BTW, the inner rail you see here just right of the left rail is a dilitation rail - it makes sure that if a train derails, it won't fly out of the curve.

That's weird. In North America, the tracks over every train bridge have these extra rails, but I've yet to see them on a curve.

In the UK, I think it's called a 'Check Rail'. Different name, same purpose - to prevent derailment on tight track curves (or over bridges).
There's a lot of Check Rails on this particular line, as it was originally built to narrow gauge standard and the curves are pretty tight for standard gauge trains.

They're in all places where the risk of derailment or the possible damage involved with a derailment is particulary big. Here the problem would be a train hitting the bridge, in my local town there is a building built over the tracks - there they have check rails as well because in the very unlikely event a train would derail, it would hit the pillars and bring the building down with it.
Similarly, all rail tunnels in the Netherlands are built as "slides", each track in it's separate gutter with as less objects in it as possible. In the event of a derailment, a train will just slide on and not crash onimpact with something.

The Slide idea is a good one.

I used to work on a section in the mountains of Britsh Columbia where freight derailments were not highly unusual. It is really surprising how much that inside rail can do to avert disaster. One time a car got off the track and the train simply pulled it for a few miles before they stopped , It was a lot of overtime for us replacing tyes but the domino effect that could have put most of the train over was averted.

Actually, I bogused on my first comment, it's indeed a check rail. A dilitation rail doesn't exist. A dilitation joint is a joint to allow for expansion of the tracks (near bridges etc)

I like the picture-the composition between the rusting rails and the flowering bushes.
