The Ge 4/4 1 is the Appenzeller Bahnen's only locomotive .
History
When the Appenzeller Bahn's freight traffic was switched to roll stands in 1978, the ABe 4/4 43 multiple units and later the ABDeh 4/4 1–5 were used. However, the railcars were reaching the limit of their useful life and it was time to get a new one.
The specifications of the locomotive stipulated that it must be designed for the transport of freight trains and passenger trains. At the time, there was no comparable vehicle in use for such a task on other railways with the same power system that could have been replicated. Therefore, a new vehicle was designed in which components from other vehicle series were used as far as possible. To transport passenger trains, the locomotive must also be remotely controllable from the existing control car.
The order for development and production was awarded to a consortium consisting of Stadler Rail Bussnang , the Swiss Locomotive and Machine Factory and ABB .
Technical
SLM supplied the two narrow-gauge bogies that correspond to those of the RhB Ge 4/4 III . The three-phase asynchronous traction motors from ABB are also identical to the RhB locomotive. The box is a one-off production by Stadler Fahrzeug AG, Bussnang, the pneumatic equipment and the luggage compartment doors are identical to the BDe 4/4 II 34–35, new 44–45. The electrical equipment comes from ABB and corresponds to "half" an RhB locomotive. The drive motor control is built with GTO thyristors and has been adapted to direct current operation, as it is e.g. B. is also used with the MOB Ge 4/4 . The cab equipment corresponds to the AB shuttle trains.
Since the freight traffic on roller stands has meanwhile been discontinued, the higher-mounted buffers for standard gauge wagons were removed in 2010.
A luggage compartment with 8 m² loading area and a maximum load weight of 3 t is built into the locomotive for the transportation of passenger trains.
commitment
Originally procured for freight transport on trolleys, the Ge 4/4 1 now operates almost exclusively as a locomotive for a shuttle train. In 2012, the locomotive was given an anniversary paint job for the 500th anniversary of Appenzell's membership in the Swiss Confederation.
