New technologies such as the hybridization of satellite sensors for positioning will be used.
Adif has awarded Alstom a contract for the development of an ERTMS system project specifically intended for non-main railway lines, for an amount of 13.7 million euros. The contract includes the installation and testing of a pilot line of the General Interest Railway Network, specifically on the La Asunción Universidad-Guardo section, which is part of the León-Aranguren metric gauge line.

The objective of this R+D+i project, which will be carried out from the Alstom railway signaling and safety technology center in Madrid, is to develop a new application of the ERTMS standard for non-main lines, through the introduction of satellite technology, among others, for the positioning and use of public telecommunications networks. The initiative, a pioneer in Spain, proposes the use of innovative train positioning systems (through the use of sensor hybridization, including satellite ones) or the use of communication networks not based on the GSM-R standard (see news) .
The European Traffic Management System ERTMS is the most advanced train command and control system, adopted by the European Union, for signaling and communications between the track and the equipment on board the train.
Same security benefits
Less equipment on the road This European system for rail traffic management has contributed in recent decades to a safe and interoperable rail operation, widely deployed on international lines. However, its adoption in non-mainstreams has been more limited, due to its high cost and the difficulty of ensuring compatibility with already installed equipment.
This new system that is being sought to be developed now with this innovation project is characterized by having less equipment on the track, which will, however, equal the security benefits of the ERTMS usually implemented on high-speed lines. In addition, it will be an interoperable and homogeneous solution with the rest already in progress. In this way, secondary railway lines will be able to benefit from the advantages and functionalities of the European standard: ERTMS significantly improves the quality of the service and its features and conditions of reliability, quality and efficiency.
In addition, it increases the transport capacity of the system, by reducing the intervals between trains in circulation and reducing operating costs.
