| Notes | |
SL95 is a series of 32 low-floor, articulated trams operated on the Oslo Tramway. The series is built by Ansaldo/Firema of Italy 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 (108.7 ft) long, 2.6 metres (8 ft 6 in) wide and 3.62 metres (11.9 ft) tall. The aluminum vehicles weigh 64.98 tonnes (63.95 long tons; 71.63 short tons) and have a power output of 840 kilowatts (1,130 hp).
The trams operate all services on lines 13, 17 and 18. Due to their heavy weight and large turning radius they are unsuitable for the other lines. However, they are the only bi-directional trams in the fleet, and are needed on lines 17 and 18 along the Ullevål Hageby Line. The trams cost about 20 million kr each, but discounts were awarded after the delays and technical faults.
In the early 1990s, Oslo Sporveier was in need of new trams to operate on their network. Except for 40 articulated SL79-trams that had been delivered between 1982 and 1990, the company had several series of non-articulated trams with trailers that were built before 1960. The largest series were 13 SM53s, 11 rebuilt SM83s and 28 trailers, in addition to 34 SM91s that had been bought used from the Gothenburg Tramway in 1991. Oslo Sporveier considered several possibilities for new trams, including ordering additional SL79s, purchasing motorized trailers for SL79, purchasing new low-floor trams, purchasing trams from ČKD Tatra, purchasing the 11 used TT Class 8 trams from Trondheim, rebuild the SL79s with an additional section or purchasing used articulated trams from abroad. Purchasing used material and rebuilding the SL79s was quickly rejected. An non-articulated Tatra tram was tested in Oslo during January 1991.
