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.

[3] Each tram has four motors totalling 200 kilowatts (270 hp) in power output, giving a maximum speed of 60 kilometres per hour (37 mph).

Less than a year after that final delivery, Sweden took the decision to change from left to right-side driving on Dagen H (3 September 1967).

[2] At the same time, most of the M25s were gradually sent back to Hägglunds to be converted to right-hand driving, with the passenger doors moved from the left to the right when facing the drivers cab.

[2] The reason for retaining the 15 M25v trams was the opening in 1969 of the initial phase of the Angeredsbanan [sv] that had stub terminals but had all its platforms on the eastern side of the track.

The further conversion was required because the Angeredsbanan used 750V electrical supply as opposed to the 600V of the city trams, and also because of the higher speeds and tunnel sections encountered.

The method of operating into stub terminals used on the Angeredsbanan could not be adopted in Oslo as the tram routes had platforms in the conventional near-side position.

After the need for double-ended sets had passed, M25 trams continued to operate as single cars or in pairs coupled with the doors on the same side.

During the class's operation in Oslo, safety concerns were raised after a fatal accident during the evening rush hour at Holbergs plass [no] on 16 January 2001.

[14] In the aftermath of the accident, Oslo Sporvognsdrift stopped coupling the trams together in two-car trains and ran them only individually.

[7] In the Oslo District Court, both the company and the driver were acquitted on the homicide charge, but found guilty on lesser counts.

[16] The conviction against tram driver on the lesser counts regarding failure to demonstrate due care in the traffic were upheld, and she received a 30-day suspended jail sentence.
