The M28 was a class of 70 four-axle trams built for use on the Gothenburg Tramway in Sweden between 1965 and 1967. The class carries fleet numbers 701-770, and was withdrawn from service in 2021. [1]
The M28 was one of three similar classes, along with the M25 and M29 classes. All three classes were of similar exterior design, and any combination of them could be operated together in multiple unit with any vehicle leading. [2]
The M28 Class was built by ASEA and ASJ as 70 single-car trams from 1969 to 1972. The standard gauge trams are 15.132 metres (49 ft 7.7 in) long, 2.650 metres (8 ft 8.3 in) wide and weigh 16.800 tonnes (16.5 long tons; 18.5 short tons). They are equipped with two bogies, each with two axles, giving a Bo'Bo' wheel arrangement. The axle distance is 1.800 metres (5 ft 10.9 in), the bogie-centre distance is 7.000 metres (22 ft 11.6 in) and the wheel diameter is 680 millimetres (2 ft 3 in). [1]
Each tram has four motors totalling 176 kilowatts (236 hp) in power output, giving a maximum speed of 60 kilometres per hour (37 mph). The trams seat 38 people and stand 78 more. The cars are all single-ended (with a single driving cab) and single-sided (with passenger doors only on one side). All cars were built for operation in right-hand traffic, with doors on the right facing the drivers cab. [1] [2]
Between 1958 and 1962, Göteborgs Spårvägar put into service 125 trams of class M25, which were built for left-hand traffic, but less than a year later Sweden decided to change from left to right-side driving. Faced with the need to re-equip with trams suitable for right-hand traffic, the tram company ordered an additional 70 trams in the M28 series, and subsequently the 60 M29 trams. Both series were built for operation in right-hand traffic. [2]
The M28s were delivered before Dagen H (3 September 1967; the date the change was made) and were first placed into service coupled back-to-back to an M25 car, thus creating a double-ended but single-sided coupled-pair. Before the change these car-pairs were driven with the M25 leading, after the change the M28 led. In later years they typically operated in coupled pairs with a leading M29 and a trailing M28, or as single cars on less busy routes, but other combinations were sometimes seen. [2]
After their introduction, the M28s were rebuilt and modernized several times. The most obvious change was the introduction of skirts over the bogies, which that were added to reduce noise and potential for accidents. The wagons were also the subject of a few different alternative colour schemes, both inside and out, and the exterior lights and displays were replaced. In 2010, an interior information display was added, showing the line number, destination and next stop and complementing the automatic stop announcement.[ citation needed ]
It was intended that the M28 and M29 classes would both be replaced by the M32, a variant of the AnsaldoBreda Sirio delivered between 2005 and 2013, but problems with those trams led to both classes being retained. Subsequently the plan was to replace the M28 trams with the M33, a variant of the Alstom Flexity Classic, but before the completion of the delivery of that class, it was decided to take the M28s out of service for safety reasons. The last M28 ran in service on 28 October 2021, with the sudden withdrawal having an impact on tram availability. [3]
Three members of the M28 class still exist in preservation:

Transport in Sweden is available for all four main modes of transport—air, bus, ferry and rail—assisting residents and visitors without their own vehicle to travel around much of Sweden's 450,295 square kilometres (173,860 sq mi).
The Stockholm Metro is a rapid transit system in Stockholm, Sweden. The first line opened in 1950 as the first metro line in the Nordic countries, and today the system has 100 stations in use, of which 47 are underground and 53 above ground. There are three coloured lines, as shown on the tube maps, which form seven numbered routes with different termini. Routes numbered 17, 18 and 19, 13 and 14 and 10 and 11 all go through the centre of the city, resulting in a very centralized system. All three lines and seven routes interchange at T-Centralen station. Apart from this, there are three other interchange between lines, at Fridhemsplan, Slussen and Gamla stan stations.
The Socimi Eurotram (later sold as the Bombardier Flexity Outlook (E)) was an electric tramcar designed for the tram system of Compagnie de Transports Strasbourgeois (CTS). Initially produced by Socimi, after the company became bankrupt Eurotrams were manufactured first by ABB Group's transportation division, then by Adtranz and finally by Bombardier Transportation, who marketed the tram as part of their Flexity Outlook range.
The Hitachi Sirio is a low-floor tram built by Hitachi Rail Italy, a Japanese-Italian manufacturer of trains, trams and light-rail vehicles. It can be ordered as either one-directional or bi-directional and with a variety of track gauges.
The Gothenburg tramway network is part of the public transport system organised by Göteborgs Spårvägar, controlled by Västtrafik in the Swedish city of Gothenburg. The system's approximately 160 kilometres (99 mi) of single track — making it the largest tram network in Northern Europe — is used by around 200 trams as of 2006, which serve twelve day-time and five night-time lines with a combined line length of 190 km. These figures are expected to increase when the second stage of Kringen is finished. The trams perform about 2,000 trips and cover 30,000 km per day. In 2018, 131 million journeys were made.
The ADtranz low floor tram was introduced in the 1990s as the world's first tram with a completely low floor design. This tram was developed by MAN for the Bremen urban transport system. The prototype, tram number 3801, was first publicly introduced on 9 February 1990. From 1991 to 1993, it was being tested in many European cities. Ten German cities have purchased this type. Adtranz took over the rail division of MAN in 1990.
