The Krupp "Knapsack" is a standard gauge, three-axle saturated steam tank locomotive ( wheel arrangement C) from the post-war type of program locomotive and waggon Krupp , Essen . Their design is based on a single piece, which was delivered to the "AG for nitrogen fertilizers" in Hürth-Knapsack as early as 1935 . The type designation is also derived from this forerunner.
With an output of around 400 PSi and a permissible top speed of 45 km / h, primarily designed for use in the transfer and shunting service of industrial and works railways , twelve locomotives of this type were delivered to eight different operators in Germany from 1949 to 1961 . Another three copies were exported to Turkey in 1953 and 1960. The most important operating location of Knapsack was the Niederberg colliery in Neukirchen-Vluyn , where up to five machines were temporarily used.
Preserved copies
Six copies of the Knapsack have been preserved in Germany to this day. The last machine built, delivered to the Niederberg colliery in 1961 under the serial number 3435, was also the last of its type to be operational; until 2016 it was regularly used to cover the museum train of the Hespertalbahn in Essen-Kupferdreh .
