just remember to alternate your common drop. if you drop a power feed every 10', do the following for the common or black wire. at 10' inside rail & power, at 20' outside rail & power, at 30' inside rail & power. you will have a better signal pickup for tmcc or dcs.
This depends on the make of track, lionels fastrack is manufactured with the common rails "tied" together so alternating is not necessary.
