What is the difference between GSM and GSM-R?
In general, GSM-R uses characteristics that are identical or similar to those of the GSM system, such as frequency spacing (200 kHz), modulation (Gaussian minimum shift keying, GMSK) and access type (TDMA, TDD/FDD). The frequencies of GSM-R are extended below the frequencies of the GSM-900 standard.
What is a GSM-R mast?
GSM-R is a secure platform for voice and data communication between railway operational staff, including drivers, dispatchers, shunting team members, train engineers, and station controllers.
Why GSM-R?
The Global System for Mobile Communications-Railway (GSM-R) delivers digital, secure and dependable communications between drivers and signallers. This helps to increase safety, reduce delays and improve performance – providing a better experience for passengers.
Do trains have radios?
Radios are used for communication between train dispatchers and locomotive engineers, train dispatchers and MOW crews, and MOW workers and signal maintainers.
What radios do trains use?
Most railroads use a set of 97 frequencies between 160 and 162 MHz. Most operations are in “Conventional/Analog” mode, that means they do not usually use trunking, digital or other complicated modes. Most railfans will want to have a handheld scanner that you can use while standing line side.
Do trains use computers?
Computers and microprocessors have found many other uses as a railroad management aid. For example, daily data on each locomotive’s mileage and any special attention it has needed can be fed by its operating depot into a central computer banking historical data on every locomotive operated by the railroad.

How can you tell if a train is coming?
If a signal is lit up and shows all red lights, it is possible that there is a train approaching from “behind” the signal as shown in the photo above. If a signal is lit and shows a green light at the top, that means it is cleared for a train to approach from the lit/facing side, so a train may be coming.
How to make the GSM-R system successful?
Your input is essential to making the GSM-R System successful. Refer to the signaller guide “The Rule Book” Don’t interpose too late. Know your local arrangement with drivers Check digits.
What is ERTMS/GSM-R?
Through its working groups, the ERTMS/GSM-R project brings together existing and future implementers of GSM-R, assisting the former in realising their objectives and keeping the latter – and the railway industry in general – informed of developments.
What should I do if I make a mistake on GSM-R?
Spurious REC calls – mistakes happen. Talk to the signaller to let them know what has happened Report any issues to the signaller Your input is essential to making the GSM-R System successful. Refer to the signaller guide “The Rule Book” Don’t interpose too late.
What does mi and m mean in GSM-R?
The complete set of Mandatory for Interoperability (MI) and Mandatory for the System (M) must be complied with together in order to ensure a viable working GSM-R system. Following that, this split in two categories does not apply for non-European implementations.
