ERTMS
With speeds above 160 km/hour, but certainly at 300 km/hour, a train must be in perfect shape. The high speeds make it impossible for the pilot, as the engine driver of a high-speed train is called, to read the signals along the track, such as a red light. For this reason, the signal masts on the HSL route are replaced by a computer-controlled cabin signal system based on radio communication: GSM for railways (GSM-R).
Via GSM-R the pilot of a high-speed train is constantly receiving section information on his onboard computer. Purpose-built, interconnected management and safety systems will be monitoring the train's speed and check if the next section of the track can be accessed. Everything that is happening in front of and behind the train will be immediately visible in the cabin. If necessary, the system will intervene automatically.
The ultra-modern, advanced safety system of the HSL complies with the latest European standards: the European Rail Traffic Management System (ERTMS). ERTMS is the collection of European specifications in the area of train management, safety and communications in railway transport. It will be the undisputed European standard for a new, universal system to make trains and the railway track safe. Thanks to this standard, all train safety systems in the European network of high-speed lines will be perfectly attuned. This makes it possible for the high speed train to continue its route in all participating countries. The HSL will be the first line to use ERTMS across national borders.
Connections to existing tracks
The Dutch high-speed line not only connects to Belgium, but it also connects in five places to existing, regular tracks: at Breda, Zevenbergschen Hoek, Rotterdam Lombardijen, Rotterdam North and Hoofddorp. In these locations, both the regular trains and the high-speed trains will be using the same sections of the track. In these sections, the existing safety systems (EBS) and ERTMS will have to be connected to each other. As the moment, the regular safety system is 'translated' into ERMTS when a high-speed train approaches.
