Gleiskörpern

Gleiskörpern is a German term that translates to "track bed" or "track structure" in English. It refers to the entire supporting structure upon which railway tracks are laid. This structure is crucial for the safe and stable operation of trains, ensuring that the tracks maintain their alignment and load-bearing capacity.

The primary components of a Gleiskörpern typically include ballast, sub-ballast, and the formation layer. Ballast, usually composed of crushed stone or gravel, is the uppermost layer and serves to distribute the load from the sleepers (or ties) to the layers below. It also provides drainage and allows for adjustments to track geometry. Beneath the ballast lies the sub-ballast, a layer of coarser material that further enhances drainage and prevents the finer particles of the formation layer from migrating into the ballast. The formation layer, also known as the roadbed or embankment, is the natural or engineered ground on which the entire track structure is built. It must be stable and well-compacted to support the immense dynamic forces exerted by passing trains.

The design and construction of a Gleiskörpern are vital considerations in railway engineering. Factors such as soil type, climate, expected traffic loads, and intended train speeds all influence the specific materials and dimensions used. A well-constructed Gleiskörpern minimizes track degradation, reduces maintenance requirements, and contributes to a smoother and safer ride for passengers and freight.
