LOL. Yeah, there's nothing quite like watching a high-cube
covered hopper full of plastic pellets rocking down some bad
track. I recall a couple of times we went back and looked,
and could see where a wheel had dropped down on the ties for
a bit, until it got to a good tie that held gauge and it
re-railed itself.

So when it got hot in the summer and you had to
replace a rail, you had to swing a mall against the web to get it to
pop out of place. On especially hot days the gap made by popping a
rail out would shorten as much as two inches.

Today with CWR it's normal to try and install it on the hottest
days, so that when the rail cools it'll be in tension. That
causes fewer problems.
