Oh my, the rail de-stressing/stressing horror stories I've heard. Rail snaps sideways and hits 2 guys right at the shin. Feet and ankles hanging on by a thread. blech....

The guy in the gif was not maintaining, he was obviously scrapping

What is and why stress, de-stress rail:

TL;DR
In hot weather rail expands. The extra rail kicks out sideways called a sun kink. Train goes in the ditch.

To prevent this, take a slice out of the rail and pull it together. https://www.youtube.com/watch?v=zlD2QAngBhs

Gets scary when they have to do a curve.

On really hot days, the run a hi-rail pickup truck in front of every train to spot sun kinks.

Rail anchors help prevent kinks




The really far out one was caused by an earthquake:
