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 After they were withdrawn from service in Gothenburg, 36 members of the class were sold for use on the Oslo Tramway in Norway, where they ran from 1991 until 2002.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.[1]

The M25 was one of three similar classes, along with the M28 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]
