The Stadler GTW is an articulated railcar for local transport made by Stadler Rail of Switzerland. GTW stands for Gelenktriebwagen (articulated railcar).

Description[edit]

Stadler GTW is family of vehicles which differ externally, in the various designs of the head of the vehicle (from angular to streamlined), and also in the different designs and power units that drive them. They also come in different gauges and as rack railway vehicles. The basic version is the GTW 2/6, a railcar which conforms to UIC standards. "2/6" means "two of six axles are powered". The GTW 2/6 is used for example by Deutsche Bahn as Baureihe 646 (Series 646) and by Swiss railways as RABe 526.

The basic concept is rather unconventional: the car is driven by a central "power module", also known as a "powerpack" or a "drive container", powered on both axles. Two light end modules, each with a bogie, rest on the power module, which produces useful traction weight on the driving axles. The end modules also use the space very effectively, although the railcar is divided into two halves by the power module. Most units have a path through the drive container for passenger access. The end modules can be delivered with standard pulling devices or buffer gears, or with central buffer couplings. They are built with a low-floor design except above the bogies and at the supported ends (more than 65% of the railcar is low-floor). All of the usual comforts to be expected in a modern local network railcar are provided, such as air conditioning, a multi-purpose room, vacuum toilets (in a washroom suitable for the disabled) and a passenger information system. The GTWs can be Diesel-electric or electric-powered (via overhead wires or third rail). 551 units have been sold to date[when?] and are in use in Italy, the Netherlands, Switzerland, Slovakia, Germany, and the United States.

Propulsion[edit]

There are diesel propulsion modules with 550 kW (740 hp) (since 2003) with 2 x 375 kW (503 hp) = 750 kW (1,006 hp) power available, and electric propulsion modules with 600 to 1,100 kW (800 to 1,480 hp). IGBT based traction converters together with asynchronous motors are used as drive units. The traction converters are manufactured by ABB at their site in Turgi, Switzerland and the motors by TSA Austria.

By inserting a middle car (also with only one bogie) on one side of the propulsion module, the GTW 2/6 is expanded to GTW 2/8. Instead of the middle car, another drive module can also be inserted. Between the two modules are then either a trailer passenger car (GTW 4/8) or two medium cars and partitions (GTW 4/12). For operational flexibility up to four GTWs of the same pattern can be operated as a multiple unit.

Applications[edit]

USA[edit]

New Jersey[edit]

GTW trains are also planned to operate on SNJLR's Glassboro–Camden Line, currently in development.

Central Texas[edit]

Main article: Capital MetroRail

The Capital Metropolitan Transportation Authority (CapMetro) in Austin, Texas, uses six Diesel rail vehicles of the type GTW 2/6 on its 32-mile (51.5 km) red line from Leander to Downtown Austin.

Denton County, Texas[edit]

The Denton County Transportation Authority (DCTA), announced on May 20, 2009, that it would purchase 11 GTW 2/6 articulated diesel multiple units (DMUs) for DCTA’s 21-mile (34 km) corridor from Denton to Carrollton. This line connects with the Dallas Area Rapid Transit (DART) Green Line which extends from the Pleasant Grove neighborhood in southeast Dallas to northern Carrollton. The contract includes an option for up to 25 additional GTWs.[1]

France[edit]

The Panoramique des Dômes in France uses 4 GTW 2/6 since opening in 2012.[2]

Italy[edit]

In Italy GTW are used by some regional railways, and called ATR:

Switzerland[edit]

The SBB-CFF-FFS (Swiss Railways) use the GTW 2/6 (and soon GTW 2/8) in its electric version branded Thurbo for various routes out of Zürich.

Netherlands[edit]

Arriva train in Bunde

The multinational transport company Arriva uses the diesels on the lines: Leer (Germany) - Groningen, Nieuweschans - Groningen, Delfzijl-Groningen, Leeuwarden - Groningen, Roodeschool - Groningen, Veendam - Groningen, Zuidbroek - Groningen, Leeuwarden - Sneek, Leeuwarden - Stavoren, Leeuwarden - Harlingen Haven. From December 2012, Arriva is also using diesel GTW's on Arnhem-Winterswijk, Winterswijk-Zutphen and Zutphen-Apeldoorn. The electrified GTW are used on the lines Dordrecht - Geldermalsen and since December 2012 also on Zwolle - Emmen.

Veolia Transport used the electrified GTW on the lines Kerkrade Centrum - Heerlen - Maastricht Randwyck, Heerlen - Maastricht, and the diesels are used on the lines: Roermond - Venlo - Nijmegen.

Connexxion uses one electric GTW for the line: Barneveld Centrum - Amersfoort and is using 9 diesel GTW's for the Breng concession starting December 2012.

Models[edit]

HO scale (1:87)[edit]

In 2011, German model manufacturer Piko introduced a model of the GTW 2/6 in both Diesel and Electric versions in a wide range of liveries including DB-AG Regio red, SBB-CFF-FFS (Swiss Railways) Thurbo and Arriva's Spurt livery. These models are in their "Expert" range and retail for around 200 Euro - accessories available include DCC decoders, interior lighting kits and sound kits for both Diesel and Electric variants. The model themselves can be obtained in DC/DCC 2-rail and AC 3-rail Märklin compatible versions.

Besides, the Swiss model manufacturer (HAG) also produces the higher end GTW 2/6 and GTW 2/8 in THURBO livery which is of metal body construction, metal pantographs, lit destination signs as well as LED interior lightings with figurines in the interior of the train. Also optional are the onboard sound option which features the GTW 2/6 / GTW 2/8 being factory-fitted with Loksound V4.0 sound decoder that can support up to 15 functions.
