In 1892 and 1897, the United Swiss Railways procured a total of seven mixed- train steam locomotives with a type C 3/3 tender, which the VSB listed as type B3T. The four machines from 1892 were obtained from the Saxon machine works in Chemnitz, the three machines from 1897 from the Swiss locomotive works in Winterthur. The purchase price is stated as 68,000 Swiss francs.
Technical
It is a long boiler type. This means that all axes are in front of the fire box. The driving force was directed to the central axle. In order to achieve a cheaper rod length, the middle axis has been moved towards the rear axis. The locomotives had an inner frame, the boiler position was 1920 mm above the top of the rails. The frame was reinforced on the machines of the SLM. The suspension springs suspended under the axles were connected to those of the second and third axles with longitudinal levers (compensation levers). The boiler with its 184 boiler tubes 4400 mm long carried a steam dome in which the slide regulators were installed. The safety valve was housed in a panel above the fire box. The coupling between the engine and the tender consisted of a large transverse leaf spring, on the end of which two small shock buffers pressed. The external engine was provided with a Walschaerts control with a straight backdrop according to Helmholtz. The reversal took place via a screw and wheel with an upper control shaft. The piston rods were carried forward. The tender is a two-axle tender with an outer frame of the NOB type. Thanks to this design, the water tank could be installed between the frame. The tender is equipped with an eight- block external brake (hand brake). The automatic Westinghouse brake also worked on these blocks. The cylinder for this was arranged upright at the height of the driver's cab. The automatic brake also worked on four brake blocks on the locomotive. These were located between the first and second axes and, controlled by toggle levers, also acted on them. The sandpit was located between the frame and was controlled with compressed air. Steam heating and a speedometer from Klose were installed.

Operational
You were assigned to the Rorschach workshop and thus also to SBB District IV.
They could carry 900 t on a level track and 185 t at 20 per thousand.
