The train station Körle Ost is a depot of the high-speed line Hanover-Würzburg in the area of ​​the North Hessian community Körle . It is 16 kilometers south of Kassel-Wilhelmshöhe and 73 kilometers north of Fulda .

Location and structure

The station is the first overtaking station on the route south of Kassel and is located around one kilometer east of the municipality of Körle. The location of the station is bounded by viaducts to the north and south. In between, 1,646 m were available for the development of the station. In addition to the two continuous main tracks, two passing tracks, a siding track and a few short sidings . In addition, a signal box and a substation were located on the site.

The system is essentially formed by a 1100 m long and up to 27 m deep cut . The width of the cut at track level is 15 to 37 m. Other parts of the system are on dams . The crown width reaches up to 120 m.

history

planning

The arrangement of overtaking stations in the Hessian low mountain range turned out to be difficult, as the maximum longitudinal inclination of these stations had to be limited to 1.5 per thousand and these had to be in a straight line at least in the area of ​​the switch connections. In the section between Kassel and Fulda, based on the length of the section, the proportion of engineering structures was particularly high at 70 percent (56 percent tunnels and 14 percent bridges).

The structure was in planning section 13 of the middle section of the new line.

construction

Construction began in October 1984.

In the deeper area of ​​the facility, layers of the middle red sandstone were removed in the course of the construction work .

The slope inclination was set at 1: 1.5 along the entire new line in the course of the design planning. A flattening based on the actual geotechnical conditions was hardly possible in the construction-accompanying implementation planning . In the Körle overtaking station, complex slope stabilization with prestressing anchors and shear dowels should initially be dispensed with. As a result, there was a local landslide , as a result of which extensive safety measures were taken.

Due to the lack of strength, part of the embankment was stabilized with anchors over a length of around 500 m in the eastern area of ​​the system. In the autumn and winter of 1984 tests were carried out to prove the load-bearing capacity of these anchors. A total of 900 anchors 16 to 24 meters in length were installed to ensure stability.

The excavated volume is around 1.3 million cubic meters. 1.1 million m³ of this was installed in the Stellberg landfill located around 5 km east of the station . The remaining 200,000 m³ were installed in the route area. The excavation of 10,000 to 12,000 m³ per day was removed by up to 45 trucks at an interval of up to 30 seconds. In order to withstand the resulting loads, forest roads were expanded over a length of around 10 km.

The estimated construction costs (status: approx. 1986) amounted to around 20 million German marks (around 10 million euros ).
