Golden Classic Series

[bobby j]

I have a Bachmann Big Hauler, Golden Classic Series, Chicago Milwaukee, St. Paul and Pacific Train set, but

have no paperwork, instructions etc. The Original box is quite fadded and I cant find a year made, or what it

may be worth. It is in very good shape, and I might want to leave it to my Grand child, but don't know how 

obtain information, parts, etc.  Any help would be appreciated!! The box say Limited Edition on it and I

believe it is G-Scale?
