Block position
Block Set (abbreviation Bk ) or block items are railway installations , which in its function as Zugfolgestelle define a Zugfolgeabschnitt. The associated company buildings are sometimes referred to as log cabins . Block sections usually have one block signal for each direction of travel and track. They are mainly found where the distance between two train stations is so great that the desired minimum headway time cannot be achieved. In the past, the main reason for setting up block sections was that communication between the train sequence points was not possible over long distances. In the early years of the railway, all train sequence stations therefore had eye contact with one another and communicated via optical signals.
There are block units locally manned by block guards and automatic block units (Sbk) that function completely automatically without the involvement of an operator and use a track vacancy detection system for train detection .
Blocking points for trains guided by displays ( LZB or ETCS Level 2 in SR mode ) can also be limited by block identifiers instead of conventional shape or light main signals . This includes the LZB block identifier (no signal in the sense of the EBO ) and the ETCS stop board ( Ne 14 ).
A block point can be designed as a junction , a junction , a train station , a cover point , a stop , a stop and a transfer point .
