I really don't see rail expanding in the US in my lifetime for many reasons, including our national debt, the loss of the dollar's reserve status, the similar functionality provided by trucking (negative externalities like pollution, shared cost of road upkeep, and employment levels notwithstanding), the right of way vs NIMBYISM of expanding rail and running extra lines, and finally the inability to complete infrastructure projects in the US on time, in budget, and with quality. I am just not optimistic about any of this.
