Saxon X V
Encyclopedia
The Royal Saxon State Railways
designated four-coupled, Atlantic (4-4-2
) express locomotives as Class X
and the Deutsche Reichsbahn
subsequently grouped these locomotives into DRG Class 14.2 in 1925.
engineering works built the first two express locomotives of the new four-coupled, Atlantics with a four-cylinder compound engine. One of the locomotives was displayed at the Paris World Exhibition in 1900 and was awarded the Grand Prix
.
The Royal Saxon State Railways took over the two prize-winning locomotives and procured another 13 up to 1903 that differed from the prototypes, particularly in terms of the diameter of the carrying axles. They were the largest and most powerful locomotives in Saxony
to that point. The X V was employed on express train duties on the plains where its riding qualities and economy were impressive.
In 1920 the Deutsche Reichsbahn
took over all 15 engines and gave them the new numbers 14 201–215 in 1925. They were retired by 1926.
with a Belpaire firebox
, which was located between the frame sides. Two injectors provided the boiler feedwater.
The steam engine was designed as a de Glehn four-cylinder compound. The outer high-pressure cylinders drove the second coupled axle, whilst the inside low-pressure cylinders drove the first. The motion for the engine was a Walschaerts valve gear on the outer cylinders and a Joy valve gear
on the inner ones.
Braking for locomotive and train was provided by a Westinghouse
compressed-air brake. On the two prototypes the air pump was on the right, on the remaining locomotives it was installed on the left hand side.
The coupled axles were fixed to the frame. The leading bogie was an Erfurt design, the trailing axle was an Adams axle
