Going through a friends large collection of pre-war. He passed and am helping his family as best I can. I know about post was trains but not much about pre-war. Love some help with these. Are they all Lionel or another make I know most are Standard gauge but that's about it. The crossing gate and 50s street light I do know about. Is there a good book I should get about pre-war? There is also a large crossing signal that had to be made for standard gage on the layout. When you turn the layout on all these display signal turn on, should I turn them off? Thank you. Don
Picture will enlarge if that helps.
