Hi all-I welcome any constructive comments you might have on this layout. It’s not totally done, but I think done enough to get some input. Here are a few thoughts that went into it:
- Scale is HO
- Overall size of the table is about 11 x 9 feet.
- There are two main tracks - capable of running two trains simultaneously in opposite directions.
- Radii for the main tracks are 22". I’ve built easements into the turns (as I learned from this forum).
- Radii on the spurs/siding is 18".
- Turnouts are intended to be Atlas #6 (on the mains) and #4 (in the yards).
- Grades are intended to be no more than 3%.
- The shaded picture shows roughly where the tunnels may go (obviously will have some better shape).
- The other picture shows the centerlines of the track a little better. I hope the drawings are legible.
- The upper LH and RH areas are TBD future industries (spurs not yet drawn in).
- It’s for my 7-year old son and I. I want to him to be able to reach most of the layout. He thinks it’ll be real cool to have to crawl under the table.
Please let me know if there’s anything that doesn’t look quite right. Thanks in advance for your assistance.
