Hands up......You in the back there?

"All of the world's problems are the result of the difference between how we think and how the world works."
I've heard them refered to as a Breather Switch, but not commonly in North America. Maybe a recent term.
Your photo almost looks like harper's Ferry, WV? Amtrak had a bad derailment on the former B&O in Kensington, MD in 2002, due to a sun kink.

No that I recall on a railroad.
The only expansion joints that I know of is on cruise ships.
Amtrak America, 1971-Present.
Okay, Who Models Expansion Joints Like This On Their Layout?
No plans to model it.
Rio Grande. The Action Road - Focus 1977-1983
I haven't modeled this in the past and don't plan to.
But it would be a nice detail to add.

I'm sorry but that looks more like a derail. Breather switch would be on both rails and not have a throw bar. There must be something behind the photographer that needs protection from runaways or inattentive crews.

Sorry but I take that back. It is an expansion section. Had to look again. My eyes are as old as me and my medication sometimes messes with them.
Well, I must admit that is a new one for me. I wonder how far back this design goes?
I model 1954.............
Sheldon
Never heard of it. The only expansion joints I know about is used in concrete construction.

Nope. Mainline at Magnolia WV. The pictures turned up on the B&O historical society the other day. The throw is to bend the rail into place if the track circuit breaks.
