QUOTE: Originally posted by cornmaze A local branch in my area has a good number of mud-pumping joints. Ballast is a mix of gravel, crushed rock, pea gravel, and mud. For the past 20 years that I've noticed, the railroad dumps new ballast between the rails after tie change-outs. Then machines come in to groom the ballast. After all is said and done, the new ballast is shoved off onto the shoulders of the track where it doesn't seem to do anything, and the muddy, pumping joints remain as before. (?!!) I don't get it.

QUOTE: Originally posted by cornmaze Can anyone explain to me why a soft or uneven track will cause a derailment? There was a derailment not long ago in my area due to track being rough (crews reported a bumpy ride in that spot). So what is going here? Do wheels actually lift off the railhead in these bad track areas? I guess they'd have to... but it's hard for me to imagine such a heavy thing as a railcar getting airborne on the track. Any insights on this? Thanks.
