I was just given a huge box which contains the Bachmann Big Hauler, Green Lightning train set

Billsharron posts on the Bachmann forums under the moniker "Loco Bill Canelos". He's still collecting info, and I have emailed him the link to this thread.

the Set number on the box is: 90101.

I've never heard of anyone collecting Bachmann 'Big Hauler' sets. Bill collects the info, but not the products!
Your price is perhaps a bit low, as the cars in the set are normal Bachmann freight items. However, the loco has plastic driving wheels, which makes it short-lived as the wheels wear out. But for a kid starter set, or something that is only brought out at Xmas, it will work. I still have a loco on a shelf in my office.
The Bachmann Forums can give you information about the batteries, and the alternate rc battery cable that should be somewhere in your box.
