The CAF Inneo M7 is a series of electric multiple unit (EMU) trainsets used in the Amsterdam Metro. This train was put into service on 28 February 2023, and is expected to remain in operation for at least 30 years.
With a length of three carriages (together almost 60 meters), an M7 set is half as long as an M5 set. The intention is to run double sets during peak hours and single sets outside peak hours, preventing overcapacity and allowing better planning of maintenance. [3]
The M7 rolling stock initially serves the East Line (Oostlijn) and the Ring Line (Line 50). Deployment on the North/South Line (Line 52) is not planned at this time. CAF also supplied the 37 M4/S3 trainsets for the Ring Line in 1996-1997 and won the tender in 2016 for manufacturing 15G series for Amsterdam Tram.
The following reasons make the acquisition of new trainsets for Amsterdam necessary in the short term:
In addition, in 2012, at the urging of the then Alderman for Traffic, Transport, and Infrastructure, the desire arose to have a mixed fleet of long (116 meters, 6 carriages, M5/M6 series) and semi-long (a maximum of 61 meters, 3 carriages) rolling stock. The capacity of two coupled M7 sets operating in multiple-unit configuration is equal to that of a single M5/M6 set. As a result, further acquisition of additional M5/M6 series sets was abandoned after five of the 12 optioned sets were delivered. During the first year after commissioning in 2023, only single M7 sets were operated; from 2024, coupled sets are also in service.
In August 2016, the Amsterdam Regional Transport Authority (Stadsregio Amsterdam) and GVB created a "Program of Requirements" outlining the specifications for the new metro trains.
Initially, the plan was for a vehicle up to 61 meters long and 3 meters wide, with a capacity of around 450 passengers (including at least 75 seats) and capable of being coupled with other trains. The design and layout had to align with the appearance of the M5/M6 series. The exterior design of the M5/M6 references the first metro trains used in Amsterdam. Based on these specifications, it was estimated that 25 to 30 train sets would be needed. The final number, 30 units, was confirmed in December 2016, and the procurement process began in January 2017. The first train set (No. 163) was delivered on 23 August 2021, and the last one from the initial batch (No. 192) was delivered on 28 November 2024.
In September 2016, the Executive Board of Stadsregio Amsterdam decided to conduct additional research into purchasing longer 80-meter trains. After analysis by GVB and the transport authority, it was found that in certain scenarios, 80-meter trains would be more efficient than 60-meter ones. [4] However, if they had chosen the longer trains after completing the study, it would have delayed the project. Therefore, the procurement continued with the 60-meter trains as the baseline.
On April 30, 2018, GVB announced that the Spanish railway manufacturer CAF had been selected as the supplier, following a tender process that began in 2017. [5] The order for 30 trainsets amounted to 225 million euros, with an option to purchase up to 30 additional units.
On July 11, 2024, GVB announced that it would partially exercise the option for additional trains and would order between 11 and 13 extra units. The exact number depends on the outcome of investigations into two damaged M5 trains. If they are repaired, 11 M7 trains will be ordered; if they are replaced, 13 will be purchased instead. [3]
The M7 must be equipped for automatic train operation.
In addition, the M7 must be compatible with platform screen doors. However, if platform screen doors are installed, these trains will no longer be able to run in coupled configurations on routes shared with M5/M6 trains. This is because the offset at the coupling point would cause the doors of a coupled train to misalign with the position of the platform doors. Therefore, the procurement also took into account the possibility of future extensions, allowing these trains to be lengthened with additional carriages to a maximum length of 123 meters.
In March 2018, it was discovered that incorrectly placed buffer stops at Amsterdam Centraal Station as the terminus for the East Line made it impossible for two coupled M7 trains to stop there. Additionally, using coupled M7 trains on Line 52 is currently not feasible due to the tight positioning of fire safety screens at Europaplein Station, which would descend in case of fire. [6] The Metro and Tram Service is investigating what adjustments are necessary and the associated costs.
The Bucharest Metro is an underground rapid transit system that serves Bucharest, the capital of Romania. It first opened for service on 16 November 1979. The network is run by Metrorex. One of two parts of the larger Bucharest public transport network, Metrorex had an annual ridership of 142,783,000 passengers during 2023, compared to over a billion annual passengers on Bucharest's STB transit system. In total, the Metrorex system is 80.1 kilometres (49.8 mi) long and has 64 stations.
GVB is the municipal public transport operator for Amsterdam, the capital of the Netherlands, operating metro, tram, bus and ferry services in the metropolitan area of Amsterdam.
The Brussels Metro is a rapid transit system serving a large part of the Brussels-Capital Region of Belgium. It consists of four conventional metro lines and three premetro lines. The metro-grade lines are M1, M2, M5, and M6 with some shared sections, covering a total of 39.9 kilometres (24.8 mi), with 59 metro-only stations. The premetro network consists of three tram lines that partly travel over underground sections that were intended to be eventually converted into metro lines. Underground stations in the premetro network use the same design as metro stations. A few short underground tramway sections exist, so there is a total of 52.0 kilometres (32.3 mi) of underground metro and tram network. There are a total of 69 metro and premetro stations as of 2011.
The Amsterdam Metro is a rapid transit system serving Amsterdam, Netherlands, and extending to the surrounding municipalities of Diemen and Ouder-Amstel. Until 2019, it also served the municipality of Amstelveen, but this route was closed and converted into a tram line. The network is owned by the City of Amsterdam and operated by municipal public transport company Gemeente Vervoerbedrijf (GVB), which also operates trams, free ferries and local buses.
