The steam locomotives of Baden Class IV c were passenger locomotives operated by Grand Duchy of Baden State Railway in the former south German state of Baden.
History
As part of the procurement of 2-4-0 locomotives in the early 1870s, a total of eight batches of Class IV c engines were ordered. These locomotives were used above all on lines with steep inclines in the Black Forest and the Odenwald. As a result several engines were equipped with a Riggenbach counter-pressure brake.
Design features
Then dimensions of these engines were largely the same as those of the Class IV b. However the double frame was dropped and replaced by a simple plate frame. The engine had a very short wheelbase and as a result good curve-running performance. In addition the carrying axle had a side play of 10 mm. It was returned to its centre position by sloping bearing surfaces (geneigte Doppelflächen). The grate area of the firebox turned out to be very small; as a result its steam generation was not particularly satisfactory. Trials with ribbed tubes did not produce any improvements. The large steam dome sat on the rear boiler section.
The outside wet-steam engine had inside valves and drove the first coupled axle. The wheels were sprung with leaf springs located over the top, that were linked by a compensating lever between the coupled wheels.
The vehicles were equipped with tenders of classes 2 T 8 or 2 T 6.67. Several locomotives were equipped with rearward-facing driver's cabs on tenders. This enabled them to work routes without a turntable.
