The President of the Community, Isabel Díaz Ayuso, has announced the start of the process to declare a collection of fourteen Metro carriages displayed in Chamartín as a Bien de Interés Cultural. The cars range from 1919 to the sixties.
The President of the Community of Madrid, Isabel Díaz Ayuso, announced during the Debate on the State of the Region the intention to declare Bien de Interés Cultural the collection of fourteen historic carriages of the Madrid Metro exhibited at the Chamartín station. The regional government has already initiated the administrative process. According to Madrid Actual, the measure affects a collection that can currently be seen at the capital's station.
Twelve of the fourteen cars are restored and displayed in Chamartín. The other two, the M-18 and the R-18, remain in the depots undergoing restoration. The carriages retain wooden doors, floors of the same material, upholstered seats, and lamps with glass shades.
The collection spans from the first trains put into service in 1919 to materials from the modernization of the sixties. Among the oldest pieces are four cars of the Cuatro Caminos type, built in 1919 for the first line, between Sol and Cuatro Caminos.
The M-6 retains the modifications from the thirties, with a single driving cab, manual doors, and a lantern on the roof to ventilate the interior. The Salamanca cars from 1943, intended for line 4, were the first in the Madrid Metro with four doors.
The most notable aesthetic change came with the series 1000. The M-1121 and M-1122 cars, built in 1965, replaced the traditional red with a green and greenish-grey exterior. These vehicles remained in service until 2002.
