Description
Stadler GTW is family of vehicles which differ externally, in the various designs of the head of the vehicle (from angular to streamlinedStreamliner
A streamliner is a vehicle incorporating streamlining in a shape providing reduced air resistance. The term is applied to high-speed railway trainsets of the 1930s to 1950s, and to their successor "bullet trains". Less commonly, the term is applied to fully faired recumbent bicycles...

Rail gauge
Track gauge or rail gauge is the distance between the inner sides of the heads of the two load bearing rails that make up a single railway line. Sixty percent of the world's railways use a standard gauge of . Wider gauges are called broad gauge; smaller gauges, narrow gauge. Break-of-gauge refers...

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
Bogie
A bogie is a wheeled wagon or trolley. In mechanics terms, a bogie is a chassis or framework carrying wheels, attached to a vehicle. It can be fixed in place, as on a cargo truck, mounted on a swivel, as on a railway carriage/car or locomotive, or sprung as in the suspension of a caterpillar...

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

Propulsion
There are diesel propulsion modules with 550 kW (since 2003) with 2x375 = 750 kW power available, and electric propulsion modules with 600 kW to 1,100 kW. All drive modules work with IGBT pulse inverters. The converter plant stems from ABB and Turgi manufactured at the site.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.
