DOTRT (down on the rail trail): what is it?

Sorry for the crap pics, my curiosity didn’t warrant an actual stop in my ride! Anyways, I rolled past a junkyard / shop that had a couple neat hulks slowly rusting away and saw this interestingly proportioned tarp. Maybe a 60s Renault or something of that era? Definitely quirky!

Also nabbed this pic of a poor beetle.

And finally, here’s a shot of some rusty tubes with some purple painted tubes in front of them!
