Could this article please explain how TPWS works? It is linked to from Signal Passed At Danger, which (until I edited it), gave TPWS as the sole automatic method of stopping trains that pass danger signals. In Australia, we have what are known as "train trips" which do the same thing, and I very much doubt that these are the same as TPWS, but without an explanation of how TWPS works, I cannot be certain.

[edit] Northern Ireland?

considering the Northern Irish train network is entirely set up to Republic of Ireland standards, I believed that it used the same mix of CAWS and ATP that Irish Rail use, and not any other systems? All their trains are set up for CAWS/ATP, because many of them spend more time on Irish Rail track that on Translink track. --Kiand 18:11, 7 December 2006 (UTC)

Northern Ireland Railways are signalled in accordance with British, not Irish, signalling principles. Their railways have AWS and TPWS, but no CAWS. Signalhead 21:49, 3 January 2007 (UTC)

So how do NIRailways trains operate on the Irish network, and more importantly vice-versa? Irish Rail equipment does not have TPWS or AWS fitted, thats a definite. --62.77.181.1 14:31, 15 April 2007 (UTC)

Some NIR trains are fitted with CAWS, and some IÉ trains are fitted with TPWS & AWS. Signalhead 21:34, 21 April 2007 (UTC)
