I started this tread on Zealot, but I am restarting it here.

The 'table_diagram' is draw on 2 ft squares and I used 24" main line curves. My plan is to stay less then 2% grades. This an HO layout and it is my second RR. The first one was over 30 years ago and was 8X4 ft sheet of plywood.
1
The bench work goes around the wall in a U shape and then connects to the island in the middle of the room. You can walk around the island and between the table along the wall and the island. The island is 7 inches higher than the bench work along the wall.
2
The island will have a mountain in the middle do the double main line enters the mountain by one large tunnel and out the other side by two smaller tunnel exits. Track continues to elevate enough to cross back over the line entering the island and then drops back to match the other side of the double main line and the back down the hill.
3
I have drawn a few freight business along the main line.
The wall picture is a show my latest plan. Assuming the North is up in this picture the West bound train will be on the inside main line track. It can enter the freight yard on the left side or go around by staying next to the East bound main line. If it is a passenger train it can enter the passenger yard on the top left side of the picture. There will be two passenger loading tracks and a third track to allow the engine to escape and back up to the main line. To get service it will then need to move forward and then back into the freight yard, and then into the service area with the turntable.
After the last turnout at the top the track will drop so that it can go under the yard track and then back up to be at the same elevation as the other main line by the time it reaches the island.
With the current design the grade from there to the island will need to be about 3.5 %. Is this to much? Should I lower the island some?
