In absolute block working, a block section (or simply section) is a section of railway line between one signal box and another – in the typical absolute block, lines are paired, with an up – towards London (or in Scotland, Edinburgh) – and a down line in the opposite direction.
The modern-day system mostly uses two, three, and four aspect colour-light signals using track circuit – or axle counter – block signalling. [1] [2] It is a development of the original absolute block signalling that is still being used on many secondary lines. The use of lineside signals in Britain is restricted to railways with a maximum ...
Automatic block signaling (ABS), spelled automatic block signalling or called track circuit block (TCB [1]) in the UK, is a railroad communications system that consists of a series of signals that divide a railway line into a series of sections, called blocks. The system controls the movement of trains between the blocks using automatic signals.
Signalling block systems enable the safe and efficient operation of railways by preventing collisions between trains. The basic principle is that a track is broken up into a series of sections or "blocks". Only one train may occupy a block at a time, [citation needed] and the blocks are sized to allow a train to stop within them. [1]

Russian Railways uses Electric Token Block on some lines, most notably the Yanisyarvi – Lodeynoe Pole railway. The electric staff instruments manufactured by Webb and Thompson shown in the picture above are in use on the Buenos Aires (Constitución Station) to Mar del Plata line (Ferrocarril Roca) in Argentina, as of 2019.
