The locomotives of Class XIX of the Grand Duchy of Mecklenburg Friedrich-Franz Railway were deployed on the Bad Doberan–Heiligendamm narrow-gauge.
The locomotive was given the number 1003 by the Mecklenburg State Railway and was incorporated into Class XIX.
To handle the higher levels of traffic, three similar engines were ordered from Henschel.
The horizontally arranged two-cylinder, wet steam drive acted on the rearmost coupled axle.
The two front coupled axles had leaf spring blocks at the height of the running plate.
