I have a 4x8 layout with ZW transformer and quite a few working Lionel accessories. Rather than home run all the common wires from my accessories back to the ZW (or a buss bar), I've used a short lead with a spade connector under the nearest outside rail or O gauge track. This all seems to work fine, but now I'm concerned that I may be "overloading" the common if that's possible?
Any concerns about doing this?
