A tender steam locomotive that was purchased by the Sihl Valley Railway (SiTB) in 1899 is called E 3/3 or now Ed 3/3 No. 5 .
The locomotive was obtained from the Swiss Locomotive and Machine Works (SLM) in Winterthur. The sales price is given as 45,700 Swiss francs.
Like the E 3/3 No. 3 + 4, it is derived from the E 3/3 supplied to the NOB from 1894 , but already corresponded to a modernized version with smoke burner and wheel flange lubrication. The boiler dimensions were also slightly different from those of the two locomotives delivered 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-length Walschaerts control was installed as a control. It had short drive rods and 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 an air brake. It worked both as an automatic brake for the entire train and 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 1965 and 1972 an overhaul was carried out in the repair shop of the Deutsche Bundesbahn in Offenburg . On the outward journey the locomotive was loaded onto roller bolsters, on the return journey it drove on its own wheels. During his stay in 1965, it was given a new coat of paint based on the ideas of the engineer E. Fontanellaz.
commitment
The locomotive was to be found before all types of trains until electrification. From 1924 it was mainly used as a shunting locomotive . When the Em 3/3 (identical to the SBB version) was delivered in August 1952 , it also lost this task. But as early as July 1952, the first public steam special trips took place, for which the No. 5 was kept. This special train was marketed as "Schnaaggi-Schaaggi" (slow Jacob). As a result of boiler damage, it had to be drawn in 1988 and the privately owned Ed 3/3 "Muni" (former BASF works locomotive, used by SOB No. 102) took over the management of the "Schnaaggi-Schaaggi" until 1996 the contract expired. In the meantime it was decided to make the Ed 3/3 No. 5 ready to drive again so that the «Schnaaggi-Schaaggi» could be continued. Since the Sihl Valley-Zurich-Uetliberg-Bahn (SZU) could not bear these costs itself, the Zurich Museum Railroad Association (ZMB) was founded, to which the locomotive was subsequently transferred. The locomotive was refurbished and has been running again since 1997. Since then, it has been running special trains in the summer months as "Schnaaggi-Schaaggi".
Since the locomotive is used as a mainline locomotive, it was given the official designation Ed 3/3. Although it was never employed by SBB , it was also given a unique vehicle number ( 90 85 0008 565-3) that fits into the SBB steam locomotive system . Their relationship with the E 3/3 ( 8551-8559 ) taken over by the SBB from the NOB is now also documented.
