The Compagnie de l'Ouest Suisse ( OS ) acquired in 1858 a total of 5 Tender steam locomotives of the type B 2/3 , as Gemischtzuglokomotiven were constructed. The locomotives were supplied by the Cail & Cie machine factory in Paris, the tenders by the Ateliers d'Oullins.
This is the third series of this machine type for the OS, for the other locomotives of this type see B 2/3 .
Technical
The machine was one of the Stephenson long boiler type. The fire box was located behind the driving axles. The machine had an inner frame. On the boiler there was a Crampton regulator housing above the barrel axis, the slides in it were operated with rods above the boiler. The levers for this were arranged above the boiler in front of the driver's cab. The driver's cab consisted only of Lunettes end walls with a small weather roof. The inflow pipes were led down at an angle outside the boiler to the valve boxes located below the smoke chamber. The safety valve was above the fire box. The two cylinders were in front of the barrel axis, the piston rods were not carried out to the front. The circulating sheet was located below the boiler and had wheel arches for the drive wheels.
The springs were arranged above the bearings. For reasons of space, the suspension had to be installed above the coupling axle using two small springs that were braced against each other (double ressort à pincette). The external engine took hold of the front drive axle. The internal control was a Stephenson type. On the boiler there was a sand dome , the downpipe of which led in front of the driving axis.
In the two-axle tender with an outer frame, the springs were located above the axle bearings. The spindle handbrake acted on the tender axles via four internal blocks. Between 1888 and 1890 the locomotives were equipped with a Wegner compressed air brake that acted on the tender axles. A vapor barrier was installed in front of it. It is unclear whether the locomotives all still received steam heating and speedometers between 1889 and 1890 - like the other B 2/3.
The name boards were on the side in the middle of the boiler. They were removed on the occasion of the new boiler. The numbers were only painted on when the JS was renumbered.

The locomotives were assigned to the workshop in Yverdon.
