Cover agency

from Wikipedia, the free encyclopedia

A cover point (abbreviation: Dkst ) is an operating point of the free line on the German railways , which ensures rail operations on movable bridges , level crossings of railroads, looped tracks and construction sites . The functions of another operating center can be transferred to a cover center at the same time, e.g. B. that of a block point, branch point or junction.

The named danger spots are usually protected with main signals . Main signals of a cover point that is not at the same time a block point or branch point are not integrated into the section block ; they are then called cover signals . In practice, there were or are coverage signals in front of combined rail / road bridges and dangerous level crossings.

Movable railway bridges on the open route are almost exclusively secured by cover points.

In the case of overlap points with older signaling technology, a main form signal is set up on both sides of the bridge, in simple circumstances it can also be a signal Sh 2 (old designation: cover disk Ve 1). Examples: Lindaunis bascule bridge with form main signals, Sanderbusch swing bridge with cover plates; meanwhile both replaced by Ks signals as block and cover signals.

In the case of movable bridges on double-track lines, there was a form main signal on the standard track and the cover disc on the left (formerly also: wrong) track . Example: Itzehoe bascule bridge until 1983, Friedrichstadt swing bridge until 1988.

At the Deutsche Reichsbahn in the GDR , cover panes in front of movable bridges were dismantled almost everywhere in the 1960s, only two pairs of signals remained until the post-reunification period.

At cover points with newer signaling technology, a main light signal is set up on both sides of the bridge; it can be supplemented by a light blocking signal. Example: Weener bascule bridge ( Friesenbrücke ).

Most movable railway bridges are located within train stations / docks. They are secured by main light signals ( Kattwykbrücke Hamburg), light blocking signals ( Mannheim, Oldenburg, Emden, Lübeck etc.), track blockers (Harburg), in the area of ​​the former Reichsbahn by shunting stop signals (waiting signs Ra 11b, Anklam) or by cover panes ( Elisabethfehn ). Special designs are occasionally used for light signals.
