I have an HO layout, and I will build an N layout soon.
My question is when I go DCC, can I use the same command station for both layouts, with a booster for each, and different adresses for the locos?
Yes you can. Just adjust each boosters to the voltage level for each scale and make sure you label them. If you keep the loco number seperate you won’t have a problem. If the two layouts are going to share the same benchwork, it’s a good idea to use different colors for the N and HO bus wires.
