The Mecklenburg Class G 3 was an early German steam locomotive operated by the Grand Duchy of Mecklenburg Friedrich-Franz Railway.
In total, there were eight G 3 locomotives in the Mecklenburg fleet, which all built between 1887 and 1895.
Of these two originally came from the Lloyd Railway, Neustrelitz - Warnemünde.
The engines had a steam brake and an outside valve gear of the Allan type.
Five engines were intended for transfer to the Deutsche Reichsbahn, to be numbered 53 7201 to 53 7205; however they were withdrawn before the renumbering plan was implemented.
