Next summer I was thinking about buying a 15 day, 8 segment USA Rail Pass and do some touring out West. I would start and end my journey in Pittsburgh, PA. Leaving PGH on the Capital Limited at 11:59 PM. Would that one minute before midnight use up one day of my Rail Pass? What if the train is late and I don't board until after midnight? That one minute would keep me from spending an extra day out West ! Also is there a way to check how many segments you have used while on your journey? Thanks in advance for any help.
