Artic, also styled as ARTIC by the manufacturer, is an articulated low-floor tram model designed and manufactured by Transtech Ltd in Finland.


In December 2010 the design was included in the winning tender to deliver 40 new trams to the Helsinki City Transport (HKL), the municipal tram operator of Helsinki Regional Transport Authority (HSL), with an option for 90 units more. The winning bid was worth €113 million, which makes the unit cost of the initial agreement €2.8 million per tram.[1]

The first unit was rolled out in the summer of 2013 and taken to line operation for testing purposes in the autumn of 2013. The second unit was delivered in November 2013, and these two units will be thoroughly tested before the manufacturing of the remaining 38 units will begin in late 2015. All the units will be delivered by 2018.[2]

The technical design is based on free-turning bogies, which is rarely seen in low-floor trams until recently. The tram network in Helsinki, which has many sharp turns and switches and steep gradients, poses a challenge for many low-floor tram designs, which made the Variotram design ill-suited for the network. To remedy these problems, Helsinki City Transport itself made preliminary design for a new low-floor model, and this design work was also the foundation of the Artic tram. The design claims to move more smoothly and quietly in sharp turns and switches and wear down the tram wheels less.[3]

All the axles (eight in the first model) in Artic are powered by an independent motor of 65 kW, and the tram is tested for speeds up to 80 kilometres per hour (50 mph). The tram is equipped with a regenerative braking system. In the Helsinki version the energy is used for heating, but the design is also ready to be equipped with supercapacitors.[4]

By June 2018, HKL has used all three of its options for extra units. First option was used in 2016 for 20 additional units (numbers 441–460) for the existing Helsinki network and they are to be delivered by the end of 2018. Second option was also used in 2016 for 29 additional units (numbers 601–629), but this time for the future Raide-Jokeri light rail (construction is due to begin in 2019) connecting the cities of Helsinki and Espoo. The Raide-Jokeri Artic XL [5] trams differ from the rest in many ways: They are 34.5 metres (113 ft) long, bi-directional, they have a capacity of 214 passengers (78+4 seated, 136 standing, 4 persons/m2), they have their own unique design and they consist of five modules instead of three in the basic model. The Artic XL trams can also be lengthened to be up to 44 metres (144 ft) long with a capacity of 287 passengers (100+8 seated, 187 standing). The first Artic XL tram will be used in the existing Helsinki network for testing and will be delivered around 2019–2020, while the production of the series will begin sometime in the early 2020s. The last option was used in June 2018 for 10 more units (numbers 461–470) of the basic Artic model for the expanding network in the coming years. These vehicles will be delivered by the end of 2019. That makes a total of 99 Artic trams ordered and/or delivered for Helsinki City Transport (HKL).


Bi-directional Artic trams are also to be delivered for the city of Tampere in Finland for the new light rail system under construction and due to open in 2021. A total of 19 units (with an option for an additional 46 units for future expansions) are to be delivered during 2020 and 2021 for the city-owned company Tampere Tramway Ltd (Tampereen Raitiotie Oy), which will own, maintain and develop the network and rolling stock. The Tampere light rail has a standard gauge of 1,435 mm (4 ft 8 12 in), so the Artic trams for Tampere will be 2.65 metres (8.7 ft) wide. The vehicles will be 37 metres (121 ft) long and can be lengthened to be up to 47 metres (154 ft). The Artic light rail vehicles for Tampere will have a capacity of 264 passengers (64+40 seated, 200 standing, 4 persons/m2). [6]


In June 2018 won tender for Rhein-Neckar-Verkehr and will deliver 80 bi-directional Artic trams for its tram system. The contract includes an option for 34 additional vehicles. The contract consists of 31 30 m trams, 37 40 m trams and 12 60 m trams, longest tram in the world at the moment.[7][8]
