Prussian P 4.2
The class P 4.2 locomotives were passenger locomotives of the Prussian State Railways , which were also used in express train services. They were a further development of the P 4.1 , from which they differed mainly in the composite design . There were two different versions.

The P 4.2 of the Erfurt design belonged to the test series from 1891 with four express and four passenger locomotives each, two of which were built in composite and two in twin design. Except for the changes necessary for the compound drive, it was structurally identical to the P 4.1 type Erfurt . As with this one, the running bogie didn't really prove itself here either. In addition, the locomotive had difficulties getting there, which were due to the otherwise more economical composite design. So it stayed with the two locomotives. They were first numbered hall 492 and 493, then hall 265 and 266 and from 1906 finally hall 1901 and 1902. They were retired by 1920.

The Prussian P 4.2 was a passenger locomotive type of the Prussian State Railways . After trials with the P 4.1 series with internal control and external control were not very convincing, there was hesitation in developing a P 4 in a composite design until the Union foundry from Königsberg developed the so-called Dultz's changing device . It was only through this that the access difficulties of the composite locomotives could be resolved. The P 4.2 was more powerful and more economical than the P 4.1 . A total of 707 copies were produced between 1898 and 1910, which largely corresponded to the vehicles of the S 3 series .
Other railways also had the P 4.2 in their portfolio.
- Grand Ducal Oldenburg State Railways : eight (see Oldenburg P 4.2 )
- Lübeck-Büchener Eisenbahn : five pieces with a shortened wheelbase
At the Deutsche Reichsbahn in 1923 , 549 locomotives as 36 003-540, 7101-7103, 7148, 7149 and 7163-7168 were planned for redrawing in their drawing plan for steam locomotives , in 1925 the 36 002-438 were still available. Most of the P 4.2 were taken out of service by the Second World War .
During the Second World War , the 36 441–443 from Lithuania and the 36 444–521 from Poland were part of the Deutsche Reichsbahn.
The Deutsche Reichsbahn in the GDR converted the 36 457 in 1950/51 to use coal-dust firing for experimental purposes . She received smoke deflectors and a rigid frame tender 4 T 30. It was retired in 1959 as the last P 4.2.
The vehicles were Tender senders equipped of types pr 3 T 12, T 15 and pr 3 pr 2'2 'T 16th
Used by the Mecklenburg Friedrich-Franz Railway
From the turn of the century, traffic on the route from Berlin to Warnemünde became increasingly important. In addition to pure "baths trains" also had coaches to Copenhagen to promote. The class P 3.1 locomotives used up to now reached their performance limits. A journey time of 112 minutes was planned for the section between Neustrelitz and Rostock. The choice therefore fell on the Prussian class P 4.2 locomotives. This had the necessary power and had sufficient reserves. Between 1903 and 1912, a total of 31 locomotives from Henschel, Humboldt and Linke were delivered and classified in class VII with the track numbers 201 to 231. The machines of the first delivery series (201 to 203) still had a type 3 T 12 tender. But for the second delivery series, the four-axle 2'2 'T 16 tender was also used and this was also exchanged for the first three locomotives.
From 1906 the locomotives were also used on the route between Lübeck and Strasburg and later even continuously to Stettin and Berlin. In 1913 the MFFE acquired the Prussian locomotive Posen 1915 (ex Posen 226) and assigned the train number 232.
1925 all locomotives in the DR numbers 36601-36620, 36651-662 redrawn . The retirement took place until 1931.
