Welcome to the forum.  Trains.com has a garden railway forum, which may know more about your issue.

Most of us are HO or N scale and T & K section and 1015 are gobbledegook to us.  In our world, in DCC, there are reversing modules which would handle a reverse loop.  In DC it can be done with DPDT switches.

Not up on G scale, so I'm not sure what a K section is.  The 1015T is an insulating section, though.  Do you have another way of powering the reverse loop?

Do you have a voltmeter, to check voltage in that section?

What you're dealing with reverse loops is basically a short circuit. Since you're able to enter the loop with no issues, I'm assuming that you have the loops insulated at both ends of your layout. What you need is to be able to reverse the polarity of the track outside of the loops, because the trains are trying to go in the opposite of the section you entered the loops. I use DPDT switches for each section; the common track and the two loops. Get yourself a copy of "Easy Model Railroad Wiring" by the late Andy Sperandeo from the Kalmbach bookstore.

It's a long story, but I recently inherited ALOT of G scale trains and thought it would be nice to add a small loop in the garden. That loop has qickly turned into a large layout with a reverse loop at each end. I finally got the track set and leveled so I figured I'd give it a test run, and had problems with both loops.

When the loco enters the loop and crosses the 1015T section it dies, as if there is no power. This happens at both loops. I was worried that maybe they were old or damaged, so I repalced one with a brand new one and it didn't work either. I tried flipping the T section just incase, but nothing. The K section has the arrow pointing out of the loop, towards the switch as indicated in the instructions.

Is there something that I'm missing, or an easy diagnostic? If it matters, I'm using a cheap Playmobile loco now, since the track is still in construction mode and I didn't want to bring out the good stuff quite yet. I have LGB locos to use if it matters. 

THANKS YOU!!
