While getting christmas decor down, my mother stumbled opon a vintage Bachmann train set.   Inside the shipping box from Sears contains the following items, which are all still wrapped.
Northern 4-8-4 loco with smoke- Burlington
52' tender
Wayside Warehouse
Union Pacific crane car
Shell Tanker
3 box cars
1 flat car with logs
track
trackside accessories

Just curious on about how much this set is worth so I would know if I need to keep up or let my son play with.

Thanks for any help
