GMV has been selected by Renfe to provide the system that will monitor the instantaneous speed of the train in real time, alerting the driver if it does not meet the allowed values, both on the current section as in the next ones. The project, called internally “navigation system as reinforcement of signaling systems” is an evolution of a first pilot study conducted by GMV on the Madrid – Albacete project. The design of this system arises in the wake of the fatal accident in Angrois in July 2013. Based on the instantaneous velocity and other parameters such as the type of train and braking curve, this system is able to calculate the braking distance required for the train to reduce its speed to a value acceptable in the next section of the railtrack.

To calculate the current position on the raltrack, the system combines information obtained from an integrated high sensitivity GPS receiver with the train’s own odometer, thus enabling the use in tunnels and areas of no GPS coverage. The system consists of one of GMV’s standard OBUs (R-M20), connected to a touch terminal on the desk of the train, which will show all the travel information and travel plans to the driver, as well as the necessary warnings well in advance, should the train be required to slow down. The system also mounts a speaker that will issue an audible warning in the cab depending on the level of importance of the message. Additionally, the system includes a maintenance module which allows to download the records containing, among others, the maximum speed excesses detected through an application that will also allow detailed analysis of all data stored by the system.

The current scope of this project includes the 44 trains that make the 130 and 730 Renfe series, which make the journey Albacete – Alicante, although it is expected that in the future be extended to other Renfe lines and trains.
