Gus, Thanks for the site. I'll check it out.

Len, That makes sense. I'll give that a shot and see what happens. Thanks for your help.

Len, Thanks in advance for any info you can give me. I operate a NCE system with handheld cab. My power is run through 1 booster and power pack that plugs into 1 outlet. I have 8 buss lines all run into 2 Digitrax PM42s for a total of 8 blocks. The switch machines are hooked up to each buss line for the block that operates that portion of track. I control the switch machines with the cab so when I turn the system on, the track power and the switch machines are on the same power. Let me know if you need any more info.

I have 2 reverse loops and a wye on my layout. There are times when I power up the track that the tortoise switch machines switch on their own. This only happens occasionally. Any ideas why this happens? Both the reverse loops and the wye have reverse modules to each section of track and each section is on it's own block. Don't know how to correct the problem. Very frustrating!!
