I currently have 1 TMCC and 1 Legacy and 1 Vision Line Legacy on 3 separate loops, all loops are connected to the same Legacy control unit and one Lionel 180 brick transformer.
Currently a second level is being built to run the VL Bigboy and I plan to have a separate 180 brick to power it, plans are to add another Legacy engine in the future so the top track will have 2 legacy engines, the loop is about 46 feet long.
Please, I am an simple unskilled model train operator and no electrical experience.
THE QUESTION:
With that in mind and in my words, can I splice the white wire and connect it to the upper level or just add a second wire, if a second wire is better, what gauge wire .
Thanks
Brent
