Feed the loop track on both sides of the switch. Probably you have a power routing switch there and when it is set for the spur track it cuts off power to the loop beyond the frog. Just run another set of feeders from your reversing unit to the loop beyond the frog. Observe the proper polarity of the feeders
Can you provide us with a track diagram? That would make it easier to visualize your problem.
If you can post a diagram, show us where you have gapped the rails.
Also, if it is a reverse loop, what are you using to reverse polarities? Are you using an auto-reverse unit or a toggle switch?
Are the Peco switches Insulfrog or Electrofrog?
Look forward to more information.

Peco makes two kinds of turnouts, insulfrog and electrofrog. If you have insulfrog turnouts, the track which is not selected will not have power applied to both rails, only the one for which the turnout is set. Depending on your feeders to the track , you may be depending on the turnout to route power, which it will not do in some configurations.

Hi,Pabdo
I may be reading this wrong, but I think you have a reversing loop which has both ends into a single turnout. Is that right?
If your spur comes off the reversing loop and doesn't connect to any other tracks, you don't need gaps at the spur turnout, just power the spur from the reversing loop track power bus. The reversing loop bus should be powered from the output connections of an auto-reverse circuit. I like the PSX-AR, as it is all solid-state -- no mechanical relays -- and it switches silently and FAST.
You do need both rails gapped between the turnout and both routes into the loop. Also make sure the frog has reliable power to it with the points thrown both ways.

this is probably a common problem but I cannot seem to find the 'fix'. using dcc, the loop has a spur coming off which is powered properly. when the switch is thrown the power is lost between the gapped junction at the beginning of the loop and the switch. yes, there is still power to the spur which is gapped. I 'am using peco switches and this switch is not causing a short. can I assume that one of the rail joiners on the outside rail is not transmitting power? thanks for your help. pabdo
