It's 5:52 a.m. in Moynihan Train Hall. Sienna Sullivan is balancing a container of fruit and her water bottle in one hand while tightening the straps of a backpack that's weighed down by two laptops with her other. It's the start of her twice-weekly commute between New York City and Washington, DC.

More importantly, she has learned how to turn eight hours on Amtrak trains into one of the most productive parts of her workweek.
