The Swiss Nordostbahn ( NOB ) procured 1867-1895 34 Schlepptender steam engines of the type C 3/3 which were supplied by three different manufacturers.
Manufacturer
The first six machines were purchased from StEG in Vienna in 1867 , the purchase price was quoted at 53,400 Swiss francs.
The next 24 machines came from the Esslingen machine factory and were delivered in three series between 1873 and 1876 (6 machines in 1873, 8 machines in 1875, 10 machines in 1876). The purchase price was between 76,000 and 83,300 Swiss francs.
The last four machines were manufactured in 1889 by the Swiss Locomotive and Machine Factory (SLM) in Winterthur, the unit price was 47,500 Swiss francs.
The successor to this locomotive was the NOB D 3/3 .
Technical
The locomotives of the Bourbonnais type were purchased for freight train service, but with a top speed of 55 km / h they were also suitable for transporting mixed trains. The wheelbase was 3270 mm and all axles were in front of the firebox. The boiler was designed as a long boiler , so that there was an overhang of around 2000 mm to the front and around 2500 mm to the rear. The boiler did not have a steam dome, but a steam collecting pipe over the entire length of the boiler. The boiler was 1950 mm above the top of the rail. In the first six machines, it was made of sheet steel, which was far too inelastic, so that the boiler had to be replaced as early as 1872/1873. These replacement boilers and the new boilers for the Esslingen machines were designed according to the Maey design without anchors and with a sloping smoke chamber tube wall. These also failed and had to be replaced from 1888.
The Ramsbottom safety valve was on the manhole cover above the fire box. The rotary valve regulator was located in the smoke chamber and was operated by a vertical lever on the rear wall of the boiler. The drive was mounted in a 30 mm thick inner frame with lots of cross bracing. The suspension consisted of four longitudinal springs connected with longitudinal levers above the bearings of the first and second axles, as well as an inverted transverse spring resting on the bearings of the third axle. Because the external engine acted on the second axle, it was moved 175 mm towards the rear axle in order to achieve a better rod length. The control was designed in the Allan type, the first with full eccentrics, the others with eccentric cranks and pocket linkage. The reversal took place with screw and wheel. The piston rods were not originally carried out, which was changed after the boiler replacement on the machines from Esslingen and SLM.
The machines were the first of the NOB to have a railing around the boiler and a front wall door in the driver's cab. There was no counter-pressure brake installed. The sandpit was between the frame. The tender was equipped with an 8-block spindle brake. The Westinghouse brake installed from 1893 onwards also acted on these brake pads . The tender was a typical NOB tender with a long wheelbase. From 1894 the machines were retrofitted with a device for steam heating and a speedometer of the Klose type .

Notes on the table:
a According to the list from 1875, the numbers 137–142 were provided.
b Were placed at the beginning of the numbering on the occasion of the renumbering in 1895, and then also placed in this order at the SBB .
c Numbers 145–148 had been rented to the Zurich-Zug-Lucerne Railway in 1880 and then sold; they kept the same numbers there. When the railway was taken over by the NOB in 1892, the locomotives were returned to the NOB's portfolio.
d Sale to the Austro-Hungarian Army Administration , 1918 to MÁV while retaining the SBB numbers.
Operational
The machines were assigned to District III at SBB ; the maintenance was carried out by the Zurich workshop and partly by Rorschach.
