I just got this locomotive and my first impression is that Bachmann has delivered a good product for the money. The may be some minor flaws here and there but overall it looks great. Later I will post how I feel about it's running qualities.
After a little research I have found out a little more about 2680. It has the low mounted headlight and Blomberg M trucks. Had Bachmann done a little more research they would have found that GP38-2s numbered above 2703 have the high mounted headlight and some have the old style blomberg trucks.
I will probably renumber my unit
