MX3000 is an electric train used on Oslo Metro in Oslo, Norway. The multiple units are produced by Siemens, who started serial delivery in 2007. Seventy-eight three-car units have been ordered by Kollektivtransportproduksjon, and five by Akershus County Municipality. They will replace the older T1000 and T1300 stock that has been used on the Oslo Metro since 1966. Delivery is assumed to be completed in 2010, by when all the T1000 and T1300 trains will have been retired. The trains are built as units of three cars, though they are sometimes operated as double units. The units are 54.14 meters (177.6 ft) long, and weigh 98 tonnes (96 long tons; 108 short tons) empty. They have a power output of 1,680 kilowatts (2,250 hp), allowing speeds of 70 km/h (43 mph). Seated capacity is 138 seats, and total capacity is 493 riders. The MX3000 is not equipped with pantographs, so they cannot be used on the Holmenkoll Line until it is upgraded to metro standard in 2011. New features for the Oslo Metro introduced with the MX3000 include air suspension, regenerative brakes and batteries for operating at the depot. The first series of 33 units were ordered in 2003, followed by an additional order for 30 in 2005 and a further 20 in 2008. The trains have been financed by Oslo Package 2, and each unit costs about 45 million kr.
