The class CV steam locomotives of the Bavarian State Railroad were one of the first European express locomotives with a 2'C wheel arrangement.
history
Maffei built a locomotive for the Bavarian State Exhibition in 1896 at his own expense. With coupling wheels 1,640 mm in diameter, it was designed as a multi-purpose locomotive. After the exhibition, the Bavarian State Railroad bought this locomotive and stationed it in the Munich workshop . After extensive tests, she ordered additional locomotives, but in a reinforced design and with a coupling wheel diameter of 1,870 mm, i.e. as pure express train locomotives. Maffei delivered 42 copies between 1899 and 1901.
The CV had a four-cylinder compound engine of the de Glehn type , with the low-pressure cylinders acting on the second coupling axle on the outside - arranged between the bogie and the first coupling axle - and the high-pressure cylinders acting on the first coupling axle on the inside. The locomotives did not yet have a superheater. With a maximum trailer load of 160 t at top speed, the CV could only be used in heavy express train service for a few years. As early as 1903, the locomotives migrated to subordinate services, but were able to hold on there for a long time.
17 machines had to be handed over to France after the First World War. The Deutsche Reichsbahn took over 22 units as class 17.3 with the numbers 17 301 to 17 322. They were retired by 1930.
The vehicles were a Tender respondents to type bay 2'2 'T 21.5 equipped.
