Serie 8000

Series 8000 (2nd batch). 2010-2014

The 8000 series is a type of wide gauge train of the Madrid metro built by CAF (Spain) and Alstom (France) during the years 2000-2003 and by CAF between 2008 and 2011 that provides service on lines 6, 8, 9, 10, 11 and 12.

The trains of this series are divided into two groups: single voltage 1500Vdc, from the M-8001, and dual voltage 600/1500Vdc from the M-8403; which is why the latter are known as 8400.

*Not to confuse with 8000 series from TMB.

Series 8000 (1st batch). 2000-2003


On February 29, 2000, Metro de Madrid signed a contract with the manufacturers CAF and Alstom for the supply of 47 units of 3 cars, expandable to 6, intended to provide service on lines 8 and 12 (37 trains) and reinforcement for other lines (10 trains). In December 2001, the first 10 trains on the airport line entered service.

Due to the delay in the delivery of the first 7000 series trains, since line 10 was reopened under 1500Vcc in 2002, they also provided service on it in double composition trains.

On April 11, 2003, the Metrosur entered service, with its fleet of 27 trains practically complete.

Within the framework of the expansion and improvement plan of the Madrid metro developed between 2007 and 2011, the Community of Madrid awarded CAF the manufacture of 43 new 8000 trains. 30 of them would be dual-voltage 6-car units for the Circular line, 7 single-voltage units of 4 cars to distribute between lines 8 and 10, and eight of 3 cars for line 12.

In May 2010, trains 8400 from the first batch on line 6 could be seen in tests with passengers, although it was not until December 20 of the same year when the first newly manufactured trains entered service, both on the Circular and on the line 11.


All 8000 series cars have wide clearance, have 4 doors per side, have air conditioning, television screens, LED teleindicators, fire extinguishing system using water mist, intercom for communication with the driver and protection systems and ATP and ATO conduction. As in the 7000 series, the cars are interconnected by means of bellows, which facilitates transit inside the train.

Car types

The compositions of this series can be formed using three different types of car: the M (engine with a cabin with 22 seats and capacity for 171 people standing), S (intermediate engine with 28 seats and capacity for 193 people standing) and R (intermediate trailer with the same capacity as the S car).

Numbering of compositions

All trains are designed to run with 6 cars. However, only the 30 of line 6 have their complete composition. With a view to the future, the extreme cars always have the numbering that would correspond to them if it were a train of 6 cars and the intermediate cars have the maximum possible numbering. For example, the first composition of the series consists of cars M-8001+S-8004+R-8005+M-8006. As you can see, the R-8002 and S-8003 cars are missing, which will be manufactured when the composition is completed.

For this reason it is also the case that the first car of the 8100 subseries is the M-8103 instead of the M-8101, since otherwise the immediately preceding train could not have 6 cars.

Interior of 8400 (1st batch)


In the trains of the first batch (14 8000, 27 8100 and 10 8400) the light green color predominates in the doors and bars, while the plastic coverings are a bluish green color. For its part, the floor has a blue tone. In the extreme cars there is a place reserved for wheelchairs.

For their part, the trains of the second batch (30 8400 and 15 8000) have creamy white linings, yellow bars and red floors. In the case of those on line 6, in addition to the space for wheelchairs, they also have a space for transporting bicycles in the extreme cars.


When acquired in 2000, the 8000 series trains were subdivided into 3 different subseries:


There were 10 compositions (made up of cars from M-8001 to M-8060) destined for line 8 whose difference with those of line 12 was that they had trunks for transporting luggage. Furthermore, with the inauguration of the baggage check-in service in Nuevos Ministerios, an isolated compartment was enabled in the odd-numbered motor cars for the transport of containers, although later, due to their low use, they were removed.

In 2006 these 10 trains were expanded into a car, type S.

With the arrival of the single-voltage trains of the second batch, this subnumbering continued to grow, since the first car is the M-8061, which circulates on line 11.


Starting with M-8103, the 27 3-car trains destined for line 12 began to be numbered, whose characteristics were similar to the previous ones, but it was decided to number them separately. That is why it is the case that the M-8066 car is 8 years more modern than the M-8121.

Between 2006 and 2007, with the second batch, the first four compositions of this subnumbering received a fourth car, type S​ and became part of the fleet of line 8.


The two-voltage trains of the 8000 series begin their numbering from car M-8403. Originally there were only 10 of this type, intended to reinforce all wide gauge lines. The one that has been used the most at 600Vcc is the 9. Under 1500Vcc they are equipped with a different drive chain than the rest of the series, which is why they sound different. This drive chain was the same one used in the 3000 series, which is why the sound is similar.

The new trains on line 6, as they belong to the 8000 series and are dual-voltage, are subnumbered 8400. For this reason, the first car in this second batch of trains is the M-8463.

For propaganda reasons, the Community of Madrid has sold these trains as a new series different from those of 2003; However, as can be seen just by the numbering and common characteristics, it is not something real.
