further communication. Press 7.5.1.4 to clear the display of the ‘standing at signal’ message.
GSM-R user procedures (cab radio Version 2) The total duration between releasing the DSD and the alarm being sent is 1 minute; this is the same as existing CSR radios. If transmission of the DSD alarm message fails, the cab radio will try again up to two times after which time an appropriate failure message will be displayed. GSM-R GB Failed 1A26 DSD Alarm After receiving the DSD alarm message the signaller is likely to respond by making an urgent point-to-point call to your train.
GSM-R user procedures (cab radio Version 2) 8 Shunting mode 8.1 Introduction Shunting mode is a particular mode of operation where the GSM-R cab radio communicates direct with other GSM-R radios operating in shunting mode by using special group calls. There are no applications of Shunting Mode available in the UK at this time; hence this mode is not yet covered by these User Procedures.
GSM-R user procedures (cab radio Version 2) 9 Trouble-shooting guide This section describes the action that you can take to identify and overcome possible problems associated with the GSM-R cab radio. 9.1 Losing the main power supply (back-up battery arrangements) If the main power supply to the traction unit is interrupted, for any reason, the cab radio can continue to operate from the vehicle batteries.
GSM-R user procedures (cab radio Version 2) 9.2 If the radio does not power up correctly 9.2.1 Power-up self-test failures If the cab radio fails the power-up self-test, you will see a failure message. We split failures into service affecting and non-service affecting. 9.2.2 Service-affecting failures Service-affecting failures are shown as a ‘Radio failure’ followed by a number which identifies the type of failure to the maintainer.
GSM-R user procedures (cab radio Version 2) the cab radio will attempt to reboot five minutes after displaying the failure. It is permissible to manually re-boot the radio (when safe to do so), to attempt to clear the fault. These types of faults must be reported. If attempting a manual re-boot by tripping and re-setting the cab mobile circuit breaker; if a battery back up is fitted, the drivers control panel must be switched off first.
GSM-R user procedures (cab radio Version 2) 9.3 9.3.1 Registration problems Registration failure If the message ‘registration failed’ is displayed after trying to register the cab radio, you should check the registration code was entered correctly by attempting to register the cab radio for a second time. GSM-R GB Registration failed 1A45 990 Lead Driver If you are still unable to register the cab radio then you must contact the signaller.
GSM-R user procedures (cab radio Version 2) 9.3.4 The signaller may be able to clarify that the PA is shown on the fixed terminal and will therefore be able to call the PA. Wrong train reporting number displayed If the train TRN displayed on the cab radio is not correct, deregister this number and try registering again, with the same code. If this still returns an incorrect TRN, you must deregister the TRN and contact the signaller controlling the movement of your train for advice.
GSM-R user procedures (cab radio Version 2) will lead to a registration failure when coverage is regained as the train may no longer be at that signal. Pending registration is not available when you register through the menu. Press on the cab radio. Then press to attempt to send the registration code to the GSM-R network. If GSM-R network coverage is not available, the cab radio will automatically store the registration code.
GSM-R user procedures (cab radio Version 2) 9.4 The radio will attempt to de-register the stuck registration when the drivers control panel is re-activated. Temporary loss of coverage Although the GSM-R system provides full coverage of the rail network, there may be times when there is a temporary break in coverage, for example a base station fault. There will be a warning tone sounded through the loudspeaker and a message ‘searching networks please wait’ on the display.
GSM-R user procedures (cab radio Version 2) signaller by dialling the signaller’s number, 12nn number, phonebook, sectional appendix or periodic operating notices (PON). 9.6 Under such circumstances calls will be routed to the nominated signaller who may not be the controlling signaller and hence appear to be ‘misrouted’. Always check the display to be sure which signaller has answered the call, and report any instances of ‘misrouted’ calls.
GSM-R user procedures (cab radio Version 2) At the end of the self-test, you will see the results. Test complete Test ok The ‘Test OK’ message will automatically be deleted from the display after five seconds..If the test fails, a message ‘Test failed’ will be shown together with a list of the failed test details. These will be indicated as described in section 9.2.1. If any of the tests are considered fatal (shown as “Failure”).
GSM-R user procedures (cab radio Version 2) 9.8.2.3 Option 3 - loudspeaker test The loudspeaker test allows you to test the cab radio’s loudspeaker. Once you have chosen the loudspeaker test, you will hear a tone through the loudspeaker. You can cancel the test by pressing tone ends. 9.8.2.
GSM-R user procedures (cab radio Version 2) a) Red Button Test Once you have chosen the ‘red button test’, the display changes to show that the test may begin and you are asked to press the ‘Emergency’ button. 1A51 Red button test Press red button You have up to 30 seconds in which to press the button or the test will fail. If the cab radio detects that the ‘railwayemergency group voice call’ button has been pressed, the display will change to ask you to release it.
GSM-R user procedures (cab radio Version 2) You have up to 30 seconds in which to release the button or the test will fail. If the cab radio detects that the ‘urgent priority’ call button has been released then ‘Test OK’ will be displayed. If not a failure message is displayed.
GSM-R user procedures (cab radio Version 2) 9.8.2.5 Option 5 - Attached systems test This test allows you to test the link to all attached systems, for example, an OTDR. Once you have chosen the attached systems test, the cab radio tests the connection with all attached systems. Other DCP Testing link If the test is successful, a ‘Link OK’ message is displayed for two seconds and then the next system is tested.
GSM-R user procedures (cab radio Version 2) 9.8.2.6 Option 6- PA Tests The PA speech test allows you to test the train’s PA system. Two sub menu options are available: a) PA Tone Test This test sets up a repeating tone to allow all PA speakers in the train to be tested by walking through the train without the need for a second person. This test is used by maintenance personnel.
GSM-R user procedures (cab radio Version 2) You cannot delete these service affecting failure messages, as the cab radio can no longer be used. You must report all service affecting failures to the signaller and act on the instructions that you are given. If the “Radio Failure 01” appears the radio will automatically re-boot after five minutes to try and clear the fault.
