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.
