In 1870, the Swiss Northeastern Railway ( NOB ) acquired six C 2/2 type C 2/2 locomotives with a tender from the Schwartzkopff machine factory in Berlin .
backgrounds
As the network expanded, the need for locomotives in passenger train service grew, so between 1870 and 1876 the NOB acquired a total of 49 type C 2/2 steam locomotives , these were supplied by three machine factories. Since the NOB also had a large number of two-axle tank locomotives, it had procured most of the main-line locomotives with the B wheel arrangement in Europe. In France, for example, this wheel arrangement was banned for fast-moving locomotives after an accident on the Versailles Railway, as a broken axle led to a serious accident. In general, this design is decried as a rail eater.
Technical
The copper firebox was made in the Maey style. The one-piece, vertically corrugated, 13 mm thick copper sheet was bent in a semicircle and had no ceiling anchor. The stud bolts were located in the wave troughs of the vertical side wall. Eight liftable, non-tensioned anchors were available for emergencies. The panes of the fire door were made in two parts. The boiler did not have a steam dome , but a collecting pipe. The rotary valve regulator with the inlet pipes was built into the smoke chamber and was operated with an operating lever on the rear wall of the boiler. Two Ramsbottom safety valves were mounted on the manhole cover .
The inner frame was 15 mm thick. The front axle was supported by two springs above the frame. The rear axle on an inverted transverse spring, the center of which was mounted in a cross frame, while the ends were supported on supports on the axle bearings. An auxiliary water tank with a capacity of 1.6 m³ was arranged between the frame.
The external engine acts on the rear axle. The locomotives had a simple external Allen control with an eccentric crank and pocket link. Initially, the piston rods were not passed through to the front, but this was done later, and the piston rods passed through to the front were covered with a protective sleeve.
They were coupled to a two-axle tender with a long wheelbase. This had an outer frame.
The machines only had a spindle handbrake that acted on the tender axes and could be operated on the stoker side. They never got a steam heater built in.
