Wiring my new layout

Are you running conventional or command?  If you happen to be considering DCS, you may want to wire differently.

For two loops, I'd probably put two drops on each loop, one on each side of the loop.  You don't need a bus going around under the track.

John right now I am running conventional. However I will eventually get into DCS and Legacy locomotives. I want to wire everything up and make sure I have enough power before I move onto the next step of my layout.

This is what my current track plan looks like... I plan on adding some o36 switches for industrys in the coming weeks. 

You'd probably get away with just connecting up to a couple of drops, this is small enough that most of the signal issues probably wouldn't occur.

Here's what I'd probably consider, planning for the future.

Wire the power to a central location under the table to a terminal block.  Then run individual drops to the spots indicated.  For DCS, the star wiring is recommended, that's what this is.  Next, for DCS you'd want the center rail broken at the break spots indicated.  The two breaks at the switches separate the two loops so you can run conventional separately on each loop.  I'm assuming two power feeds for conventional or command on this print.

Thanks again John. I plan on buying the MTH 100watt power brick to power each loop. I have old lionel transformers for the switches and accessories. My plans were to come out of the 100 watt transformer and plug that into the TIU. From the TIU I will run power wires to the MTH 24 port terminal block. From there I will run power drops with lionels power track wires to the terminal. The only thing I am not sure of is how to put "breaks" into my layout. Do they sell some sort of adapter for lionel fastrack to isolate the rails? How do I go about with doing "breaks".

The 1 3/8" track piece has a jumper that puts breaks in if you remove the jumper.  Also, you can unlimber your trusty Dremel Tool with a cutoff-wheel and make your own break if necessary.

Ah ok. I have a few of them so I will disconnect the wire instead of cutting the center rail. Thanks for the tip John.
