Reply to "Would like to upgrade Atlas SD35 to cruise--need clarification on ERR upgrade needed"

Just to throw another cruise variable, what I have done is to replace the driver board with a Lionel 691DCDEB01; its a back emf driver that fits into the same heat sink; believe Jon Z developed this for Lionel; have installed in engines that use the Lionel modular electronics as in your Atlas SD loco. Get nice cruise from this at a good price. Sure Guns and others have done the same mod. Just another idea as it is a plug in upgrade as the ERR M. Falcon70
