Palatine P 5

The locomotives of the class P of 5 Pfalzbahn were six-coupled tank engines.

You should replace the high- and moderate traction is no longer sufficient two -coupled vehicles Pfalzbahn, especially the Palatinate P2II. In view of the short Palatine routes with their frequent gripping and turning operations only a tank locomotive into consideration, but in which to improve performance, particularly for the acceleration of firings, a cauldron, and three driving axles came were required. Furthermore, the stocks of coal and water should be sized very large, so that a high coverage could be achieved without Nachbunkern; but at the same time should the consumption caused entering while driving decrease in inventories friction mass does not change significantly.

For these claims, the disposition of a trailing bogie under the cab and tender, which propped up the majority of the mass of the related inventories. To reach the front, a good leader of the locomotive on curved track, was built instead of a run, for example as salmon bites gantry axis is a Krauss- Helmholtz bogie. In regard to the desired wheel base of the machine, the drive shaft must be disposed immediately before the first coupling axis. As a steering rack from the barrel axis and first coupled axle due to short drawbar was not possible by this arrangement, Richard von Helmholtz made ​​the steering rack from the propagation axis and the second Kuppelradsatz from. Due to the structural Pickup the barrel axis immediately before the first Kuppelradsatz and side clearance of the axes of the bissel further had to be arranged unusually high and with an inclination of 1:10,5 above the barrel axis, the cylinder of the steam engine, also could drive only on the third Kuppelradsatz done.

In addition, since the cab was quite long, but 440 mm narrower than the water tanks, a unusual appearance of the locomotives was.

The company Krauss delivered from 1908 twelve specimens that were stationed among others in Kaiserslautern, Ludwigshafen, Homburg and Bingerbrück. The German Reichsbahn took over all vehicles and equipped them to hot steam machine. After the end of World War II were still nine copies left. Most of these were sold to private railways. The last locomotive owned by the German Federal Railroad in 1951 scrapped.

After they had had good experiences with the Palatine P 5, the Palatinate Railway decided to purchase additional copies of this type in a stronger version. Thus, the Palatine Pt 3/6 was produced from 1911. A total of 19 vehicles were purchased. From this two-cylinder steam engine in 1923 a further 10 vehicles for Bavaria acquired as Bavarian Pt 3/6. These were used on the express track between Garmisch -Partenkirchen and Munich. From the Reichsbahn all vehicles were taken, with the Bavarian printer vehicles operating numbers were 77110-119. During World War II, a machine was lost. The German Federal Railroad took over 27 vehicles that were retired by 1954. A locomotive remained at Deutsche Reichsbahn in 1956 and retired.

The Naßdampflokomotiven the series could carry a 140 -ton train on a grade of 20 per thousand at 30 km / h in the plane, the hot steam engines, however, under the same conditions 180 t.
