The 8000 Series was delivered in 2002. Today, they operate on lines 8 and 12, and occasionally appear on lines 6, 9, and 10 as well. These trains were the first Madrid Metro cars to have regenerative braking. They also feature lights to alert passengers that the doors are about to close, a fire detection and suppression system, backup emergency lighting, lateral evacuation ramps, digital radio communications, aluminum bodies, an aerodynamic design, full front cab window, computerized information displays, and closed circuit television, etc. Some of the trains on Line 8 have a special compartment for transporting luggage from the Nuevos Ministerios station to the airport.
