A contract has been formalised to optimise the capacity of the C-3 line between San Cristóbal and Aranjuez. The study, with a budget of €363,000, will last 24 months.
The Ministry of Transport and Sustainable Mobility has taken a significant step towards improving rail transport in Madrid by formalising the contract to develop a feasibility study aimed at optimising functionality and increasing the capacity of the C-3 Cercanías line. This stretch, which connects San Cristóbal Industrial with Aranjuez, has been a concern due to its high level of congestion during peak hours and the coexistence of different types of traffic: Cercanías, medium distance, and freight.
The study has an initial timeframe set at 24 months and has a total budget of €363,000, including VAT. The drafting of the study was awarded last May and is expected to analyse various actions that will improve both the capacity and reliability of the rail service.
The C-3 line includes nine stations or stops: San Cristóbal Industrial, El Casar, Getafe Industrial, La Tenería (under construction), Pinto, Valdemoro, Ciempozuelos, Seseña (out of service), and Aranjuez. In this context, the Ministry has indicated that the planned improvements could include optimisations in the current systems as well as the possible implementation of a third or fourth track in part or all of the stretch.
As this project progresses, it is important to remember that the development of the rail system aims not only to alleviate current traffic but also to contribute to more sustainable mobility in Madrid. According to statements from the Ministry itself, these actions are aligned with the objectives set by the 2030 Strategy, which aims to enhance sustainable metropolitan mobility through efficient rail services.
Furthermore, the improvements are expected to positively impact travel times for other regional services connected to this line. This is crucial considering that public transport is an increasingly necessary alternative in light of rising road traffic and associated environmental concerns.
This is not the first time such initiatives have been addressed; back in 2022, the Ministry approved an indicative strategy for the development and infrastructural maintenance of the Spanish rail system. This strategy establishes basic guidelines aimed at meeting future needs both operationally and financially for the sector.
As these improvements are implemented on the C-3 line, users can expect a more reliable and efficient service. For those interested in using this line during its regular operation or while the study is ongoing, it is recommended to stay updated on schedules and possible operational changes over the next two years.
