I'm have bought to much and should lighten what I have. No, I don't want to but my layout is only 8' x 10' and how much could you put on a layout that size. I need to sell engines and rolling stock. I looked on E-Bay as to what the value is and wasn't happy with the sale value. I didn't buy things to make money but to sell things at half of what I payed is bad. I would sooner keep everything. Any ideas? How do you know worth? Lionel is easy but MTH, Weaver, Old K-Line, and Williams there is no books I know of. Thanks for any information.
