I am rebuilding my old HO setup--converting to DCC and 83 scale track.
I have an old (bought in late 1980s) Bachmann 2-8-0 Loco w/smoke (part number 654, Great Northern).  Are there any part lists or exploded views available? Maintenance guides?
How hard would it be to convert to DCC?  Is it expensive or worthwhile?
Thanks for any help or guidance.
