Talk:Derailment

message: In the article, flangeless wheel is linked to blind driver which in turn redirects to driving wheel.  The end result is you click on flangeless wheel and end up at an article which says nothing about what a flangeless wheel is, which is very confusing.  I don't know enough about the topic to figure out the best way to fix it.  -- RoySmith (talk) 04:14, 9 January 2007 (UTC)

replies: text: Track caused derailments are usually caused by wide gauge. Proper gauge, the distance between rails, is 56.5 inches. As tracks wear from train traffic the rails tend to spread apart. This is primarily because wood ties weaken and crack from the stress of bearing train load tonnage. As ties weaken they loose a solid tight grip on the spikes which hold the track gauge. As the gauge between rails widens, the train wheels drop between the rails.Train tracks most often loose gauge in curves, where the outside wheels push the rail out.  Most railroads are replacing wood ties with concrete ties.  Concrete ties are better as they are prestessed and poured with a metal slot to hold the base of the rail in place. But converting existing tracks to concrete ties is costly and time consuming.

The width of the tread of a standard gauge wheel is about 3 inches (don't quote me!) so the rails have to go only a small amount wide, before you have trouble.
Concrete ties have much longer life than wooden ones, even though they cost more.  Good timber sleepers are also hard to come by as forests are denuded.  It therefore makes sense to change to concrete sleepers when the timber sleepers are life expired.  Remember that is costs to change sleepers in addition to the cost of the sleepers themselves.

thread_title:  Reverse curves? 

message: The text is locale-specific in a couple of places, such as saying that "Proper gauge ... is 56.5 inches ... on standard gauge track", "Each rail segment is 39 feet long", and "The wheel rests on an area of rail no larger than a dime in size".  This needs to be corrected. Teemu Leisti (talk) 03:27, 12 September 2009 (UTC)

message: It would be interesting to know what was done in case of derailment, how locomotives were rerailed again in the early times of railroading in the 19th century. Did they already have available adequate devices as cranes or similar? --Ingo64 (talk) 10:14, 3 June 2011 (UTC)
thread_title:  Rerailment 

message: The first paragraph of this section Methods_to_detect_rail_breaks needs to be clarified or eliminated.  A "clean break" (head, web, and foot) is most unlikely and connecting "pins" to the head would not eliminate other conductive pathways.  By the way, for transit properties a "clean" break would not be detectable because of the traction power return cables along the trackway.  My recommendations would be [a] to give emphasis to prediction of rail breakages and [b] to expand the "See also" entry with a link to a more comprehensive treatment at Rail_inspection#NDT_methods.

thread_title:  Methods to derail a train 

message: Practically all of this article is of a dubious technical standard and is written in the style of an enthusiastic amateur. There is plenty of half-truth and true-but-irrelevant material, and it badly needs someone with access to verifiable sources (unfortunately not me) to do something about it.Afterbrunel (talk) 17:58, 2 October 2012 (UTC)
thread_title:  Dubious and non-authoritative 

message: I have now deleted the previously written "example accidents". These were simply cut-and-paste from the article Lists of rail accidents and did not seem to illustrate any of the issues in this article.
I have added a few that (I believe) are illustrative; mine are all UK based so far; some more are needed, worldwide. Could I urge that any that are added are based on official factual reports ... newspaper reports and sensational "popular" books tend to be fanciful and focus on frivolous and lurid detail -- "bystanders looked on horrified as the packed express train plunged to its doom in the torrent hundreds of feet below" ... 
I'll be doing more on this article but as always, anyone is most welcome to help. Afterbrunel (talk) 11:22, 26 June 2013 (UTC)
thread_title:  Example accidents 

message: Hey guys and girls, I will be planning on doing a major redesign and cleanup of the article because it contains some weasel paragraphs that can go off topic. I have found one section "General Introduction" that goes completely off topic, and I removed the section because of this. But there is more of the article to fix, I consider globalising the article so that is refers to the global perception of "derailment". Have any questions, no problem, leave them here below!
