Relative to the question about inventory. I too have been using Excel with columns for item number (manufacturer) and description, date purchased, price, from whom and any comments relative to repairs or where the item is located. I also use the same spreadsheet for the circuit assignment(s) for the transformers. Each item has a hyperlink to a photo of the items. The photos are organized by year of purchase with a separate folder for materials like light bulbs. It's a lot easier when the spreadsheet is updated when a purchase is made.
I have been continuing to paint the rails on the tinplate track.
