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. 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.[5] Financed by Oslo Package 2, each unit cost about 45 million kr.

History

In 1966, the Oslo Metro opened as an upgrade of two existing suburban tramways, the

Holmenkoll Lines still used overhead wires, and would not be able to use the new stock. Both systems were at the time being considered for conversion to light rail systems, that would connect to the Lilleaker- and Ullevål Hageby Line, respectively.[8][9]

The old fleet of T1000 and T1300 consisted of 195 cars in eight series.[10][11] The T1000 was the original series delivered between 1966 and 1978,[12][13] while the T1300 was a later adoption built until 1987. The T1000 series had only a third rail shoe, while the T1300 also had a pantograph, and could be used on the Kolsås- and Holmenkoll Lines.[14] In 1995, six two-car T2000 units were delivered for the Holmenkoll Line. They were, at the time, proposed as a possible replacement for all the T1000 and T1300 stock, but were prone to technical problems. They featured both third rail shoes and pantographs.[11]

In 1996, the work to establish a financing package for new investments in public transport in

Norwegian Parliament. Oslo Package 2 allowed municipal and state grants to be supplemented by increased fare and toll road revenue to finance, among other things, new trains for the metro. The initial order by Oslo Sporveier was for 33 units (or 99 cars), and was approved by the board on 28 June 2003. The initial order cost NOK 1.6 billion, and included options for further orders. Five other manufactures had been rejected during the procurement process. Combined with other investments in the network, the new trains will allow faster travel times on the metro.[15][16][17]

In 2005, the city council voted to replace all existing T1000 and T1300 stock with the MX3000, increasing the quantity by another 30 units.

Following the 2006 decision to convert the Kolsås Line to metro standard, Akershus County Council announced that they would order five units.

tramway. Responsibility for the debt accumulated after buying the trains was to be managed by Oslo Vognselskap, while operation and management of the maintenance contracts was transferred to Oslo T-banedrift.[24]

In January 2008, an additional 15 units were ordered by Oslo Municipality, with an option for further orders later. This would allow all the eastern lines to have a 7-minute-30-second

Holmenkollen during the FIS Nordic World Ski Championships 2011. This allowed 9,000 people per hour to be transported to the sports venue.[27] In 2009, the T2000 units were taken out of service, and on 22 April 2010 the last T1300 was taken out of service, making the MX3000 the only units in traffic on the Oslo Metro.[28][29] The city council was considering ordering 15 additional MX3000 to replace the T2000, as an alternative for a NOK 50-million renovation.[30]

In November 2010, the

Accident Investigation Board Norway criticized the braking system of the trains. In 2009, there were 83 incidents where trains with locked wheels slid down steep sections of track. The Accident Investigation Board found that the metro had conducted insufficient testing of the braking system on steep slippery lines, had not adjusted the brakes satisfactorily, and had not maintained the trains and tracks sufficiently.[31] In December 2010, Oslo Vognselskap ordered another 32 three-car units, bringing the total order up to 115 three-car units. The last trains would be delivered by 2012.[32] There was political disagreement regarding the final purchase, with the Liberal Party and socialist opposition securing a majority for the purchase, while the right-winged parties voted to order 19 units. The extra trains will make it possible to run all lines except the Holmenkollen Line (Line 1) with six-car lines, compared to a situation with only three-car trains on the Lambertseter Line, the Ring Line and the Kolsås Line (lines 4, 5 and 3) would only use three-car trains.[33]

Specifications

The MX3000 is a three-car electric multiple unit built exclusively for the Oslo Metro by Siemens in

Porsche Design Studio.[34] Unlike the red predecessors, the trains are painted white with black and grey detailing. The chassis is in aluminum. A three-car train is 54.34 meters (178 ft 3 in) long; the end cars are 18.21 meters (59 ft 9 in) long each, while the center car is 17.92 meters (58 ft 10 in) long. The cars are 3.16 meters (10 ft 4 in) wide and 3.68 meters (12 ft 1 in) tall. An empty three-car unit weighs 98 tonnes (96 long tons; 108 short tons), while it with full payload weighs 147 tonnes (145 long tons; 162 short tons). This gives a maximum axle load of 12.5 tonnes (12.3 long tons; 13.8 short tons).[10][35]

Majorstuen

Each three-car unit has 138 seats, and a total capacity of 493 passengers. The height of the floor is 1.12 meters (3 ft 8 in) above the track, allowing step-free access to the platforms. There are three doors on each side of each car, measuring 1,300 millimeters (51 in) wide and 1,960 millimeters (77 in) high.[10][34][35] Unlike the older T1000 trains, the triple-car configuration allows passengers to walk between the cars. Combined with a better spatial design, it reduces the feeling of crowding.[36] The MX3000 also introduced air conditioning in the driver's cab. The units run either in single configuration (with three cars) or in multiple (with six cars).[10]

Each car is equipped with four

meters per second squared (4.3 ft/s2). In this phase, the fully loaded train uses 5.0 kiloampere. For use in areas without a third rail, such as at depots, the trains are equipped with a 110 V battery. This removes the need for shunting at the depots, and makes maintenance more cost efficient.[35][37] Energy usage is reduced by 30%, estimated to save the operating company NOK 13 million per year, compared to using the old stocks.[17][35]

T1000
and MX3000 coupled together

There are two bogies per car, each with two

suspension is steel coil spring between the axles and the bogies, with a secondary air suspension between the frame and the bogies.[10][35] The latter, which the MX3000 was the first to use on the metro, gives reduced noise, better comfort and makes it possible to adjust the height with changed passenger weight.[37]

The units are controlled by a

ergonomic than in the T1000, and the mirrors to monitor the platforms have been replaced with cameras and screens.[36]

Formation

The MX3000 carriage numbers range from 3x01–3x99 (first 99 sets) and continued with 3x100–3x115 upon delivery of the 100th set. Many of the train sets have also been given a girls' name.[38]
