The steam locomotives of the Palatinate class P 2.I were express locomotives of the Palatinate Railways with the wheel arrangement 1'B1 '.
In this type of locomotive, the running and driving axles were connected to a Krauss-Helmholtz bogie by means of a forked drawbar . The rear barrel axis was in an outer frame. The locomotive was able to pull a 106-ton train on the plain at 90 km / h. The vehicles were equipped with type 3 T 12 and 3 T 14 tenders . From 1891 to 1896 Krauss built a total of 22 locomotives of this type, 13 more went to the neighboring Hessian Ludwigsbahn and later joined the Prussian State Railways as P 3 .
The twenty copies taken over from the Reichsbahn were to be given the numbers 35 7001 to 35 7020 as class 35.70 , but were retired before they were redesignated. The locomotives had names, including QUEEN MARIE and v. BUT .
The QUEEN MARIE (Krauss 2421, built in 1891) came in 1922 to the Railway Museum , where most of the long boiler and the underlying frame with two driving axles removed and the remainder was prepared as a cutaway model. The model (without tender) was in the Nuremberg repair shop until 1957 . It was then set up on the grounds of the Technical University of Karlsruhe , today's Campus South . It is protected as a cultural monument.
