My layout is U shaped 13 feet down the south side, 8 feet across the end and up another 11 feet on the north side. The top of the U is joined by two large bridges. My layout is not any given period as I love the look of old and new engines so collect them all. As Steve would say "Not your prototypical railway - NYPR" . All the photos are of the upper level of my layout which is only DC.
