> The Acela has 3,442,188 yearly riders.

Divided by about 200 workdays a year and you end up with about 17,000. Even tripling that as you adjust for things and you probably have less than 25,000 semi-regular riders or better.

That's an odd accounting. Acela isn't commuter rail. I'm sure some people use it for regular commuting, but your numbers seem to suggest that's its primary use. It's not.
