Double tracking Donner Summit

[cacole]

I'm surprised to hear that they're going to double track Donnor again because their current project of double tracking the Sunset Route across the southern part of the country is so they can route more traffic away from Donnor's steep grades and heavy snows.

I see that Union Pacific is working very hard at track work over Donner Summit. Talk is that they are going to double track Donner Summit again and undercut the snow sheds and tunnels to accomodate double stack cars. What is the time table for this work? Does that mean they are giving up on the Feather River Route? How many trains do they project for Donner vs The Feather River Route?
