No chips or cracks that I can find, looks great, but doesn't light up.  Tested A/C adapter, and putting out correct voltage as specified. Looks great otherwise, and it appears that when plugged in, the output voltage at the back of the coal car is also good, suggesting that plugging any cars in behind it should work fine.  I don't have another one at the moment to test.  Please ask any questions prior to bidding.
