Re: AutoReverse Modules
As you have an NCE system, like me, for an auto reverse unit you must use a
DCC manufacturer not the same as your system. NCE does not make any auto
reversers and have them marketed under the NCE brand. There is no
The Digitrax PM42 will most probably work on NCE, but if it required
"adjustment", then this could only be done with a Digitrax throttle.
For users of any DCC system, other than Digitrax, I would only buy units
manufactured by anyone other than Digitrax. These include Tony's Train
Exchange - PS Rev Power Shields. MRC's - AD520 and Lenz's - LK100.
See Tony's site for details for auto reversers at:
For using the auto reversers on return loops see the above site and Allan's
There are no cheap and simple solutions for "return loops" that operate
automatically and "transparent".
My recommendation for an auto reverser would be Tony's PS Rev. These are
solid state electronic units. I have seen and others have reported problems
with using mechanical relay types of auto reversers. They may cost a little
more but they offer trouble free operation to everyone that uses them.

Thanks for your replies. Yes, I actually have 3 auto-reverse areas and 1
turntable, this is why I was going to use the PM42. I'm using a NorthCoast
DCC unit. Reading the forum I think I would need a DigiTrax throttle to
change any settings to make the PM42 an autoreverse module. Is there any
around this using the Northcoast since I've already purchased it?
I still have the option to return the PM42 and go a different route.
Is it better with DCC to stay with the products that are the same brand as
your control unit?
Marcus, I will be using the autoreverse module as a return loop. Do you
have any suggestions?
