The class XIX locomotives of the Grand Ducal Mecklenburg Friedrich-Franz Railway were used on the narrow-gauge line Bad Doberan – Heiligendamm . The triple-coupled machines were given the class designation T 7 from 1910 onwards. In 1911 they were transferred to the Neubukower Rübenbahn .
history
The locomotives of type XVIII were soon no longer able to cope with the increasing volume of traffic. A triple-coupled machine was therefore ordered from Krauss in Munich. The locomotive was given the number 1003 on the Mecklenburg State Railroad and was classified in class XIX. Another locomotive followed in 1898 and was classified as number 1004. In 1910 the railway line was extended to Arendsee. To secure the higher traffic, three similar locomotives were ordered from Henschel . With the commissioning of these locomotives, which were also classified as T 7 , the two Krauss locomotives were handed over to the Neubukower Rübenbahn. The locomotives were still listed in the preliminary re-drawing plan of the Deutsche Reichsbahn from 1923. But they were retired by 1924.
Constructive features
The locomotives had an internal frame that was designed as a water box. The long boiler consisted of two shots. The steam dome with the safety valve sat on the front shot. The smoke chamber was kept very short. The chimney had a cob spark arrester. A Prüsmann chimney was later used.
The horizontally arranged two-cylinder wet steam engine worked on the rear coupling axle. The Stephenson control with crossed eccentric bars was also on the outside.
The two front coupling axles had sets of leaf springs at the same height as the circumference. These were connected by compensating levers. The rear axle was cushioned by a transverse leaf spring package.
The handbrake acted on the two outer sets of wheels from the outside. The locomotives were later fitted with a Knorr air brake. The sand spreader sat in the middle of the boiler and sanded the outer wheel sets from the outside. Initially, the engine was covered. The locomotives also had a steam heating system, a steam flare and De Limon central lubrication.
