The full reopening of Madrid Metro’s Line 6 has been moved up by a few days and will take place this Saturday, 20 December. This milestone concludes the first phase of the comprehensive refurbishment of the line, which is being prepared for full automation.
During the works — which required suspending services between Moncloa and Legazpi via Avenida de América since 6 September — several key upgrades have been carried out, including:
- Reinforcement of platform edges.
- Renewal of track.
- Replacement of the remaining ballast track with slab track.
- Easing of curves at station approaches to allow higher speeds.
- Conversion of overhead line voltage from 600 V DC to 1,500 V DC, improving acceleration.
These improvements reduce journey times and enhance service reliability. The stations are now also ready for the installation of platform screen doors — essential both for passenger safety and the line’s full automation process.

The supply, installation, and two-year maintenance of these doors will be undertaken by the joint venture Puertas andén Línea 6, formed by Faiveley and two companies from the Comsa Group.
To carry out the installation, Metro will bring forward the weekday closing time of Line 6 to 23:00, from Sundays to Thursdays, starting on 7 January after the Christmas holidays. No further full closures are planned for the network’s busiest line.
In parallel, Alstom is working on upgrading the Cityflo 650 CBTC signalling system to operate in GoA 4 (fully automated mode).
