I received a G-Scale 4-6-0 Northern Express Complete Set as a gift.  It was sold back in the 80's.  Do you have other products that go along with this set?  Do you have another set like it?  Could you please give me more info about this set?  This set was not used.  It's still in the orginal boxes and it is in excellent condition.  I am scared to set it up and use it fearing that it will take away from the value of this set.  The engine has the # 10 on it.  Does that mean that it was the 10th engine made for that type of set?  Any info you could give me would be great.  Thanks so much.
