In 1875, the United Swiss Railways procured two type C 2/2 passenger steam locomotives . At first they had the series designation II, from 1887 to 1902 they were designated as B2T.
These locomotives were purchased from the Krauss & Cie locomotive factory in Munich, and the purchase price per locomotive was 52,000 Swiss francs.
Technical
Since they were built together with a series for the Saalebahn in Germany and are identical to this, it was probably a bargain purchase.
The machine with a wheel base of 3000 mm had an inner frame. The boiler position was 2075 mm above the top of the rail. The fire box was above the rear axle. The boiler was provided with 196 boiler tubes, 3200 mm long. The steam dome was located on the rear half of the boiler and thus differed from all other VSB locomotives. The Klose safety valve was on the steam dome and the regulator in the smoke chamber. An auxiliary water tank was integrated in the inner frame according to the Krauss design. The rear axle was provided with two suspension springs suspended under the axle bearings, while the front axle was equipped with a transverse spring. A three-point suspension was thus achieved. The engine grabbed the rear axle with a convenient rod length. The control was an all control, which was still equipped with a full eccentric. The lever reversal worked via an upper control shaft. A Klose speedometer was tested on these machines for the first time in 1879 and retained after the tests were completed. There was also a steam heater.
The two-axle tender had an inner frame. It was to be provided with a four-block external brake (hand brake) and a vapor barrier of the Klose type. In 1892 an automatic Westinghouse brake was installed in place of the vapor barrier. There was no drive wheel brake.
Operational
You were assigned to the Rorschach workshop and thus also to SBB District IV.
They could carry 200-300 tons on a level track.
