Re: Detecting DC vs DCC track power
The "one DC locomotive" limitation on a DCC system is not a Digitrax limitation, it is a limitation inherent in the scheme used to enable it. What you are effectively doing with (asymmetrical)

Re: Detecting DC vs DCC track power
That¡¯s why you need to put the circuit on _both_ rails. That ensures a complete path for both supplies. Right. This is that same idea, moved up to shutting off a section of rail. You could also add

Re: Inconsistent behaviour with the dispatcher
Block tracking neither knows about nor cares about trains. Its responsibly is to transfer the block value from the source block to the next block using direction of travel based on occupancy changes.

Hi All, as Dave said DigiTrax does allow analog locos to run, 1 only, with address 00. I did all the programming at our club layout which uses DigiTrax and we disabled the analog feature on the

Re: Detecting DC vs DCC track power
I thought that would be the case, but the 'tombstone' detectors (BD20 and clones) still work with DC. What you can do is wire in a pair of LEDs powered off track power. Say one green and one red, 16V
