The train comes with two cargo cars carrying lumber.  I only have one log piece.  All of the trains say T4194 so I know they go together.  The train uses 1 AA battery.  I tested the train and it works.  It is quiet.  the battery terminals are clean.  I do not ship electronics with batteries.  Overall coloring is good on the train cars.  Dash's eye was fading so I tried to color it back in.
