The Mecklenburg Class P 4.2, formerly Class VII, were early German steam locomotives operated by the Grand Duchy of Mecklenburg Friedrich-Franz Railway and were used specifically for hauling express trains on the line from Warnemünde to Berlin. They were mechanically identical with the Prussian P 4.2. All 31 units were taken over by the Deutsche Reichsbahn who incorporated them as Class 36.6 with numbers 36 602–620 and 651–662. The first series of numbers were engines with a 14 t axle load, the second those with a 15 t axle load. In 1931 the last locomotive of this class was retired.
No. 36 601 was a Prussian P 4.2 that was redeployed to Mecklenburg in 1920.
Apart from three units, these engines were equipped with Class 2'2' T 16 tenders.
