The P 3 2 series of the Oldenburg State Railways comprised seven two-axle passenger steam locomotives , which Hanomag supplied from 1894 on the basis of the G 1 developed by Hartmann in Chemnitz . They were the first composite locomotives for passenger train service in Oldenburg and were still very similar to the B couplers with simple steam expansion.
Constructive features
Instead of a steam dome , they had steam manifolds with regulators in the smoke chamber. The locomotive's air brake only acted on the drive axle. The Allan control was designed with slot suspension and a special mounting of the rocker arm and slide lever in order to meet the requirements of the compound engine.
Although all seven locomotives of this series were still intended to be changed to 33 7001 to 33 7007 in the preliminary re-drawing plan from 1923, they were retired by 1925 and are no longer listed in the final re-drawing plan.
