The Ce 4/6 is an electric locomotive that was procured by the operating group of the Bernese Alpine Railway Company Bern-Lötschberg-Simplon ( BLS ). The series comprised a total of 17 locomotives. The first 14 locomotives were purchased in 1920 and the last three in 1924. The last three machines had a slightly increased performance and a top speed that was 10 km / h higher. The locomotives were distributed as follows: 3 BLS, 2 SEB , 2 EZB , 5 GTB , 2 BSB and 3 BN . The locomotives were used freely among each other.
The last ten locomotives were converted to Ce 4/4 locomotives between 1954 and 1956 .
history
At the time of the greatest coal emergency (Switzerland has hardly any coal deposits that could be mined in its own country), the Bern government decided that the branch lines operated by BLS should be electrified. For this purpose it also ordered the locomotives for these railways, which earned the locomotives the nickname “ decree mills” . The locomotives were supposed to replace the small steam locomotives as lightweight universal machines. The locomotive was the small, less powerful version of the SBB Be 4/6 built at the same time , but differed from it in many details.
Technical
The locomotive is built according to the same construction principles as the crocodiles , although it lacks the typical long stems, which is why it is seldom counted among the crocodiles. The pulling and pushing devices are attached to the bogie, and the two bogies are articulated to one another via the car body . It is therefore a hybrid form between a frame locomotive and a bogie locomotive . A drive motor is installed in each bogie, which drives a jackshaft via gear wheels, slotted coupling rods connect these with the two drive axles; a running axle is arranged against the end of the locomotive. The running axle was necessary because not all routes allowed such a high axle pressure as would have been the case with the desired performance with a running axle-less design. When all routes were adjusted, it was decided to convert ten locomotives, which happened between 1954 and 1956. To do this, the two running axles and the two small cab porches were removed. The locomotives were up to 10 tons lighter and the driving behavior was not negatively affected by the conversion. The converted locomotives were redrawn as Ce 4/4.

The Ce 4/6 307 has been preserved as a historic locomotive and was exhibited in the Lucerne Museum of Transport for a long time.
The Ce 4/4 312 is preserved at the Club del San Gottardo , in the condition as it was last used at the SZU. In March 2013, the Ce 4/4 312 was transferred to the holdings of the BLS Foundation "Pioneers", which takes care of the historic BLS vehicles.
The transformer of the Ce 4/4 316 was installed in the SBB De 6/6 15301 on the occasion of its revision in 1995 and 2008 . The rest of the 316 was then scrapped.
Before being scrapped, the 310 and 316 were still doing shunting work in the Bönigen workshop , although they only had one functioning engine.
