Hello all, I'm new here and just starting to rekindle my interest in model railroads. My children are now of the age(4 & 7)to enjoy them as much as do. I recently unpacked some old Lionel steam locos that my uncle had given me many years ago, they haven't been ran in over 25 years. I would like to set up a 4x8 layout for the kids to enjoy and then I'll start on a HO layout after that. Questions: 1. What should I use to clean the steam locos? (The youngster in the local hobby shop wasn't very helpful.) 2. What should I use to clean the track? It's 3 rail, not sure if its O or O27, some pieces are slightly rusty. (Wouldn't you be if you were in a dark box for 25 years?) On another note my brother and I are begining to go through our grandfathers boxes of trains. (No idea of how long these have been boxed up, he passed away in 1983.) We have found many very old trains, we have a price book for pre & post-war Lionel and a book for post-war American Flyer. We haven't been able to find much information on pre-war AF. (Again the youngster at the local hobby shop wasn't very helpful.) We also have some old Marx and Hafner trains, no clue on age or value. Questions 3. Are there any websites that have more info and prices on these trains? Thank you in advance.
