DCC wiring

[cacole]

There's not much need to do a quarter test on a layout that is running okay on DC block control when you switch to DCC, because nothing in the wiring is being changed.  The quarter test proves nothing except that your DCC system's internal circuit breaker is functioning properly.  If there was a problem with the wiring, trains would't have run properly on DC block control, either.

I would do as suggested, and then do the "quarter test".  Turn the DCC system on, and place a quarter across the rails at various places around the layout.  If the system detects the short, and shuts down, your wiring is sufficient.  If not, you'll have to beef it up a bit.

When I switched to DCC, I figured I needed a larger feed to all the layout. I wish now that I had done just what Jeffery suggested. With all your blocks on switchs that can be turned off,  finding a bad short or problem can easily be traced to one block. Sure saves a lot of time!

 Just disconnect your DC supply and connect the DCC system. Turn all your blocks on. That's it.

My layout currently uses blocks in order to operate 2 trains at the same time on the same track. I am switching to a DCC system. What wiring is needed to accomplish this task? Do I need to wire just one section of track or at various sections?
