A **block post** in [railway signalling](/source/Railway_signalling) is the [signal box](/source/Signal_box) at one end of a [block section](/source/Block_section).[1]

## German practice

In Germany, block posts are known as *Blockstellen* (abbreviation: *Bk*) and are defined as railway facilities on the open line that mark the end of a block section, as part of a block system. They usually have a [home signal](/source/Home_signal) in each direction and on each running line. They are mainly found where the distance between two railway stations is greater than average.

In the early years of the railway, block posts were local signal boxes staffed with block post keepers. Today there are only a few of these classic, railway staff-operated block posts. Their function has been largely superseded by equipment that forms part of an [automatic block signalling](/source/Automatic_block_signalling) (*Selbsttätiger Streckenblock* or *Sbk*) system or by a central block post in a station signal box at one end of the section between two stations.

Block posts are described in the German railway regulations, the *[Eisenbahn-Bau- und Betriebsordnung](/source/Eisenbahn-Bau-_und_Betriebsordnung)* or *EBO*, at § 4 sub-paragraph 4.[2]
