Enyse to upgrade Spain’s heaviest-duty traffic corridor

Adif has awarded Enyse with the contract for the renewal of the Signalling system of the North-East zone of Madrid’s commuter network. The project includes the sections Atocha-Guadalajara and San Fernando de Henares-Hortaleza.

The existing relay interlockings will be replaced with new EiSS23 electronic interlocking at 11 stations, also controlling the corresponding blocks. New Jointless Track Circuits will be installed as well as new wayside signals connected to the national ASFA ATP system. The line will be controlled from Chamartín’s CTC. On the Telecoms side, a new backbone FO cable will be laid, locating the centralized supervision equipment and telephones at San Fernando. An operation telephone system will also be deployed along CCTV, Access Control and Anti-intrusion systems.

Security and Protection aspects will be managed from the relevant CPS Centers at Madrid and Delicias, where immediate attention is paid to alerts thru the activation of the resources called for any emergency – whether medical, firefight, police… This territorial CPS management is coordinated with the H24 Network Center, which commands all Security and Protection functions. The project includes the supply of power for all systems above, new technical equipment rooms and a Centralized Maintenance System at the CTC.

The Henares corridor is currently under intense railway operation, so maximum Safety guarantees will be provided for train movement – following the guidelines stated at the exploitation programme defined by Adif’s Traffic Management Division. Utilizing a range of tracks departing from Atocha’s South side, the corridor provides services for the C2, C7 and C8 commuter lines of public operator Renfe, along Main Line passenger and freight trains. Railway logistic services at the Henares corridor have been in constant rise since the 60’s, including the Coslada and Azuqueca dry ports, the Meco depot and other industrial yards with railway facilities. The freight terminals of Torrejón de Ardoz and Vicálvaro are also serviced from what today is the heaviest-duty traffic corridor in Spain.
