Hi.

The battery car is for real now:

The circuit board on the end is an up/down voltage regulator.  It keeps the voltage @ 22v regardless of the input.  It cuts the output when the batteries drain to 18.8 volts (3.13 per cell average).

The side board in front of a sliding door  is the voltage/capacity monitor, see next picture.

My G scale BigBoy has arrived at Ray's Electric Trains, he is doing the final tuneup.  Hopefully will have it by next week.  In the meantime I will be trying to get enough real track put down to actually run it a few feet.
