The steam locomotive of the class 99.01, Pts 2/2 of the Pfalzbahn was a one-off and was manufactured by the Maffei company in Munich .
history
In 1916 the Royal Bavarian State Railroad procured a B-coupler from Maffei for their narrow-gauge lines on the left bank of the Rhine in the Vorderpfalz . When it was delivered, the locomotive was given a number of the Palatinate Railway (XXX) and the generic name Pts 2/2 . It was not until 1925 that the locomotive was given the number 99 011 when it was taken over by the Deutsche Reichsbahn and was listed as class B h2t . It was assigned to the Neustadt-Haardt BW and retired in 1931.