Germany has an extensive number of tramway networks. Some of these networks have been upgraded to light rail standards, called Stadtbahn in German. Straßenbahn and Stadtbahn schemes are usually operated on the legal foundation of the BOStrab, the Tramways Act of Germany.
The Z-class are single-unit bogie trams that operate on the Melbourne tram network. Between 1975 and 1983, 230 trams spanning three sub-classes were built by Comeng, Dandenong. The design was based on two similar Gothenburg tram models, and a prototype built by the Melbourne & Metropolitan Tramways Board. While the Z1 and Z2-class trams were very similar, the Z3-class had significant design changes.
KTM-1 is a Soviet-made two-axle tram with a metal body. KTP-1 is a two-axle trailer car to intended to work under KTM-1 traction. It was the first Soviet-made tram to be originally single ended, as well as designated to work on looped lines. It was the first Soviet-made tram with wide four-segment folding doors and bigger passenger storage spaces. Doors were driven pneumatically.
The Vinnytsia Tramway network is the part of the public transportation system that since 1913 serves Vinnytsia, the administrative center of the Vinnytsia Oblast, Ukraine. The tram system has a narrow rail gauge of 1,000 mm that only exists in Ukraine in the cities of Lviv, Zhytomyr and Yevpatoria, as well as Vinnytsia. The system currently consists of 21.2 km of tracks.
SL79 is a class of 40 articulated trams operated by the Oslo Tramway of Norway. The trams were a variation of the Duewag trams that had been developed by the German manufacturer since the 1950s. The six-axle vehicles are unidirectional with four doors on the right side. The trams can seat 77 passengers three and four abreast, with an additional 91 people able to stand. Power output is 434 kilowatts (582 hp), provided by two motors on the two end bogies, that supplement a central unpowered Jacobs bogie located under the articulation. The trams are 23.0 metres (75.5 ft) long and 2.5 metres wide. They are capable of 80 kilometres per hour (50 mph) and have standard gauge.
SL95 is a series of 32 low-floor, articulated trams operated on the Oslo Tramway. The series was built by Italian rail manufacturer Ansaldo/Firema, later known as AnsaldoBreda, and delivered between 1999 and 2004. Capacity for the eight-axle, three-section vehicles is 212 passengers, of which 88 can be seated. The name derives from being ordered in 1995. Original plans called for the delivery to be between 1997 and 1998. Delivery took many years due to a magnitude of technical flaws, including high noise levels, freezing during the winter and corrosion. The trams are 33.12 metres long, 2.6 metres wide and 3.62 metres tall. The aluminum vehicles weigh 64.98 tonnes and have a power output of 840 kilowatts (1,130 hp).
Class B and Class E, normally referred to as Gullfisk, were a class of 46 trams built by Strømmens Værksted and Skabo Jernbanevognfabrikk for Oslo Sporveier and Bærumsbanen of Oslo, Norway, in 1937 and 1939. They were the first aluminium trams to operate on the Oslo Tramway and the first bogie trams to operate on street lines. They had contemporary modern electronic equipment, a streamlined shape, and comfortable accommodation. Until 1964, they were also faster than any other Norwegian tramcar or suburban railcar.
The M25 was a class of 125 four-axle trams built for use on the Gothenburg Tramway in Sweden between 1958 and 1962. The class was used in passenger service in Gothenburg until 1994, undergoing major rebuild to accommodate Sweden's switch from driving on the left-hand side of the road to the right in 1967. After they were withdrawn from service in Gothenburg, 36 members of the class were sold for use on the Oslo Tramway in Norway, where they ran from 1991 until 2002. In Oslo the trams were known as class SM91, and were numbered 264 to 299.
SM53, originally designed MBO and colloquially known as Høka, were a class of 58 trams and 50 trailers built by Høka and Hägglund for Oslo Sporveier. The units were used on the Norway's Oslo Tramway from 1952 until 2000. The 14.7-meter long and 2.5-meter wide trams weighed 16.9 tonnes. They had four motors providing a combined power output of 180 kilowatts (240 hp), allowing for a top speed of 60 kilometers per hour (37 mph).
The Bombardier CR4000 is a 76% low floor model of the Bombardier Flexity Swift series of tram operated by Tramlink in London. They are based on and very similar in appearance to the K4000 built for use on the low-platform routes of the Cologne Stadtbahn network. Built between 1998 and 2000, the trams entered service in the spring of 2000.
The Rhaetian Railway Be 4/4 is a class of 11 kV 16.7 Hz AC metre gauge railcars operating under the traffic numbers 511–516 on the so-called core network of the Rhaetian Railway (RhB), which is the main railway network in the Canton of Graubünden, Switzerland.
The Malmö tramway network was a tram network that existed as a public transit system in Malmö, Sweden in some extent from 1887 until 1973. In 1987 a new route of about 2 km (1.2 mi) was built as a historic line, which remains in operation today.
Trams have been used since the 19th century, and since then, there have been various uses and designs for trams around the world. This article covers the many design types, most notably the articulated, double-decker, drop-centre, low-floor, single ended, double-ended, rubber -tired, and tram-train; and the various uses of trams, both historical and current, most notably cargo trams, a dog car, hearse tram, maintenance trams, a mobile library service, a nursery tram, a restaurant tram, a tourist tram, and as mobile offices.
The M29 is a class of 60 four-axle trams built for use on the Gothenburg Tramway in Sweden between 1969 and 1972. The class is still in passenger service in its home city and carries fleet numbers 801–860, although some members have been withdrawn.
