- rwmj 4y agoThis one? https://www.railengineer.co.uk/slab-track-paving-the-p-way/ https://www.railengineer.co.uk/slab-track-paving-the-p-way/ How does this make the rails less likely to buckle? Just because it's held in place more tightly?
- pkulak 4y agoYes. They actually talk about it in the article.
- bitdivision 4y ago> The CWR is subject to compression loads due to temperature changes, which can cause buckling, or sharp lateral displacement. These phenomena are prevented using reinforced fastenings, sleepers and ballast. https://www.ejrcf.or.jp/jrtr/jrtr15/f38_tec.html https://www.ejrcf.or.jp/jrtr/jrtr15/f38_tec.html I found the above, but it doesn't say that much about buckling. I don't think they use slab tracks however. If buckling is the lateral movement of the track due to thermal expansion, I would imagine the old wooden sleepers would be much easier to pull sideways. Looking at the above link about slab tracks, they look far more secure and less likely to move sideways.
- gumby 4y agoI wasn’t familiar with rail ballast but found this good link which explains what the term refers to and how it helps keep the rails aligned (explicitly the posted article talks about when current mitigation is indequate). https://railroadrails.com/information/what-is-railway-ballast/ https://railroadrails.com/information/what-is-railway-ballas...
