OS MX3000

MX3000 is an electric train used on Oslo Metro in Oslo, Norway. The multiple units are produced by Siemens Mobility, who started serial delivery in 2007. Seventy-eight three-car units were ordered by Sporveien, and five by Akershus County Municipality. They replaced the older T1000 and T1300 stock that was used on the Oslo Metro since 1966. By 2010, the last T1000 and T1300 trains had been retired and replaced by 83 three-car units. 32 additional sets were ordered, and the final train set was delivered in 2014, increasing the fleet to 115 units.

The trains are built as 3-car units, though they often operate 2 coupled units in regular service (except for line 1). The units are 54.34 metres (178 ft 3 in) long, and weigh 98 tonnes (96 long tons; 108 short tons) empty. They have twelve 140-kilowatt (190 hp) traction motors, allowing speeds of 70 kilometres per hour (43 mph). Seated capacity is 138 seats, and total capacity is 493 passengers. The first series of 33 units were ordered in 2003, followed by an additional order for 30 in 2005, 15 in 2008, and 32 in December 2010. Financed by Oslo Package 2, each unit cost about 45 million kr.
