The German steam locomotive of Palatine Class Pts 2/2 of the Palatinate Railway was a one-off and was built by the firm of Maffei in Munich. Notable features were the high boiler and the locomotive frame used as a water tank. Coal was carried in two bunkers on the left and right of the driver's cab.

After the formation of the Deutsche Reichsbahn the engine was taken over and given the number '99 011'. It was retired by 1931.
