I sure do thank everyone for their input.
I ran some of my enigens one at a time to see how much current they draw. approx. one amp each. I find that if I run fewer trains I am ok. and better if I run a passenger set on track three and not on track one. I still may have a wiring problem. I will check all my home runs again.I am using AWG12 copper wire. could the switches between loops be an issue? I am using both ross and atlas switches and switch power is from an independant supply. thanks.Ed.
