Just thought I'd chime in here about the discussion in regards to railroad track. Not that I am an 'expert' (meaning an old has-been
drip-under-pressure), I do run trains on them on a daily basis.
Sun kinks, or thermal expansions as the 'experts' call them, are a fairly common occurance any time the temperature exceeds 90-100 deg F. I see them
every summer, some large enough to displace several hundred feet of rail, most only displace 10 feet or less. It is a very uncomfortable feeling to go
over one, believe me!
