Hands up…You in the back there?
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.
No plans to model it.
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.
Pete
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.
