The United Swiss Railways (VSB) and their predecessor railways purchased a total of 22 passenger train steam locomotives of the type Eb 2/5 . At first they had the series designation II, from 1887 to 1902 they were called A2E.
The first 20 examples of these tank locomotives based on the Engerth system were procured from Maschinenfabrik Esslingen between 1857 and 1858 , and two locomotives were replicated by VSB in 1895. Numbers 21–32 were ordered by the Südostbahn , numbers 33–40 by the United Swiss Railways . The purchase price of the Esslingen locomotives was around 75,000 Swiss francs.
Technical
The inner frame of the Engerth locomotive, which carried the engine and the boiler , was articulated in the area of the fire box with a three-axle support tender . The outer frame tender, designed as a running axle bogie, carried the main load of the fire box and could not be separated because otherwise the machine would have tipped backwards. In contrast to other Engerth locomotives, these locomotives had the water tank mounted on the tender. This had the advantage that the adhesion weight was independent of the water supply and the boiler weight could be increased. So it was possible to reach a speed of 75 km / h without a leading running axle.
The boiler with 138 boiler tubes with a length of 4450 mm was 2010 mm above the top of the rail. The engine was located between the frame and was equipped with a control according to the Gooch system. This was operated with a lever and an upper control shaft. The piston rods were not carried forward. The sandboxes for each wheel were individually attached to the outside of the box and were operated together by wire pulls. There were two feed water pumps . On the right side there was a drive pump driven by the coupling pin of the driving axle, on the left on the water tank there was a piston steam pump.
The spindle brake was initially designed in four blocks and acted on the two rear tender wheels, later it was expanded to six blocks.
modification
In addition to the installation of a new tank for 10 bar - later with the third tank even 12 bar - the machines were fundamentally renewed, so that a new appearance resulted. In addition, the frame was replaced by a plate frame, which was extended beyond the first tender axis so that the locomotive could now be supported on the tender between the 1st and 2nd tender axes via a transverse spring. The locomotive was lengthened by 340 mm during the conversion. The total weight increased by 4 tons as a result of the conversion, whereby only 2 tons counted as the adhesion weight. The third boiler increased the original weight by 7.4 tons; here, too, the adhesive weight only increased by 5.5 tons.
In 1879, the first locomotives were given a Klose- type speedometer , which was initially placed in front of the driver's cab next to the long boiler. In 1883, the locomotives began to be equipped with the Klose steam spring brake , which could also be used as steam heating . From 1902 a four-block drive wheel brake was installed, which only acted on the drive axle.
In the last years of service, the maximum speed was reduced from 75 km / h to 65 km / h forwards and 60 km / h backwards.
The SBB assigned numbers according to the age of the boiler and not according to the previous VSB numbering. All machines were canceled.

Operational
The locomotive series was assigned to the Rorschach workshop and thus also to SBB District IV.

Remarks
- ↑ a b The two locomotives No. 21 and 22 were parked in 1877 and officially decommissioned in 1881. Two new machines were built from their components and spare parts in 1895.
- ↑ When the St. Gallisch-Appenzellische Eisenbahn (SGAE) was merged with the Südostbahn, the locomotive name "Helvetia" was duplicated.
- ↑ a b On the occasion of the merger of the SGAE and the Südostbahn, the Latin locomotive names were replaced by German ones.
