Thank you for the responses. I was going to use phone wire for the switch drop to the bus. Since you mentioned small amount of electric and one switch at a time I guess bus line can be same gauge. The additional lighting would be a few track side buildings.
The reason for seperate wiring comes from Lionel wiring guide explaining switches work best and longer if 14 volts is supplied. Lionel also points out that the bulbs won't overheat at 14 volts. I know nothing about amp draw, wire gauge, ect. I appreciate your help very much.
