The NKAG 15 II locomotive was a five - axle meter - gauge tank locomotive that was built by the Jung Maschinenanstalt for the Nassauische Kleinbahn (NKAG). The locomotive was later taken over by the Brohltalbahn , was given the number III there and was in service until the end of 1966.

The NKAG already had a locomotive with the number 15 in 1914, which has survived on the Harz narrow-gauge railways as 99 6102 to this day.

history

Nassau Small Railway 15 II

The locomotive was procured for heavy roller carriage trains on gradients of up to 36 ‰, with a trailer load of 250 t. The locomotive was one of the largest meter gauge locomotives built in Germany . The long-time foreman of the Nassauische Kleinbahn contributed to the development. A favorable ratio of towing power and fuel consumption was expected from it.

The locomotive met these requirements. However, it was neglected to strengthen the superstructure for the use of the locomotive . Only the section Mudershausen - Zollhaus was prepared for use. There were several derailments on the remaining sections. The locomotive was parked in the cold for 866 days from 1952 to 1955. It was then decided to sell the locomotive.

Brohltalbahn III

The operating conditions on the Brohltalbahn were very good. The locomotive was given the number III and from 1957 onwards with the Brohl Valley Railway I managed the heavy freight train service on the route with gradients of up to 50 ‰ for almost ten years. Due to their high frictional load, these locomotives were better suited for the inclines than the Mallet locomotive II . The III was in service until the first diesel locomotives were acquired and was retired in September 1966. In 1967 the locomotive was scrapped.

Constructive features

The locomotive was a two-cylinder locomotive and equipped with a superheated steam boiler . The steam was superheated to temperatures of up to 300 ° C with a superheater. The boiler had a diameter of 1,300 mm and contained 70 heating pipes and 26 smoke pipes with internal superheaters.

During the construction, great importance was attached to a curve-going drive . The two outer axles could be moved sideways and lay in a Beugniot frame . In addition, the outer axles were provided with wheel flange lubrication . The middle axis was the only fixed axis. It had weakened wheel flanges . The locomotive was equipped with two sandboxes. From the beginning it was equipped with electric lighting, as a coupling it had a balancing lever coupling .
