Is anyone making new battery powered O gauge locos? I've Googled them a few times and had almost no luck. I did just won a vintage battery powered Marx on eBay but I haven't seen anyone making new ones. (My K-Line Christmas train being the exception and it is now discontinued.) I've still got a box of old O27 track in my garage but it's too rusty to run electric through it anymore. I've got some Teflon coating to spray it with to keep it from getting worse so I figured I would use it for an outdoor layout and run battery power on it. How hard would it be to convert a loco over to battery power from electric?
