Palatine Pts 3/3 H

The DRG Class 99.10, formerly the Palatine Class Pts 3/3 H of the Palatinate Railway, was a German narrow gauge steam locomotive. It was the superheated version of the PtS 3/3 N. Unlike the saturated steam version the upper section of these engines was no longer glazed, otherwise they were broadly identical. They could carry up to 2.0 m3 of water and 1.2 t of coal.
