Operators

Milan

Azienda Trasporti Milanesi (ATM), the city transport company of Milan, has bought 93 Sirios (all one direction cars). In 2002, the first carriages were delivered. The ATM has 58 seven section Sirios (7100 series) with a length of 35.35 metres (116 ft 0 in); these trams have a capacity of 285 people, of which 71 can sit. The ATM has also 35 five section Sirietto (literally "little Sirio": 7500 series) with a length of 25.15 metres (82 ft 6 in); these trams have a capacity of 191 people, of which 50 can sit. Both types of Sirios have a width of 2.40 metres (7 ft 10 in) and have been built for the unusual track gauge of 1,445 mm (4 ft 8 7⁄8 in). The maximum speed is 70 km/h (43 mph). Part of the 7500 will be numbered in the 7600 series because of minor modifications. It is not exactly known how many Sirio will be built.

All Sirios in Milan sport a dark green livery; the Siriettos sport either the dark green livery or a white-and-yellow livery.

Gothenburg

New M32 tram out for a test run in August 2006

The city of Gothenburg, Sweden, ordered 40 one-directional Sirio trams which were to be put into service on the Gothenburg tram network during 2005 and onwards. The trams were delivered late and functioned poorly when put into traffic. Among reported problems were excessive track damage caused by the trams, malfunctioning air conditioners inside the trams and poor ride quality. The City of Gothenburg therefore withheld a large part of the payment for a delivered tram until fully operational.[1] On December 3, 2009, the city authorities exercised their option for a further 25 trams of the same design at a cost of €61 million.[2] In February 2013, 38 out of the total 40 trams delivered in the first series were taken out of service due to extensive corrosion on the chassis.[3] Repairing the rusted chassis and moldy passenger floors is expected to be completed by 2017,[4] at a cost for Gothenburg council of an extra €10 million according to the revised contract, although Ansaldobreda bears the majority of the cost for these deficiencies. Of the 65 trams purchased, only about 35–40 are usable.[5] Due to further delays on the part of Ansaldobreda with the corrosion repairs and substandard quality in completed works, the council of Gothenburg cancelled the contract for corrosion repairs in November 2015.[5] None of the three repaired trams that Ansaldobreda delivered was in working order and might be scrapped. The investigation launched into the matter found that the trams were jerry-built and that Ansaldobreda did not have the will or the competence to do anything about the problems.[6] It was also discovered that the badly built trams have resulted in extensive track damage that will be very costly to repair, adding to the "fiasco" of the Gothenburg Ansaldobreda tram affair.[7]
