feeder lines

Hi

David

 I had done my layout and used 12 gauge for feed wite and 14 gauge wire for drops

 The layout is 25+50 we have never had anty problem with the tmcc or the legacy system. we did have problems with the mth dcs and still working them out. 

Star wiring is a techniques used with DCS.  You can use this for TMCC/Legacy and you definitely want to do this is you intend to ever use DCS.  They call it "star" wiring as the feeds are run in pairs.  DCS uses the center rail for carrying the command signal and paired power feeds (i.e. both pieces of wire are the same length) keeps signal propogation issues to a minimum.  TMCC can use "bus" wiring as the power and command signals are completely isolated.

Since I legacy I guess I will run a buss line and see if it resolves these issues. Will a 14 Awg buss work with 16 Awg drops or is it better to use the 12 Awg? I have 14awg.

Unless you need more amps 14 should be fine.  What type of track.  The more "sections" the more drops you will need.  If you are using short pieces of sectional track you may want to wire jumpers between the sections to supplement the main feed/drops.  Most of the issues with power loss are at the pins where sections of track are joined.  If there is enough corrosion or oxidation or the pins aren't tight you will get erratic power distribution..

I use Fastrack, 072.
