As a genus of the designated Royal Saxon State Railways two tank engines of the type Meyer .
history
For operation along the winding Erzgebirgsnebenstrecken developed Saxon machine factory in Chemnitz in 1890 a bogie locomotive of type-Günther Meyer . However, only two locomotives with the serial numbers 1658 and 1659 were built . The two locomotives were given the track numbers 822 and 823 and the names RASCHAU and CROTTENDORF .
Initially they were classified in the genus H M I TV . From 1896 they were then called M I TV ; from 1900 referred to as I TV .
The locomotives did not prove themselves, so that initially no further locomotives of this type were procured. The locomotives tended to run unevenly, especially at higher speeds. In addition, there was an increased tendency to skid when starting up. Similar locomotives were procured from 1892 for the Saxon narrow-gauge railways as class IV K.
It was not until after the turn of the century for at Dresden located Windbergbahn powerful and particularly curve-going locomotives were needed, it came to the construction of similar locomotives. However, these differed significantly from the original design (cf. Sächsische I TV ).
The M I TV was withdrawn from service in 1922, and the Deutsche Reichsbahn gave them no new numbers.
technical features
The locomotives had a long boiler made from two sections. The standing kettle was designed with a semicircular ceiling of the Crampton design. Two non- suction Friedmann injectors were used to feed the boiler .
The steam engine was designed as a four-cylinder compound drive with Heusinger control and flat slide valves. The smaller high-pressure cylinders were on the rear, the larger low-pressure cylinders on the front bogie. The bogies were connected by a coupling iron in order to reduce any counter-rotating movements.
The water supply was housed in containers on the side, the coal in a box behind the driver's cab.
The locomotives originally only had a vapor barrier as braking equipment, supplemented by a throw lever brake. Westinghouse air brakes were later retrofitted.
As special equipment, the locomotives were equipped with a Latowski type steam flare.
