The locomotives of Class XIX of the Grand Duchy of Mecklenburg Friedrich-Franz Railway were deployed on the Bad Doberan–Heiligendamm narrow-gauge. The triple-coupled engines were classified as T 7 locomotives in 1910. In 1911 they were transferred to the

Neubukow Beet Railway Neubukow (literally "New Bukov", where 'Bukov' is a Polabian adjective from " beech tree") is a town in the Rostock district, in Mecklenburg-Western Pomerania, Germany. It is situated 18 km southwest of Bad Doberan, and 21 km northe ...

History

The Class XVIII locomotives were soon unable to cope with the increase in traffic. As a result, a triple-coupled engine was ordered from Krauss in Munich. The locomotive was given the number 1003 by the Mecklenburg State Railway and was incorporated into Class XIX. In 1898 another locomotive, number 1004, followed. In 1910 the line was extended as far as Arendsee. To handle the higher levels of traffic, three similar engines were ordered from Henschel. With the introduction into service of these locomotives, that were grouped into Class T 7, the two Krauss locomotives were given to the Neubukow Beet Railway. The engines were still listed in the first Deutsche Reichsbahn renumbering plan in 1923, but they were retired by 1924.

The sanding gear sat on the middle of the boiler and sanded the outer sets of wheels from the outside. To begin with the running gear was covered. The locomotives also had steam heating, a steam bell and a De Limon centralized lubricating system.
