Signalling system failure on the Madrid-Seville line left traffic in the hands of the control centre
The Madrid-Seville high-speed line, Spain's first, opened in 1992, is the only one still using the older LZB signalling system instead of the ERTMS deployed across the rest of the network. When that system failed, traffic switched to lateral signalling block and came under the orders of Adif's control centre in Atocha, which authorised resuming service "as normal" even though the signal was red and the section was occupied by another train. The line has accumulated recurring faults, many caused by cable theft.
In 45 seconds
- The Madrid-Seville line is the only Spanish high-speed line still using LZB; the rest use ERTMS, deployed over more than 3,000 kilometres.
- With LZB down, traffic switches to lateral signalling block and depends on orders from Adif's control centre in Atocha.
- The control centre authorised resuming service "as normal" with the signal red and the section occupied by an Iryo train.
