Believe it was you that did a little research re: Amtrak. If I recall correctly, you found 25M passengers per year, and extrapolated to 70,000 per average day, and speculated it would take no more than 10,000 digEs to fully satisfy demand (and I agree, including devices in rotation).
This brochure says ``all Amtrak routes``, suggesting system wide (making your numbers applicable). 10,000 = $6.35M to EDIG (~$1.25M profit). If delivered in one qtr., that would put us solidly in the black.
Haven`t heard of an order from Wencor to EDIG to support this, so it may be a ways off.
And I KNOW nuttin`!
