I have to wonder... If Warren Buffett was scheduled to ride the Empire Builder on Monday, would his train suddenly find itself amazingly on-time all along it's run?
I see this as Amtrak's issue only because they operate the train, but it is really BNSF's issue which is compounded by their unwillingness to do what would be the only real solution: double and tripple-track the entire length of the Hi-Line. Make it a Northern Transcon, built and operated to the same standards as the southern one. Yes, it would cost nearly one Billion US Dollar's worth of construction, but BNSF also posted a profit of over $3.3 Billion in 2012. The demand is very clearly there, is only increasing each and every month, and the line is overwhelmed. It's a mess.
To those still dreaming of a second-daily EB at some point in the future, I do believe there is a better chance of the poles reversing and a full-blown colony on Mars these days.
