It's becoming obvious that battery power is here to stay. I have done over a dozen OGauge battery power conversions with various wireless RC systems and all are running well today. I converted a LionChief+ to battery power two years ago and it's fine. OGRR magazine RUN314 includes a complete description of a battery powered BlueRail controlled RS-3 diesel. But, for the record, I still can run conventional AC or DC and TMCC. When done carefully and properly, battery power works just fine.
