I have come upon a Bachmann G Scale Train set through all of my buying and selling and I dont know anything about it and was wondering if someone could give me some information on it.  It is a Christmas set with a large engine with smoke stack on the front, has a box car for reindeer transport, a caboose, a coal car, and a transport car with packages in it.  It has several sections of track and has the control box and power supply. All of the cars in the train have christmas lights on the side of them that light up when it is running. It has plastic track connectors that hold the track peices together. The cars are very well made and really heavy. I would say that it was an expensive set once upon a time. It appears to be complete, but I havent ran it yet till I check to see if there is anything in particular I should look for before I put power to it.  On the side of the cars it says North Pole Southern and the coal car seems to have some sort of spotlight on the top of it as well as a place to insert a 9 volt battery.  I hope this is enough information for someone to give me an approximate age as well as what to expect as far as a resell price for it.  I can post pictures later if so needed.  Also I have checked eBay and Yahoo and have been unable to find a set with this many track pieces and cars.  Thanks in advance for your time and expertise.
