Metro de Madrid

There are 246 carriages in the series. 9000

The body of the series 9000 units is made of aluminium, including the chassis, and they have four doors on each side for passenger access/exit. These carriages have an interconnecting passageway, for a composition of three or six carriages, depending on the sub-series, which are fully interconnected inside.

The series 9000 units all have air-conditioning and heating and auxiliary systems control equipment, equipment to record safety parameters during operation, and a passenger information system. They also have a video-surveillance system, systems for fire detection and extinction using water mist, as well as a public address system and TETRA digital radiotelephony. Likewise they are equipped with train protection systems (ATP and ATO). One of the most interesting new features of the series 9000 carriages (as in the series 3000) is that they have been adapted to provide total accessibility, with the following systems:

-Folding ramps to provide access to wheelchairs on the doors, on both sides, closest to the drivers cabin.
-Automatic opening, in all cases, of the doors with ramps, which unfold automatically.
-Space reserved for wheelchairs, signposted and equipped with safety belt.
-Automatic opening, in all cases, of the other doors of the first carriage, to facilitate access to persons with sight problems.
-Optical and acoustic signals indicating that the doors are open, to permit easier location by persons with sight problems.
-All doors have contrasting colours to the colours around them
-Interior colour contrasts (doors, seats, etc.).
