Invensys Dimetronic has won a Euro 3.5 million contract to modify the ASFA national railways network train protection system currently in use on the Madrid-Seville high-speed line signalling system.

The original signalling system was installed in 1992 and now Spanish infrastructure administrator ADIF wants to adapt the operational rules and functional aspects of the existing interlockings to bring them in line with more modern ones being used on other lines.

Under its contract, Invensy Dimetronic will modify the existing ASFA system within the next 18 months.

Based in Madrid and with facilities in Barcelona, Valencia, Lisbon and Porto, Invensys Dimetronic is the leading supplier of signalling and control systems for both mainline and mass transit railways in the Iberian peninsula.
