The BDSeh 4/8 are three-piece meterspurige electrical low-floor - panoramic trains for mixed adhesive and gear operation of the Matterhorn Gotthard Bahn (MGB) to respond to the shuttle traffic between the car-free Zermatt and car parking in Tasch . The vehicles supplied by Stadler Bussnang are the first traction vehicles to be put into service in 2003 by the new Matterhorn-Gotthard Railway.

history

The panorama car of the Glacier Express served as a model for the intermediate car of the BDSeh 4/8.

On the short route between Täsch and Zermatt , the Matterhorn-Gotthard-Bahn operates intensive suburban traffic, whereby the passengers arriving by car often carry a lot of luggage and sports equipment. After a new car park was opened in Täsch in 1999, the transport capacity of the railway had to be increased and additional rolling stock had to be procured. The procurement of classic articulated multiple units GTW 2/6 was ruled out due to insufficient capacity, a GTW 4/8 with two traction modules turned out to be too expensive. The multiple units implemented with a four-axle intermediate car as a traction module are powerful enough to be able to carry reinforcement cars if necessary. In order to be able to offer the passengers an attractive vehicle, the middle part of the train was designed as a viewing car similar to the existing panorama car of the Glacier Express . The S in the type designation is due to the panorama compartment in the middle of the multiple unit .

technology

In the GTW, the drive is located in the traction module marked in red.

Level transition for luggage carts

The multiple units, also known as the Zermatt Shuttle at MGB, consist of the powered four-axle panorama intermediate car and two semi-mounted GTW control cars with low-floor entry, which allow the transport of up to 36 luggage trolleys . The car bodies are designed for a static compressive strength of 800 kN . The middle car with the panoramic windows is a light steel construction which, due to the limited axle load of 15 tons, required a consequent lightweight construction. The two low-floor end car bodies are classic GTW aluminum constructions with welded floor pan and door frame, screwed side walls and a glued roof. For weight reasons, a new longitudinal member profile was produced compared to the narrow-gauge GTW of the BTI , the CEV and the YSteC , which was also used in the meter- gauge cogwheel GTW of the Montserrat Railway , which was built at the same time .

The two drive bogies with the gear drive and the detachable adhesion drive were derived from the Beh 4/8 from Transports Publics du Chablais (TPC). The running bogies for the Zermatt shuttle and for the cogwheel GTW of the Montserrat railway were newly developed as the basic bogies. It is available with or without a brake gear and is also used in the ABt 421–425 articulated control car for the Bernese Oberland Railway and the Spatz for the Brünig Railway . A powerful recuperation brake acts as the main brake and works until just before the vehicle comes to a standstill. It is supplemented by a compressed air driven adhesion shoe brake and each having a band brakes on each drive axle as gear braking system 1. A spring brake in the regime adhesion and consisting of two spring-band brake per drive axle gear braking system 2 serve as parking brakes. A spin brake prevents the drive wheels from skidding if the adhesion conditions are poor . For emergencies, a self-excited resistance brake and the gear brake system 2 are available on rack sections .

The electrical equipment of BDSeh 4/8 with GTO - converters comes from the DB Class 423 . Thanks to an automatic Schwab FK-9-6 central coupling, the Zermatt shuttles can drive among themselves or with the Komet ABDeh 4/8 and ABDeh 4/10 in double traction, which enables them to be adapted to capacity requirements. Operation with a control car is also possible. Inside the vehicle there is an air conditioning system and a passenger information system .

The multiple units served as the basis for the development of the MGB Komet and the Stadler Spatz .

business

Zermatt shuttle BDSeh 4/8 in Täsch ready for departure

During the tourist season, all four railcars are in use in double traction at the weekend. In the evening and in the middle of the week, two railcars usually run alone. The ABDeh 8/8 with luggage trolleys served as a reserve until 2014 . In 2014, the three BDkt 2231–33 luggage trolley control cars were adapted for operation with the multiple units and have since served as a reserve for the Täsch – Zermatt shuttle trains in addition to luggage transport from Visp to Zermatt. Occasionally the BDSeh 4/8 have also been used as reinforcement on the route to Visp or Brig. Often the transfer is in scheduled trains for maintenance in Brig and back again.
