There should be a website for collectible trains. Search the web. Google "bachman trains value" or something like that.
Bachmann is a very good name in the model railroading hobby. You should not have a problem selling them on Ebay. The trains can cost any where from $40 to well over $100.
Many modelers today want DCC trains (trains with advanced controls) but plenty of people want older trains.
Just look them up on ebay and see what other people are selling them for.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
