The tender steam locomotive , which was purchased by the Sihl Valley Railway (SiTB) in 1912, is designated as E 3/3 No. 6 .

Like the E 3/3 No. 3 and 4 and E 3/3 No. 5 , it is derived from the E 3/3 shunting locomotives delivered to the NOB from 1894 onwards, but unlike the older machines, it is a superheated steam locomotive with one Superheater.

The locomotive was purchased from the Swiss Locomotive and Machine Works (SLM) in Winterthur and cost 41,000 Swiss francs, making it significantly cheaper than the E 3/3 No. 5, which in 1899 still cost 45,700 Swiss francs.

Technical

The locomotive was the only SiTB locomotive to have piston valves with internal flow. The control took place via an eccentric placed on the counter crank of the drive axle.

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 revolving 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 as a regulating brake only on the locomotive. There were 4- block spindle brakes installed. The second and third axles were braked on one side. The air pump was attached to the side of the smoke chamber , the air tank under the driver's cab .

The locomotive whistle was on the cab roof.

Operational and whereabouts

Before electrification, the locomotive was found in front of all types of trains. After that she was practically unemployed. Since it was considered sufficient to keep No. 3-5 as a shunting locomotive, No. 6 was sold to the Uerikon-Bauma-Bahn in 1926. After they were hired, she came to the Basel gasworks in 1948, where she replaced her former Sihltalbahn colleague - the E 3/3 No. 1. It was also given company number 1, and its predecessor, built in 1892, was scrapped in the same year. No. 6 met the same fate in 1956.
