Red light on GW-180 Transformer when hooked up to FasTrak

You have a short between the center rail and outside rails.  Start by dividing the layout in half and disconnecting half the layout by separating the track.  See if the problem follows one half, then divide that section in half and test again.

A close physical inspection of both sides of the track pieces is a good idea as well.

Remove the FasTrack coaxial terminal section with the little red indicator from the layout.

Hi John......followed your advice and found multiple issues.  2 tracks were missing center pins on one side, found 2 10" straights with no ground jumpers, along a couple of loose connections.  I ended up pulling every track apart, inspected and reassembled the whole layout.  It took all day but was well worth it. My Conrail switcher is running as we speak.  I can't thank you enough for the help and it came just in time.  My 3 granddaughters will be here tomorrow for the holidays and they'll be thrilled. 

Glad you got it going, but none of the things you found would cause a short.

I'm guessing something was shorting a track and was removed/dislodged during the investigation.  That's why I suggested the physical inspection.
