Auto Reverse Module – Digitrax and MRC Cab Controller Compatibility
William posted this question to readers:
“I have On30 and M.E. track and turnouts and DCC Cab Controller. I would like to install an automated reverse loop (does not to be that big as I will be running Porters with a few mining cars.)
I am electronically “challenged” and could use advice on what all I would need to set it up. I am in the planning stage now but I would like to know how to wire the turnout and loop section up front to see how feasible my idea is to have trains running on a continual basis in and out of the loop without needing to be manually operated. Is a module AR1 or the like all that is needed or do I need some type of ‘block’ detection? And are Digitrax and MRC cab controllers compatible as far as these loop modules concerned?”

Hi William
A digitrax AR! will work with any DCC controller as long as you follow the instructions for wiring it to your track.
William;
As Kevin stated the AR1 will work with any DCC system. A few things that Digitrax doesn’t tell you though. Leave a few inches of live track coming off the turnout before the insulated joiners for the loop track that ill be connected to the AR1, if you are using live frogs. This is not always required but it is easier to do from the beginning.
I had to extend the booster short circuit shutdown time. This is easy to do with a digitrax system and probably with others also but I only have experience with Digitrax. Failure to do this will result in the booster shutting down quicker than the AR1 can switch. Your train will simply stall upon entering or exiting the reversing loop as it experiences a short. Do this often enough and you will be buying a new decoder.
Install the AR1 where it is accessible in case you have to adjust the sensitivity in the future.
