After a 25 year hiatus I am setting up my trains again. It looks to me like the SW U posts are each independent - that is they are not linked to a common bus. So, when I wire the layout I have to run hot and ground wires for both controls. Is that correct?

Olsen's kindly hosts the service documents for the SW which indicate the U posts are internally connected (Click to expand):