The Alstom Metropolis is a family of electric multiple units designed and produced by the French rolling stock manufacturer Alstom. It is designed for high capacity rapid transit or metro rail infrastructure systems. Trains can be run in various configurations, the length alone varying between two and ten cars; it is also suitable for both manned or unmanned operations.

It dates back to 1875 and since 1943 has been operated by municipal public transport operator Gemeentelijk Vervoerbedrijf (GVB), which also runs the Amsterdam Metro and the city bus and ferry services. Amsterdam has the largest tram network in the Netherlands and one of the largest in Europe.
Amsterdam Amstel is a railway station in Amsterdam, Netherlands. The station opened in 1939. It is located to the southeast of Amsterdam Centraal in the borough of Amsterdam-Oost, near the Amstel river. Amsterdam Amstel is used daily by 50,000 train and metro passengers. Rail services at the station are provided by NS, the principal railway operator in the Netherlands. Metro, tram and city bus services are provided by municipal operator GVB. Regional buses are operated by Transdev and Keolis.
The main public transport in the Netherlands for longer distances is by train. Long-distance buses are limited to a few missing railway connections. Regional and local public transport is by bus and in some cities by metro and tram. There are also ferries.
Amsterdam tram line 25, also known as the Amsteltram, is a tram line running south from Amsterdam Zuid station in Amsterdam via Westwijk in Amstelveen to Uithoorn Centrum in Uithoorn. It officially opened to Westwijk on 13 December 2020. The tram line replaced metro line 51, a light rail line (sneltram) that ceased running south of Amsterdam Zuid station on 3 March 2019 to convert it for low-floor trams. Tram line 5 shares the stops with line 25 between Zuid station and Oranjebaan stations. Line 5 had also shared the same tracks with metro line 51, the former using low-level platforms for regular trams, and the latter using high-level platforms.
The Intercity Nieuwe Generatie, or ICNG, nicknamed "Wesp" (Wasp) is an electric multiple unit trainset of the Dutch Railways. In addition to supplementing the existing intercity rolling stock, it will replace the Bombardier TRAXX locomotives and Intercityrijtuig coaches on the high-speed line between Amsterdam and Belgium. This will provide the connection that was originally planned to be provided by the Fyra service, which was cancelled in 2013.
Metro Line 51, also known as the Ring Line, is an Amsterdam Metro line running from Amsterdam Centraal station to Isolatorweg metro station, almost creating a full circle through Amsterdam. It was opened in December 1990 as a metro/tram hybrid line named sneltram and served the suburb of Amstelveen. Using special rolling stock, the Amstelveen Line ran as a metro on 750 V DC third rail from Amsterdam Centraal to the Amsterdam Zuid station, where it would switch operation modes and utilize 600 V DC overhead lines and end at Poortwachter. An extension to Westwijk was completed in 2004. In Amstelveen, the line partially ran on the same track as tram line 5 and had many level crossings.
Metro Line 52, also known as the North–South Line (Noord/Zuidlijn), is part of the Amsterdam Metro network. The line starts in Amsterdam-Noord, continues under Amsterdam-Centrum to its terminus in Amsterdam Zuid station. It has six intermediate stops: Noorderpark, Centraal Station, Rokin, Vijzelgracht, De Pijp, and Europaplein. The line was officially opened on 21 July 2018 by the mayor of Amsterdam, Femke Halsema and was opened to the public on the next day, 22 July 2018.
Metro Line 53, also known as the Gaasperplas Line (Gaasperplaslijn), is a line of the Amsterdam Metro running between Amsterdam Centraal and Gaasperplas metro station in Amsterdam-Zuidoost. It is the eastern branch of the Oostlijn.
Metro Line 54, also known as Gein Line is a line of the Amsterdam Metro between Amsterdam Centraal station and Gein station in the Gein district in Amsterdam-Zuidoost. This is the southern branch of the Oostlijn.
The Alstom Metropolis BM4 is a family of metros designed for the Bucharest Metro, with 13 six-car trainsets currently built by Alstom at the Taubaté, Brazil plant as of 2023.
S1 and S2 units, collectively called S1/S2, were electric multiple unit trains used on the Amsterdam Metro in Amsterdam, The Netherlands. Built by La Brugeoise et Nivelles (BN), 13 of these units were ordered by the GVB in 1988 (S1), as well as an additional 12 later in 1991 (S2), for a new line from Amsterdam Centraal station to the suburb of Amstelveen. This line, named the Amstelveen Line and later numbered as 51, was initially expected to be a full metro line, but it was later changed to a tram-metro hybrid named sneltram due to protests against the metro in the preceding decades. From Amsterdam Centraal to Amsterdam Zuid, Line 51 ran as a regular metro on 750 V DC with third rail pick up, used on the regular metro network. At Zuid, the trains converted to 600 V DC via overhead lines, used by the city's tram network, and served Amstelveen as a faster tram service. On the latter part of the route, the line shared tracks and stops with a regular tram line and ran on public roads with crossings.
Metro Line 50 is a line of the Amsterdam Metro between the Isolatorweg and the Gein district in Amsterdam-Zuidoost. Although the line is a tangential line, it is also known as the Ring Line (Ringlijn), because the embankment of the Ringspoorbaan is used between Sloterdijk station and the Rozenoordspoorbrug.
The Alstom Metropolis M5 is a fleet of 28 six-car electric multiple unit (EMU) trains for the Amsterdam Metro, delivered by the French manufacturer Alstom between 2012 and 2015. The trains are based on the Alstom Metropolis series, with variants in use by metro systems in various foreign cities such as Barcelona, Budapest, Santiago, and Shanghai. Although the trains are suitable for driverless operation, they are currently operated by drivers.
