The rules are located on the NMRA website:
1. Missing a service track for locomotives (must hold two locos for Electrical)
2. Measured track by CAD at 112', more than 75 feet required
3. Six examples of track:
- Passing siding
- Reversing loop
- Super elevation
- Grade elevation
4. Construct for merit judging
- Gantlet track
On Civil it looks like the only problem is a service track, so we'll add that
1. Need sixty square feet in O scale, and we have 71 feet.
We'll be good on everything else.
Big problem...need a yard
One yard with a minimum of three tracks and a switching lead independent of the main line.
Ok...let's fix this yard problem:
This adds a bit more track than I care for in this area, but I can always remove it and go back to the single track design. The main line extension also makes for a nice switcher pocket.
Now, for the loco storage and servicing:
There really isn't a whole lot of room anywhere, so I put it in the only remaining spot left. This might be a good spot for a "shadowbox" area. Here we have an engine shed and enough track for two locos, plus servicing equipment. We'll put an inspection pit in the shed and make it count for one of our trackwork items.
I think we are done! AP here we come!
