Any of you that have operated on the IPP&W, know that Fred and Co store their rolling stock between sessions in bread trays. They have a couple of sheds with racks. At the end of each session, the cars are put in the trays based on location, and pulled out again at the start of the next session. Nifty idea! So, last year, a local nursery went out of business, and they had, literally, hundreds of bread trays for sale for $1 a piece. I bought a bunch. Over the last week, using a bunch of scrap 1x stock, I built me some racks!
Three sets of 7 racks a piece. I can fit 3-4 pieces of rolling stock in each tray. Now I can clear out some workshop space!
