Ha Ha!The same STATE? Used to plugitin and drive off, electric train,
to NYC or Boston.

SOMETIMES I had been held over so I didn't get back in about 8-10 hours
I would CALL the RR shop, and ask one of the guyz to just unplug the car, so
I wouldn't FRY the batteries. Of course I was in a private, protected lot.
Safer than a public place. For that I guees you could have a timer setup?
Just take a few hours worth?
You're miliage may vary, though. I just thought I'd share my times and
setup at work.
