The class P 3.1 steam locomotives of the Palatinate Railway were the first machines with the 2'B1 '(Atlantic) wheel arrangement in Germany. The two-cylinder wet steam locomotives with internal cylinders had, in addition to the inner bar frame, a conspicuous outer frame in the rear part of the locomotive, which partially covered the drive wheels. The controls corresponded to the Joy design.
Krauss initially built eleven locomotives in 1898 and 1899; in 1904 a twelfth equipped with a Pielock superheater . Although the P 3 met the planned performance program, they were quickly overwhelmed by the increasingly longer trains.
The Pfalzbahn therefore decided to undertake an unusual conversion: in 1913 the two-cylinder engine was converted into a four-cylinder compound engine by adding two outer cylinders, with the existing inner cylinders becoming the high-pressure cylinders. This resulted not only in the desired higher output, but also in an approx. 15% lower fuel consumption.
The Deutsche Reichsbahn took over five of these locomotives as class 14.1 with the numbers 14 101 to 14 105, but they were retired in 1926. The Bavarian S 2/5 was also classified in the 14.1 series .
The locomotives were equipped with type bay 3 T 16 tenders .
