After years of faithful service my Pocono Mountain Lines Auto reverse unit appears to have failed.  There is nothing visible to indicate a component failure but the device no longer responds to occupancy in the "stopping sections", the locomotive runs right on through.  I have made no changes to wiring, the unit is receiving and distributing power to the track throughout the designated line.  Unit was wired to receive fixed voltage to operate the device, track power was provided via an individual throttle from the same transformer.  Previously when there was no track power the unit would cycle if the fixed voltage to the device was active, that is no longer the case.   What device if any is available as a replacement?  An off the shelf turn key replacement would be preferred if such an item exists.

Thanks for the response.  I could not find any documentation for the device on the site.  Before I pull the trigger I want to make sure it will cycle an E unit equipped loco.  It looks like Z stuff makes something as well but theirs requires insulated rails, the PML product worked off of the center rail, sensing current draw.   

Update, after finding one on Ebay and ordering it I decided to remove all the wires, lightly clean them and re-attach even though nothing moved and nothing was ever altered at the board connections.  As anyone can guess the little critter has decided to work again.  I am dubious this was the right corrective action but one cannot argue with results.  It looks like I will have the opportunity to add another piece of automation somewhere else on the layout now.
