And here's the new and improved up ramp. I used various pieces of wood underneath the styrene sheet I used for the support of the ties. The area under the styrene is in the process of being back filled with "goop".
I completed the scenery around the ramp, and installed the ties and stained them. Getting ready to lay the rail.
The next photo shows the final result. This worked much better for the GP7. All but my largest steam engines were able to make the grade.
