The Deh 4/4 is a narrow-gauge luggage railcar series of the former Brig-Visp-Zermatt-Bahn (BVZ), today Matterhorn-Gotthard-Bahn (MGB), for adhesion and cogwheel operation . The series includes four vehicles (numbers 21 to 24) and the mechanical part is based on the FO Deh 4/4 I , but has a different electrical structure.

history

The increasing traffic, especially the Täsch – Zermatt shuttle service, called for an expansion of the BVZ's fleet of locomotives, which at the beginning of the 1970s consisted of only six 40-year-old locomotives and five articulated or double railcars. Since the concept of the Deh 4/4 shuttle trains worked well for the FO, the Brig-Visp-Zermatt-Bahn also ordered four multiple units, intermediate and control cars in 1973, which were delivered in 1975 and 1976. While the mechanical part of the railcar was largely kept unchanged, a thyristor control made by SAAS was installed in the electrical part, analogous to the SBB series RABDe 8/16 , which increases the performance compared to the FO vehicles. Control and intermediate cars were also of the same design ( SIG-Einheitwagen I ) as those of the FO, but longer.

technology

Comparison of both sides of the car body of the Deh ex BVZ (above) and ex FO (below)

To save weight, the car body is made of light metal. The equipment cabinets with the electronic and pneumatic equipment are located in the luggage compartment in the middle. The transformer is located under the car body, the bogies each have two motors.

The vehicle is electrically constructed with phase control (thyristor control). It has a resistance brake, but no recuperation brake.

commitment

The former BVZ vehicles were used between Zermatt and Brig both with shuttle trains and with towed passenger trains and freight trains. They have also been used on Oberalp since 2006, but they lack the braking equipment for the Schöllenen. These railcars can carry five passenger cars to Zermatt and Oberalp. In summer, shuttle trains are set up for the Oberalp route, where the vehicles within the composition are connected to the automatic + GF + coupling (GFN). In winter, these vehicles mostly carry the shuttle train compositions used as sports trains and the car transport trains between Andermatt and Sedrun.
