The electric railcar delivered to the Sihltalbahn (SiTB) in 1930 was designated as CFe 3/4 . The railcars were manufactured by the Swiss Wagon Factory Schlieren (SWS) and Maschinenfabrik Oerlikon (MFO).
Technical
The mechanical part and the car body were supplied by SWS, the electrical equipment by MFO.
It was a further development of the CFe 2/4 delivered in 1924 , and like the De 3/3 it had three traction motors. Compared to the CFe 2/4 it had a 2.4 meter longer car body, which made it possible to move the electrical equipment boxes from the car floor to the interior of the car. Electrically, it largely corresponded to the De 3/3, whose replacement vehicle it was. There was a pantograph on the roof above each bogie.
The top speed was 50 km / h from the start.
After a collision, it was rebuilt and, now able to operate with the new control car in multiple control, it was painted red again in 1967.
Redrawings
When the vehicle was delivered, the FCe 3/4 90 was not written in accordance with the standards, but it was usually correctly listed as CFe 3/4 in the rolling stock statistics.
Redrawings: 1956 BFe 3/4 90, 1963 BDe 3/4 90, 1973 BDe 3/4 71
commitment
The railcar was used rather cautiously. In addition to the alternatively guided freight trains, it was mainly used in front of the heavy subscription trains and on the Sunday before the excursion trains when the CFe 2/4 were at their performance limit.
From 1971 it was purely a reserve vehicle, and from 1978 it only served as a preheating system in Zurich Selnau.
Whereabouts
After the vehicle was not for sale, it was canceled in 1989.
