The Hg VII TK was a double-coupled narrow-gauge tender locomotive of the Royal Saxon State Railways .
history
The locomotive was delivered in 1873 by the Erfurt company Maschinenfabrik Christian Hagans with the serial number 1 to the Oberschlesische Zweigbahn in Beuthen . In 1882 the Kgl. Saxon State Railways bought the locomotive and gave it track number 5. In order to be able to use it on the Saxon network, the locomotive was re-gauged from 785 mm to 750 mm. The machine was mostly used as a construction and auxiliary locomotive when building the narrow-gauge railway lines . In 1891 it was still in use with a mileage of 3,100 kilometers on the Oschatz – Mügeln – Döbeln and Mügeln – Nerchau routes . With the sufficient supply of locomotives of the classes IK and IV K , the locomotive became more and more dispensable and from 1892 onwards it was increasingly rare to find it in service. It last ran in 1895 on the Wilkau – Wilzschhaus and Mosel – Ortmannsdorf routes . In 1897 the locomotive was sold.
Constructive features
The locomotive had a sheet metal inner frame that also served as a water tank. The steam boiler was of the Crampton type. The boiler water was fed through two injectors. The regulator attachment was on the front long boiler. The steam lines to the cylinders were led outside of the boiler.
The two-cylinder wet steam engine was external. The drive took place on the rear wheelset. The Allan controls were also external.
The wheel sets were rigidly mounted and supported on the frame by individual overhead springs. The locomotive had a crank-operated spindle brake that acted on the wheels of the driving axle. In 1886 it was converted to a throw lever brake . The machine had a reel for the lever brake .
The coal supply was stored in side containers in front of the driver's cab. The sandpit was in front of the coal box on the circuit. The driver's cab was only provided with a simple protective roof.
