More PM using the 3rd throttle.
I like having the bulbs as backups to the CB's as they provide a quick reference that there is a short, plus the throttle's CB doesn't 'pop'.
I think I've figured out how to easily break the DCC mainline into blocks without actually doing it. If a short occurs, I'll just turn off the existing DC block toggles that the DCC routes through until the short is eliminated. I see no easy way to easily break up the mainline into DCC blocks and still have the option to also switch to DC without adding a lot of extra toggles.
