Madrid Metro will begin testing its new Series 10,000 trains—destined for Line 6—this April at CAF’s railway test centre in Corella (Navarra), located along the Soria–Castejón line.
These first dynamic trials, set to last six months, mark a crucial stage in commissioning the new fleet, which will be the metro’s first to operate without a driver.
To conduct them, Metro de Madrid has put out to tender a €2.5 million contract that covers integration and functionality testing of the CBTC signalling system. Carrying out the trials externally ensures operations can take place in safe conditions, without disrupting passenger service amid ongoing works and operational constraints on Madrid’s network.
The trains, built by CAF in Beasain and Irún, represent an investment of €531.2 million. Their production was awarded in an initial batch of 40 units in 2024, followed by a second batch of eight additional units in August 2025.
They will share specifications with the current Series 8000 stock, but will be cabless and will feature the latest safety, accessibility, and passenger information systems.
The fleet is expected to enter service on Line 6 in early 2027, completing its full automation process. With over 400,000 daily passengers, Line 6 will become the first fully automated route in the Madrid Metro network.
