When E 3/3 Nos. 3 and 4 are two Tender steam locomotives referred to the 1897 by the Sihltalbahn were purchased (SITB).
The locomotive was obtained from the Swiss Locomotive and Machine Works (SLM) in Winterthur. The sales price is stated at 38,300 Swiss francs.
They are derived from the E 3/3 delivered to the NOB from 1894 onwards .
history
The locomotives would be purchased with a view to extending the route from Sihlwald to Sihlbrugg. Because they did n't want to miss the connection to the Thalwil – Arth-Goldau railway line , which was opened as a Gotthard feeder in 1897.
Technical
The second axle was the drive gear set, while the first and third axles were designed as coupled gear sets. A normal long Walschaerts control was installed as a control. It had short drive rods and a reversing with a handwheel.
The steam dome with safety valve and the sand dome were located on the boiler. The two sand pipes only led in front of the drive axis and therefore only worked well when driving forward.
The leaf springs were arranged above the rotating plate and supported by the spring collar on the axle bearing via a rod. A balance lever was attached between the first and second springs.
A Westinghouse brake was installed as a compressed air brake; it worked both as an automatic brake for the entire train and, from 1912, as a regulating brake only on the locomotive. Four-block spindle brakes were installed, and the air brake also acted on the same brake blocks. The second and third axles were braked on one side. The air pump was attached to the side of the smoke chamber. It was replaced by a more powerful one in 1911. The air tank was attached under the driver's cab.
The locomotive whistle was on the driver's cab roof.
In the years 1898/99 a smoke burner from the Langer system was installed. At that time, a tire sprayer was also installed. The type of wheel flange lubrication helped to reduce wear.
Operational
The locomotives carried all types of trains up to electrification. After 1924 they were used as shunting locomotives. With the commissioning of the Em 3/3 No. 11 in 1962, the two locomotives were decommissioned.
Whereabouts
Both locomotives were not scrapped after they were scrapped, but instead installed as playground locomotives in 1965. No. 3 came to the Tannenbach playground in Horgen, where it was removed in 1988 and then scrapped. No. 4 came to Adliswil, where it was set up at the Werd schoolhouse. In 2015 it had to be removed for security reasons. After an external revision, it is now standing as a monument locomotive at Sihlwald station.
