Introduction

A railway radio communication system for operational train control, enabling information exchange between Rollingstock drivers and operational dispatch personnel at control centers, station and crossing duty officers, drivers of oncoming and following trains, and other personnel involved in train operations. Portable radios are installed in the driver's cab, while stationary radios are located in the duty officer's offices [1].

For example, the Swedish Transport Administration (Wiki banner.png)’s radio system GSM-R (Wiki banner.png) follows European standards. The system has been specially adapted for the railway. The map service shows which lines have access to the GSM-R (Wiki banner.png) network [2].

For one of <line> sections of Trafikverket (link to the railML® website)'s <network> the modeling of <trainRadio> can look like this: 

        <trainRadio id="trR01" radioSystem="GSM-R">
          <areaLocation id="trR01_lloc01" >
            <associatedNetElement netElementRef="ne_a11">
