Goodbye Daggett-Edwards, hello Cajon Pass

I am putting a boring desert route on hold to work on a more exciting California desert route. I am now doing Cajon Pass. This one will go from just south of Colton(including the diamond intersection with the UP Alhambra/Yuma Sub) to the Barstow Yard, where it will then meet with the BNSF Mojave/Needles Sub.

Here is my mere progress so far:

I am already working on the Barton Rd. overpass, which is a major pain. I need to make sure every overpass and tunnel has enough clearance for double-stack container trains.The Barton Rd. overpass just barely made the cut for that test.
