The contract includes the system design, implementation and certification of the wayside system, which will optimise the interaction between the existing onboard systems and wayside infrastructure.
Siemens will install Westrace MK2 interlockings, modernise the LZB automated train control system, replace signals with LED lights and upgrade the communications and energy installations. The new Patio de Bello Westrace MK2 interlocking will control a total of 111 track circuits, 58 point machines and 72 signals, and will be fitted with a specific local control system.
Installation will take place at night to ensure normal operation of the line throughout the day, and the project will improve line capacity when completed in 2021.
Line 1 is 25.8km long, with 21 stations, and together with Line 2 carries around one million passengers a day.
