THALES has been awarded two contracts by Spanish infrastructure manager Adif AV to update signalling on the Madrid - Seville high-speed line 30 years after the link opened.
Under the first contract, the supplier will equip electronic interlockings on the line with ETCS Level 2 as well as integrate the system with existing LZB train protection system. Delivery time is 52 months, and the work will take place while the line remains in operation. Work also includes renewal of copper networks used to detect fallen objects on the track. The contract is valued at nearly €80m.
The second contract is worth almost €18m and involves replacing 1306 obsolete FTG track circuits with Thales’ TTC track circuit. This model supports installation of 16 units on each frame, freeing up space in technical cabinets, which will be used for installation of the new ETCS equipment.
The TTC circuits were developed by Thales’ team in Spain and have been tested on both standard and 1668mm-gauge lines as well as with 25kV ac, 3kV dc, and 1.5kV dc electrification.
