The Colmenar Viejo City Council has formally requested that Cercanías Madrid management take immediate action to address service deficiencies on the C-4 line.

Local authorities have expressed their concern over the frequency of delays, cancellations, and incidents affecting daily commuters. The letter highlights the specific issue of trains bound for Colmenar Viejo that unexpectedly terminate their route at Tres Cantos station, leaving passengers unable to complete their journey.
The council emphasizes that this situation is particularly critical due to the expansion works on the M-607 road, which involve a 40 million euro investment by the Comunidad de Madrid. Given the temporary mobility disruptions caused by these works, the rail service should serve as a reliable alternative for citizens.

"We cannot ask citizens to use public transport when they leave home every morning without knowing when they will reach their destination."

The formal request includes a demand to ensure strict adherence to schedules, especially during peak hours, and improvements to user information systems during incidents. Furthermore, the Ministry of Transport and Sustainable Mobility has been urged to allocate the necessary resources and investments to ensure the reliability of rail transport in the region.
