The two tender steam locomotives that were acquired by the Sihltalbahn (SiTB) on the occasion of the opening of operations in 1892 were designated as E 2/2 .
The locomotives were also called "Gartehägli" locomotives because of the free-standing handrail around the boiler.
The locomotive was obtained from the Swiss Locomotive and Machine Works (SLM) in Winterthur.
history
The locomotives were purchased on the occasion of the opening of the Sihl Valley Railway to run passenger trains. The E 3/3 was procured as the third locomotive for freight transport and as support . Initially, it was even planned to purchase only ten-ton tramway locomotives for passenger trains, which could have carried a maximum of three two-axle cars. But they decided in favor of the more powerful variant and consequently bought these two E 2/2. This made it possible to carry at least four cars. But this variant also proved to be insufficiently efficient. They were well suited to cope with normal traffic and were also very economical to use. But when the weather was nice on Sundays, there was a lot of excursion traffic on the Sihltahlbahn. As a result, trains had to be long enough if you didn't want to run the trains twice. But precisely for that, these locomotives had no power reserves. That is why they only had four years of operation with the Sihltahlbahn and were replaced by another E 3/3.
Because the second E 3/3, which was purchased in 1893, was to be given the company number 2, the E 2/2 No. 2 was redesignated after just one year and was given the company number 4.
The locomotives could be sold to industrial railways for CHF 20,000 each. All this with an initial purchase price of 27,000 to 28,000 Swiss francs.
Technical
The two-axle tender steam locomotives were of the Brown type and had a double lever drive. This made it possible to install the cylinder and the control above the rotating plate, which meant that they were not as exposed to the road dust. The double lever drive acted on the second axis, while the first axis was designed as a coupling axis . The coupling rod was on the outside. The locomotives had an inner frame with an integrated water tank. There was a small and light external supplementary frame to accommodate the axis of the double lever drive, which also served to mount the cylinder. The springs were above the axle bearings. On the first axis below the cylinder between the two frames, on the second axis above the rotating sheet half in the driver's cab. To protect the staff, the handrail was not attached to the boiler, but free-standing outside the cylinder and the drive.
The cylinders had valve blocks below, which were controlled by a simple and easy handlebar control without an eccentric. The direction of travel was set and reversed using a lever control. The valve regulator, which was on the outside of the steam dome, was operated via a shaft and an eccentric.
On top of the boiler was the steam dome with a safety valve in the front and the sand dome with sandpit at the back . The steam supply lead outside the boiler to the valve boxes. There was only one sand pipe in front of the drive axis, which means that it could only be sanded properly when driving forward.
An automatic Westinghouse brake was installed. The air pump for this was located on the right front of the cab in the direction of travel. The coal box was on the left. Each wheel had a unidirectional brake pad.
Operational
The locomotives were intended to lead passenger trains and were then mainly used in front of passenger trains. But it quickly turned out that they were too weakly dimensioned. Because at that time a regular passenger train consisted of one baggage and two to three passenger cars, which meant that the performance limit of this two-axle locomotive had already been reached. Especially with regard to the planned extension of the Sihl Valley Railway from Sihlwald to Sihlbrugg, even longer and heavier trains had to be expected. Therefore, it was decided to sell the locomotives and buy more E 3/3.
Whereabouts
The number 2 (no. 4) was sold to the Thalwil dye works in 1896, where it was in use until 1937. Then it was scrapped.
The number 3 was sold to Von Roll Werke in 1887. First came to the Choindez plant, but moved to the Klus plant in 1912. In 1941 the locomotive was sold to Germany, where its track is lost.
