The death of DCS has been greatly exaggerated. There are many, including myself who will continue to use this system. The responses by members here are their opinions, including myself. Since you indicated you have MTH Proto-2 engines, I recommend you stick with DCS. Remember all Lionel engines can be run with DCS but DCS can’t be run on any of the Lionel systems other than a straight transformer. Even if DCS does disappear I am confident my 5 yr old system will outlive me.
