I was just unplugging it....I'll try disconnecting the power supply completely. Cheers

Are there any locos sitting on the track duirng your VOM test? They'll most likely read as a short.

Other than that, you may be reading something in the DCC unit itself. Try disconnecting that from the rails/buss and see what you read. Also, is anything else connected to the track or buss? Electronic stuff?

Anyway, try to isolate any loads that are connected across the track.

There are a couple things that did not occur to me last night that I could have checked. Yes, I have two locos sitting on the track right now, and they were there last night when I used my VOM to test for isolation. It also never occured to me that I should disconnect the Power Cab and then test for continuity. I have a nice collection of electronic tidbits (decoders for the Torts, Hex Frog Juicer board...) wired to the track buss too, however it did actually occur to me that these little gems even when powered off could allow a meter to sense continuity in the rails.

I'll try that and see what reading it give me. Interesting stuff to learn and know about for future reference that's for sure.

Thanks for the ideas and suggestions guys! Thumbsup
