Interesting topic and posts. Thanks. Click here to see a web site with articles about S-gauge battery power in general and systems in use and available today. I'm not sure about its use with FlyerChief engines, but am wondering if perhaps the latest FlyerChief-Bluetooth Baldwin diesel switchers could be converted to use it (that way there's no smoke unit to worry about drawing more current that currently available -- pun intended, albeit a lame one).
