I don't buy the need for wider guage. Secondly, as we well know from IRT v BMT v PATH, standardization/compatability have long termvalue. As for creeping around curves,that has little to do w/track guage; its theradius and easing of the curves that set the speeds.

CTA ran PCC L cars at 76.xx in the early 60s on the North Side 4 track main express tracks to show it could be done. CNS&M ran tests w/ the Electroliners in excess of 100MPH in the 40s on ROW laid out in the 20s.

As to duble stacks, freight in general, the major constraint on decent mainline RR performance is managerial not technical.
