This is rather vague. Derailing seems serious, although I understand that e.g. killing a freight train driver is less bad than a collision with a passenger train. How bad is such a derailment?--Patrick 13:22, 14 December 2005 (UTC)
I tried to clarify it, please check.--Patrick 13:46, 14 December 2005 (UTC)
- Note that a freight train driver is more likely to obey a signal than a runaway wagon or freight car. Dysprosia 01:25, 15 December 2005 (UTC)
"It causes an accident to protect the line ahead at all costs, for example, if there are passenger trains on the segment of line ahead of the catch point." does not seem a better formulation, it could be read as "it causes an accident if there are passenger trains ahead", which is not what is meant.--Patrick 23:21, 15 December 2005 (UTC)
Is a catch point only used on lines with no passsenger traffic? Or only used on lines with little passsenger traffic? Intended for runaway wagons only or also for manned freight trains?--Patrick 23:25, 15 December 2005 (UTC)
- I've removed the example, since it's basically presented in the paragraph below. Catch points are used on passenger lines as well, as far as I recall. I don't know about the specifics of use though. Dysprosia 05:57, 16 December 2005 (UTC)
[edit] Trap Points v. Catch Points
This article, as it currently stands, confuses 'trap points' and 'catch points'. This is the explanation that I have added under "Points (Rail)".
Depending on the situation in which they are used, run-off points are referred to either as 'trap points' or 'catch points'. Trap points are provided at the exit from a siding or where a goods line joins a line that may be used by passenger trains. Catch points (now obsolescent) were installed on the running line itself, where the railway climbs at a steep gradient. These points are a throwback to the days of the 'unfitted' goods train, their purpose being to derail the rear portion of a train that had become divided, so as to prevent collision with a following train. Catch points were usually held in the 'derail' position by a spring.
- I've posted a question at Wikipedia talk:WikiProject Trains#Catch points and trap points about the difference between trap and catch points, with the hope of clearing up the differences (whether one definition is incorrect, or there is some difference in terminology) and making this article agree with the information at Railroad switch#Run-off points. If anyone feels they can help in this regard, it'd be great if you could reply at the link above! →Ollie (talk • contribs) 20:56, 17 December 2006 (UTC)
[edit] Changes
I've made some major improved to this pages today, I hope they are generally liked. I hope I haven't made the article too British, both in spelling and content. If editors want to globalise it a bit more that would be good.
I'm going to file a requested move from Catch point to Catch points (currently a redirect here), as my sources say that the plural is the correct term, at least in the UK. This would also bring the title into agreement with the article lead.
Any improvements are of course gladly welcomed. →Ollie (talk • contribs) 22:31, 18 February 2007 (UTC)
