Donner Pass - UP era

It's Spring Break ans on top of the continuous work of testing and modifying steamers (I haven't been able to do much of that lately - school's got me swamped with 21 credit hours
) I've decided to upgrade Donner Pass to modern-day.
Anticipated changes:
Adding working platforms at Roseville, Auburn, and Colfax
Removal of main track 1(?) just outside of Norden (Does anyone know if the turntable is still there?)
Extending Roseville yard
(Somehow) partially tunneling under Reno, Nevada
I've just barely started work and I have to say that there is so much that has changed in Roseville! Part of the receiving yard near the servicing facility was apparently ripped out, the yard entrance has been extended way out near the first overpass outside of Roseville, and the actual layout of the engine facilities has changed a lot.
Here's the yard entrance extension (I'll work with the crossings later):
Here's the Amtrak platform (by the way on of the main tracks here was also apparently ripped out):
And here is some of the work going on at the servicing facility:
There is still plenty of work to do just in Roseville. I've got my work cut out for me.
