The BCFhe 2/4 were railcars in operation on the Schöllenenbahn (SchB) and the Furka-Oberalp-Bahn (FO). The Schöllenenbahn put the BCFhe 2/4 No. 41 into operation in 1941, as did the BCFhe 2/4 No. 42–43 wagons of the Furka-Oberalp-Bahn in 1941, and the two cars in the following year too CFhe 2/4 44–45 car started up in 1942.

The Schöllenenbahn has been operated with direct current since it started operating in 1917, while the FO only used ten HG 3/4 steam locomotives and two CFm 2/2 petrol railcars until 1941 . When the Andermatt-Disentis line was electrified in 1941 for strategic reasons and the AC system (11 kV, 16 2/3 Hz) that had already been introduced by the Rhaetian Railway was used, the opportunity was used to adapt the Schöllenenbahn's power supply in order to continue to use the community station To be able to use Andermatt . Together, the two railways ordered three and later, following the decision to electrify the Andermatt-Brig line, two more railcars. These were delivered without a second-class compartment, but were adapted to the other vehicles in 1946 by converting the small third-class compartment between the entrance and the driver's cab into a second-class compartment. With the abolition of the third class, the railcars were renamed ABFhe 2/4 in 1956. In 1966 it was renamed ABDhe 2/4, then in 1969 ABDeh 2/4. After the first-class compartments were converted into second-class compartments between 1974 and 1978, the railcars were designated as BDeh 2/4.

From the 1970s onwards, they mostly ran as a short shuttle train together with a control car from the ABt 4191–4194 series , after motor car 41 had been running frequently with the BCFt 30 control car in the Schöllenen since 1943 .

ABDeh 2/4 43 was badly damaged in a collision near Fürgangen in 1971 and was repaired again in 1974, with the destroyed driver's cab on the Brig side being removed and converted into a second class compartment with 16 seats together with the former first-class compartment. After that, this vehicle could only be used in shuttle train service with one of the ABt control cars.

Railcar 41 wore the Schöllenenbahn's blue and cream colors until 1962 and was repainted in the dark FO red after the merger between SchB and FO. As part of tests for a new look for the railway in 1978, the railcars 44 and 45 were given test markings. From 1980 these were replaced by new paintwork in a lighter shade of red with white vertical stripes.

technology

The narrow-gauge railcars each have a combined, firmly coupled adhesion and gear drive bogie under the luggage compartment on the Göschenen / Disentis side and a running bogie under the driver's cab on the Brig side. They can therefore be used on the adhesion and gearwheel sections of the railway up to Maximum incline of 179 ‰ possible. The drive takes place via two cradle bearing motors which are installed between the axles.

The self-supporting car body is made of steel, with the floor frame being designed to be particularly strong because of the large tensile and compressive forces on the steep section of the Schöllenen and the heavy transformer. To save weight elsewhere, roof structures and doors made of aluminum were used.

Because of the special safety requirements in steep sections on the Schöllenen route, the vehicles have four different braking systems: an electric service brake, a combined compressed air and vacuum brake that acts on the wheels and the brake gear, a compressed air brake for the two drive gears and a spring-loaded brake as a parking brake.

Whereabouts

In 1993, railcars 42 and 44 were scrapped, as was No. 43, which was badly damaged by the flood in Brig caused by the Saltina on September 24, 1993. In 1995 no. 43 was canceled, 42 and 44 followed in 2000. In 2001 the penultimate railcar no. 45 was taken out of service and canceled. Of the original five railcars, only number 41 has survived. This vehicle has been parked in the MGB depot Glisergrund since 2001 and was handed over to the Furka Mountain Line Steam Railway (DFB) on October 12, 2010 . It was parked there in Realp and has been waiting for new missions ever since. The vehicle was added to the fleet of the MGBahn-Historic association, but the railcar is still in Realp in 2018.
