Stadler Citylink
Stadler opened a new factory in the United States in 2016, which is in the process of building up to 80 Citylink vehicles for service in Salt Lake City beginning in 2028.
Some Citylinks are fitted with transformers to provide dual-voltage capability, such as those used in Sheffield, which run at 750 V DC on the city's tram network, but with the ability to also use 25 kV 50 Hz AC in the future, as is standard for British railways.
[2] Eight NET 2012 tram-trains similar to the Karlsruhe models, with options for two more, were ordered by Verkehrsverbund Mittelsachsen (VMS) for planned use on the Chemnitz Bahn network from 2015.
[6] As part of the same deal, Albtal-Verkehrs-Gesellschaft (AVG), the other primary operator on the Karlsruhe Stadtbahn network, ordered their own Citylinks for the first time, complementing those already in the fleet of VBK.
The first Citylink (as Hungarian Class 406 001) was delivered in January 2021, and the testing of the 3-car units began in early March on the freshly rebuilt line between the two cities.
These are fitted with a diesel engine only, due to a lack of railway electrification in the region, and a revised front end crash structure compared to European models.
Nine Vossloh Citylink tram-trains were ordered by Ferrocarrils de la Generalitat Valenciana for use on the Alicante Tram network's lines 1 and 3.
Serveis Ferroviaris de Mallorca ordered six Citylinks in 2011 for operation on the new Manacor to Artá railway line, which was planned to reopen in 2012.
[3] It was announced by the Department for Transport in 2008 that Sheffield would be used as the location for the first ever tram-train in the United Kingdom as part of a nationwide pilot scheme.
The Supertram Citylink design is based on that of the newer NET 2012 trams ordered by Karlsruhe and Chemnitz in Germany.
The Supertram Citylinks are dual voltage vehicles, capable of operating at the 750 V DC overhead electrification used on the Supertram network, and the 25 kV 50 Hz AC overhead electrification being installed on the Dearne Valley line to Rotherham and used elsewhere on the National Rail system.
These vehicles are the first to feature "smart-electrification" which allows Discontinuous electrification with permanently earthed sections around restricted structures.
These Tram-Trains will switch to battery mode under bridges and tunnels negating the need for costly reconstruction of over 50 structures on the South Wales Metro.
The vehicles are planned to enter service by 2028 on the TRAX light rail system in the Salt Lake City area, which has been home to a Stadler plant since 2016.
