Hi Bob if my assumption is correct, ( Atlas customline T.O.) then DCC would be the way to go for my layout, it would certainly reduce the throttle requirement to the command station and one hand held, or maybe even one of them Zephyrs would fill the bill, then I'd be able to forget about power routing.
It is my intention in the future when I have enough 630's built, to run double headers ( long hood coupled to long hood ). If the encoders in each were programed to the same address, would this work, or would seperate addresses be required because one loco is actually running in reverse?In DCC there is a unit called a Reverser
