A shortlist of three prequalified bidders will be announced in June and Gothenburg Tramways plans to conclude the contract by the end of May 2015. The first units from the initial batch will enter service in Spring 2017 and the vehicles will be delivered at a rate of two per month, with the last due to arrive in the city in 2019.

The unidirectional trams will be classified M33 and the first batch will be supplied as 29m and 33m-long units. The contract includes options for longer vehicles (40-45m) and an option to add additional sections to the initial batch.

Gothenburg Tramways says that it will need 100 new LRVs by 2024. The company currently operates a fleet of 263 trams, the newest being the 65 M32 Sirio vehicles supplied by AnsaldoBreda from 2004 onwards.

Gothenburg's 82km standard-gauge tram network comprises 13 lines and carries around 108 million passengers per year.
