The MGB Comet (manufacturer spelling: KOMET) for " ko mfortabler Me terspur- T riebzug" are meterspurige electric low-floor - Panorama multiple units of the Matterhorn Gotthard Bahn (MGB) in Switzerland for mixed adhesion and rack operation , made by Stadler Bussnang . The trains have 1st and 2nd carriage classes as well as a luggage compartment and run as three and four-part units with the designations MGB ABDeh 4/8 and ABDeh 4/10 . Four of the eight or ten axles are driven.

history

Multiple unit ABDeh 4/10 2011 in Brig , coupled with an ABDeh 4/8. The powered intermediate car is in third position from the front.

To increase the transport capacity on the Visp – Zermatt line after the opening of the Lötschberg base tunnel , MGB needed new, comfortable trains for adhesion and gear drive. The tight deadlines were not enough to develop a completely new vehicle concept. The Komet were technically developed from the BDSeh 4/8 shuttle multiple units , whose concept, like that of the Komet , is derived from the Stadler GTW . Unlike the GTW, the electrical equipment is not located in the short two-axle middle section, but underfloor in the four-axle panorama car. Compared to the Zermatt shuttles, the length of the end and intermediate cars has been optimized for the largest possible passenger capacity.

Two three-part and three four-part multiple units were delivered in 2007 and 2008, followed by another six short and one long train in 2014. The trains are designed in such a way that they can be expanded into five-part compositions.

... at the other end of the train there is a luggage compartment.

Each multiple unit consists of a high-floor, entry-free, four-axle panorama multiple unit. On one side there is an end car with a running bogie and low-floor access - on the other hand there is an end car on the three-part train and a non-powered intermediate car and an end car on the four-part variant. The railcar has two two-axle bogies with one drive motor per axle. The drive takes place in pure adhesion mode via the four axes of the motor bogies and in cogwheel mode additionally via four gears for the racks of the Abt system used at MGB . The semi-mounted elements each have only one running / braking bogie at the outer end of the car and are supported on the other end of the following car. All bogies are air-sprung. The boxes for the end and intermediate cars are made of large aluminum profiles, some of which are welded and some are bolted. The high-floor railcar is made of steel and has panoramic windows. The electrical equipment corresponds to that of the shuttle trains.

Because the Komet trains travel much longer than the Zermatt shuttles, they are much more comfortable. They were given a new interior design and have closed toilets, air conditioning and a passenger information system .

Thanks to an automatic central buffer coupling of the type FK-9-6 from Schwab Verkehrstechnik , the multiple units can run in multiple control - also with the shuttle multiple units BDSeh 4/8 and the four low-floor articulated control cars ABt 2131-34 - which enables them to be adapted to fluctuations in demand. In 2014, Stadler adapted the BDkt 2231–33 “luggage trolley control car” for operation with the Komet. They are used to transport luggage and also serve as a reserve for the Täsch - Zermatt shuttle trains .

The multiple units can run on the entire MGB route network, but only the three-part ABDeh 4/8 are permitted for the 179 ‰ steep Schöllenenbahn Göschenen – Andermatt. On a 125 ‰ gradient, the maximum train weight is 150 tons.
