We call them glad hands here. But it looks like the same thing as palm couplings.

Also fun fact while I think of it, iirc Edison had a business partner called Westinghouse and it was him who I believe designed the first air brakes for locomotives
It worked so well, they were adopted into road freight worldwide
So when you see wabco, which is a very common trademark, it stands for westinghouse anti braking system
