DC wiring on shelf layouts
#3
Al:
If you use big enough wire, current loss isn't a problem.
My layout is about 16 feet square, around the walls, so I have track that is 50 feet (as the train runs) from a throttle.
I have 4 throttles and 3 block control panels - one on a side and 2 in the opposite corners. The big one controls a station that is about 16' long plus another 16' along the next wall.
My throttles are connected to the control panels with lamp cord -- the flexible stuff about 14 or 16 gauge from the hardware store.* There are 4 sets of it running around most of the layout. When I was building, I found that the store had 4 distinct colours/styles of this wire.
When I built the control panel I had some decent wire for connections, but I also had surplus telephone cable that I used to the track. I didn't do that on the later sections.


* this wire is generally handy to buy and reasonably priced. Just don't confuse it with the high voltage circuits.

In model railroading, there are between six and two hundred ways of performing a given task.
Most modellers can get two of them to work.
