Variobahn
Edit

The Variobahn, formerly known as the Variotram, is a German-designed model of articulated low-floor tram and light rail vehicle. Since its introduction in 1993, the Variobahn has been manufactured variously by ABB, Adtranz, Bombardier Transportation, and since 2001 by Stadler Rail. As of 2009, 254 trams have been ordered, with an additional 110 on option. A unit costs about €2.5 million. Operators include the Graz Holding, the Bergen Light Rail, the Chemnitz Tramway, Verkehrsverbund Rhein-Ruhr, the Helsinki Tramway, the Rhine Neckar Area Tramway and London Tramlink.

1. History

1.1. Prototypes and Early Deliveries

The Variotram was first developed by ABB Asea Brown Boveri at Henschel and a prototype was launched in 1993 for the Chemnitz tramway in Germany, operated by Chemnitzer Verkehrs-Aktiengesellschaft (CVAG). The serial delivery, with minor modifications, was made between 1998 and 2001—bringing the total number of units for Chemnitz to thirty. Of these, twenty-four were operated by CVAG and six by City-Bahn Chemnitz. In 1995, ABB's train division merged to become Adtranz. One prototype the following year sold to the Duisburg Stadtbahn, but serial production was never initiated for Duisburg.[1][2]

In 1996, six trams were delivered to serve on the light rail between Mannheim, Heidelberg and Weinheim, Germany, operated by Oberrheinischen Eisenbahn-Gesellschaft. From 2001 to 2007, it ordered additional 20 trams. These were supplemented in 2002 by 8 trams for the Heidelberg Tramway, and in 2001–07 by 16 trams for the Mannheim Tramway.[1] In 1996 the Sydney light rail system, in Australia, took delivery of seven trams, which were built in Dandenong, Victoria. All were withdrawn by mid 2015 and the remaining 6 put up for sale.[3] The Sydney trams did not sell, 5 were scrapped in early 2018, and the last built no 2107 was transferred to the Sydney Tramway Museum in October 2018 for preservation.[4]

1.2. Helsinki

Forty Variotrams were delivered to Helsinki City Transport (HKL), Finland, between 1998 and 2003 for use on the Helsinki tramway, at a cost of €76 million.[5] These trams were built by Transtech (who later produced the newer Artic models) in Otanmäki under a technology transfer agreement with Adtranz. During this time the company was acquired by Bombardier, who inherited the design in 2000, making the Helsinki trams the only Variotrams to be produced under the Bombardier name.

In service, the Variotrams were found to be ill-suited for Helsinki's tram network, having suffered from numerous technical problems, including cracks in the bogies and vehicle body shells. Before 2009 often less than half of the trams have been in working condition.[6][7] HKL considered returning the trams to Bombardier as unsatisfactory, but after a long series of negotiations a compromise was reached in May 2007, when the responsibility for maintaining the trams was transferred to Bombardier.[7] The contract agreed in May 2007 states that, from May 2008 onwards, if more than four Variotrams in Helsinki are not in operational condition, Bombardier must pay a daily fine to the HKL for every non-operational tram. If more than eight trams are in non-operational condition, HKL has the right to cancel the contract and return the trams to Bombardier, who are obliged to return the €76 million that HKL paid for the trams.[7] In order to cope with the requirements of the agreement, Bombardier established its own maintenance workshop in Helsinki in mid-2008, located in the premises of the former VR Group electric locomotive workshop in Pasilan Konepaja.[8]

In August 2017 a contract was agreed after long negotiations between HKL and Bombardier to cancel the purchase of the Variotrams. Bombardier will pay HKL 33 million euros in compensation for the shorter than originally contractually agreed 40 year lifetime of the trams. HKL will return the trams to Bombardier from 2018 on.[9]

1.3. Stadler

Stadler built Variobahn for the Bergen Light Rail. https://handwiki.org/wiki/index.php?curid=1980474

To concentrate on its own Flexity family of vehicles, Bombardier reached an agreement with the European Commission where Bombardier would divest the Variotram division to Stadler Rail of Switzerland.[10]

Stadler subsequently renamed the tram as Variobahn and has since secured several contracts,[1] delivering:

  • 8 trams for use on the Ludwigshafen tramway
  • 30 trams for the Bochum–Gelsenkirchen tramway
  • 8 trams for the Nuremberg tramway
  • 14 trams for the Munich tramway[11]
  • 12 trams for the Bergen Light Rail
  • 45 trams for the Graz tramway
  • 19 trams for the Potsdam tramway[12]
  • 12 trams for the Croydon Tramlink in London[13][14]

As of 2009, a total of 254 Variobahn trams have been ordered, with an additional 110 on option. A unit costs about €2.5 million.[1] Stadler builds its trams at their Pankow plant in the northern suburbs of Berlin and the Stadler facility at Velten north of Berlin.

Problems in Munich

In December 2014, MVG took seven of its Variobahns out of service due to cracks in vehicle bodies. By January 2015, all Variobahns had to be withdrawn for repairs. MVG chose not to exercise options to buy any more Variobahns, and turned to Siemens to supply its next generation of trams.

Variobahn trams for Croydon Tramlink

Six units were ordered for Tramlink by Transport for London in August 2011 at a cost of £16.3 million [15] with an option for up to 8 more trams.[13] The London Borough of Croydon council contributed £3m to the cost.[13]

Three of the Croydon trams were diverted from a batch of five which were ordered for the Bybanen line in Bergen, Norway .[15] Stadler built these earlier than the contractual delivery date to make use of free capacity at its factory. Three more trams were built directly for Croydon, plus three trams for Bergen to replace the ones which went to Croydon.[15]

Initial testing was carried out in Chemnitz, Saxony.[16] The first tram, 2554, was delivered to Croydon on 24 January 2012[17] and carried its first passengers on 30 March 2012.

2. Specifications

The Variotram is a low-floor light rail tram designed for city center operation. Since customers consist of both existing and new systems, and their specifications vary, the Variotram has flexibility in specifications. It can be built as uni- or bi-directional, with 70 or 100% low floor. Rail gauge can be 1,435 mm (4 ft 8 12 in) standard gauge or 1,000 mm (3 ft 3 38 in) metre gauge. Width options include 2.3 metres (7 ft 6 12 in), 2.4 metres (7 ft 10 12 in), 2.5 metres (8 ft 2 38 in) and 2.65 metres (8 ft 8 38 in). The length varies with either three, four, five or seven articulated modules. The floor height is 350 millimetres (14 in) over the rail. The seating and standing arrangements are flexible, and the trams feature 1,350 millimetres (53 in) wide doors. The tram has hub motors on all wheels, thus eliminating the need for axles and bogies. These compact motors are the key to the low-floor concept, since they can be placed under the seating. This allows the full length of the tram to be step-free accessible from the platforms.[18]

Several of the configurations of the trams are customizable to fit each tramway. In addition to the four possible widths and choice of gauge, the trams can be custom-built for the necessary length.[1] Trams are built modally, so that they can later be rebuilt or extended.[19] All trams built so far have five modules and twelve wheels. The trams are available with four motor settings: four or six wheels powered with 95-kilowatt (127 hp) motors, or eight or twelve wheels with 45-kilowatt (60 hp) motors. Of the models built so far, the length has varied from 24.4 to 42.8 metres (80 to 140 ft) (Helsinki and Mannheim, respectively). Similarly, tare weight varies from 35 to 50 tonnes (34 to 49 long tons; 39 to 55 short tons). Seating capacity varies between 38 (Graz) and 100 (Heidelberg), while standing capacity peaks at 193 for the Duisburg version.[1]
