The BCFeh 4/4 1–3 are electric railcars with a baggage compartment for mixed cogwheel and adhesion operation, which were acquired in 1908 for the opening of the meter-gauge Monthey-Champéry-Morgins Railway (MCM). The BCFeh 4/4 6 is a 1909, just one year after the opening of operations, an opportunity purchase of a largely identical railcar, which was originally intended for the Stresa-Mottarone-Bahn (FM) in Italy. The railcars designed for the Strub rack and pinion system were built by the Schweizerische Industrie-Gesellschaft in Neuhausen am Rheinfall , with the electrical equipment coming from the Alioth electricity company in Münchenstein and the bogies from the Swiss Locomotive and Machine Factory (SLM) in Winterthur . The railcar BCFeh 4/4 6 has been preserved on the Blonay – Chamby (BC) museum railway in western Switzerland.
construction
On delivery, the railcars were characterized by the two bogies with rod drive, a central entry and wooden frame windows, which are not designed in the form of two narrow twin windows, but rather as a large window with two panes of glass separated by a vertical wooden walkway. It is also typical for these railcars that the central buffer coupling with a simple screw coupling located below is integrated in an extension of the underframe. Otherwise they have the usual construction at that time with a base and a sheet metal structure.
One motor for the adhesion drive and one for the gear drive are housed in each of the two bogies. The former drives one of the two axles via a single gearbox, from which the other axle is driven via rods attached outside of the bogie frame. The other motor drives the gear loosely mounted on the other axis via a double transmission.
In adhesion mode, only the two motors provided for this purpose are in operation. When used in gear operation, all four motors are in operation, whereby the adhesion motors can only be used in series because of the significantly slower travel speed. As a result, motor coaches number 1–3 are available in 2 × 75 HP adhesion operation, a total of only 150 HP. In gear operation there are 2x75 HP for the two motors of the gear drive and half of 2 × 75 HP for the motors of the adhesion operation, a total of 225 HP. With railcar number 6, 190 hp are available in adhesion mode and 285 hp in rack and pinion mode based on the same mathematical principles. All four railcars have a compressed air and resistance brake. The braking equipment was supplemented by two hand brakes that acted independently on the gear wheels and the drive wheels of the adhesion company.
history
In 1916, the upholstered class compartment was discontinued in favor of a larger luggage compartment at number 3 in its own workshops in Monthey, and from then on the designation was CFe 4/4. On the occasion of the class reform, the number 6 was renamed from BCFeh 4/4 to ABFeh 4/4. In 1962, the designation of number 6 changed again from ABFeh 4/4 to ABDeh 4/4 in order to receive the original short-term designation BCFe 4, which was valid at the beginning of electric traction in Switzerland, in 1975 as a historic locomotive.
They kept their original numbering even after the merger of the Aigle-Ollon-Monthey-Bahn and the Monthey-Champéry-Morgins-Bahn to form the Aigle-Ollon-Monthey-Champéry-Bahn in 1946.
Areas of application
The railcars ran almost exclusively on the Monthey – Champéry railway line, which had several rack sections. Only motor coach number 6 was used as a service motor coach on the Aigle – Ollon – Monthey line following the extensive renewal of the vehicle fleet in 1954.
The vehicles were painted light gray / white throughout the entire service life. Only the railcar 6 had from 1954 at the latest, the exact time of the repainting is not recorded, and until 1975 a green / cream paint job.
Whereabouts
After the delivery of the new railcars for mixed adhesion and cogwheel operation BDeh 4/4 501 to 504, railcars number 1 to 3 were taken out of service in 1954 and then broken off. The slightly stronger and younger railcar number 6 has been preserved. Although it was also taken out of service in 1971, it was put back into service in 1975. After it was repainted in its original colors by the Blonay – Chamby museum railway, it was taken over as a donation after a last trip on its original railway line in 1976. On the occasion of the 100th anniversary of the Aigle-Ollon-Monthey-Champéry Railway in 2008, it returned to its regular route and was refurbished at the Transports Publics du Chablais (TPC) in En Châlex together with the BC 2 10 passenger car from 1908 .
