Palatine P 3.I
Encyclopedia
The German steam locomotive
s of Palatine Class P 3.1 were operated by the Palatinate Railway
and were the first engines in Germany
with a 4-4-2
(Atlantic) wheel arrangement. The two-cylinder saturated steam locomotives with inside cylinders had in addition to an inside bar frame a characteristic outer frame for the rear part of the locomotive, that partly covered the driving wheels. The valve gear
was of the Joy
type.
In 1898 and 1899 Krauss
initially built eleven locomotives; in 1904 a twelfth followed that was equipped with a Pielock superheater
. Although the P 3s met their intended performance criteria, they were soon overtaxed by increasingly long trains.
The Palatinate Railway decided therefore on an unusual conversion: in 1913 the two-cylinder engine was converted into a four-cylinder compound engine by the addition of two outside cylinders, the inner ones becoming the high-pressure cylinders. However they did not achieve the higher performance required, just a lower fuel consumption of around 15%.
The Deutsche Reichsbahn
took over five of these locomotives as DRG Class 14.1 with numbers 14 101 to 14 105, but by 1926 they were retired from service. Also grouped into Class 14.1 were the Bavarian S 2/5
s.
The locomotives were equipped with tenders of the Bavarian Class 3 T 16.
Steam locomotive
A steam locomotive is a railway locomotive that produces its power through a steam engine. These locomotives are fueled by burning some combustible material, usually coal, wood or oil, to produce steam in a boiler, which drives the steam engine...

Joy Valve Gear
Joy valve gear is a type of locomotive valve gear, patented in 1870, where the movement is derived from a vertical link connected to the connecting rod. The vertical movement is translated into the horizontal movement required by the valve spindle by a die block moving in a slide which can be...

Superheater
A superheater is a device used to convert saturated steam or wet steam into dry steam used for power generation or processes. There are three types of superheaters namely: radiant, convection, and separately fired...
