I don't have my layout on a board yet. Still planning it using freeware track planning software SCARM: SCARM - Simple Computer Aided Railway Modeller - Freeware program for design of model railroad layouts and track plans

So dig out the old train sets and see what you have. You may find that they are worth a goodly sum of money. I have an old 60's vintage Marklin 3025 3-car commuter worth around $2K.
