For things that are "hmmm".
Rule 1: All post titles except for meta posts should be just plain "hmmm" and nothing else, no emotes, no capitalisation, no extending it to "hmmmm" etc.

You already found the answer but I was going to comment that the pic was a joke.. a train wouldn't even notice those things on the track.
They do have derailers that are designed to specifically pop a train off the tracks though. They are made of steel and are usually put on the end of secondary lines just before they meet a normal line. In the event that if a train car rolls away it ensures that it can't roll into an active line and cause an accident but will instead get derailed and popped off the tracks.
