We are modernising line 4 of the underground and works are now more than 50% complete
The comprehensive reform of line 4 of the underground, with a budget of 47 million euros, seeks to enhance the security and reliability of the running of trains and improve service quality. To achieve that, the railway signalling and the electrification of the overhead lines will be standardised, installing a complete system of rigid catenary. This will allow the number of network incidents to be reduced and the reduction in maintenance costs.
The new signalling will provide the line with greater security and availability. It will also increase transport capacity, since it will allow a higher number of trains to operate at the same time.
“The enlargement projects that Metro de Madrid is working on at this time do not mean we should forget the necessary modernisation of the oldest lines and stations, both in terms of accessibility and in improved designs and technology for access and the running of trains. This is the only way to guarantee safe, sustainable, fast and competitive travel for the people of Madrid”, remarked Ángel Garrido.
The regional councillor apologised for any inconvenience that the closure may cause over these weeks for users of line 4. However, he underlined that they will be rewarded with faster trains and shorter waiting times between trains when the line re-opens.
In parallel to these works, Metro de Madrid is modernising four stations on the line: Esperanza, Prosperidad, Arturo Soria and Alfonso XIII, although these works are independent. The aim is to replace the cladding, obsolete installations and technology on the platforms and access ways by other more modern materials and equipment adapted to current regulations.
In addition, the drainage and sanitation system will be extended at stations with a new waterproofing system, new electricity conduits will be installed and new furniture fitted. In addition to these works on stations, the ceiling at Avenida de América station will also be waterproofed. The works on line 4 also provide for the removal of asbestos from installations in tunnels and stations.
Works underway 24 hours a day
The works are underway 24 hours a day, seven days a week, with a team of up to 400 people and 20 auxiliary vehicles. Once the service re-opens to passengers in mid-March, actions will continue at night-time to definitively consolidate the new signalling and catenary system. These works will continue for a further three to five months.
The Regional Government of Madrid guarantees the public transport service during the improvement works on line 4 of the underground, which began on 13 January. To cover this, the Regional Transport Consortium has established additional services to guarantee passenger mobility, which includes a special bus service, at no additional costs to users, as well as increased services on certain underground and Municipal Transport Enterprise of Madrid (EMT) bus lines. This will remain active until the modernisation works are terminated.
A special bus service, provided by the EMT will cover the stretch between Avenida de América and Pinar de Chamartín, with 35 vehicles which will run every 3-5 minutes between 06:00 and 01:30.
The stretch between Avenida de América and Argüelles already has a broad offer of alternative public transport during the closure of line 4, but will also enjoy increased services. Specifically, more trains will run on lines 1, 2, 6 and 8 of the underground and on EMT bus lines 9, 21, 29 and 70, 72, 73 and 120.
