Wiring Blocks Common Rail or Isolate both rails?

steve <snorring@...>

I have a layout with blocked sections. I isolated both rails in each
section. I am using DCC and will be installing a BD4 to operate
signals through an SRC24.

Do i need to open 1 rail and make it common through the entire layout,
or can i leave both rails isolated? I have all my power comming
through a 4 block circuit breaker.

Thanks for your help.
