Absolute block

Surely AB is absolute block, while what is being described here is Track Circuit Block, —Preceding unsigned comment added by 81.156.84.94 (talk) 09:02, 20 September 2008 (UTC)

Those are British terms. This article isn't relevant to British practice. –Signalhead ^< T > 12:39, 21 September 2008 (UTC)

Perhaps it should say so to avoid confusion. Where in Wikipedia can one find an article on Track Circuit Block? Chevin (talk) 15:53, 21 September 2008 (UTC)

Good question. Whilst TCB is unlikely to justify an article of its own, it does come within the scope of the safeworking article (which uses the Australian term but claims to cover railways worldwide). At present, the article only seems to deal with methods of single line control, however. –Signalhead ^< T > 16:31, 21 September 2008 (UTC)

What makes it worse is that in the UK the acronym ABS stands for Absolute Block System - quite a different way of working Chevin (talk) 08:32, 13 May 2009 (UTC)

Lead Sentence

The lead sentence as it stands now is confusing: "Automatic Block Signaling, or ABS, is a block system that consists of a series of signals that divide a railway line into a series of blocks and then function control the movement of trains between them through automatic signals." It seems that it should read "...series of blocks and then functions to control the movement..." If there is no correction or objection in a few days, I will change it myself.
