@lain@lain.com The CRJ-700 is one of the most popular regional airline jets in North America. It would take approximately 8 CRJs to cover the capacity that a single train could deliver. So a single train could, in theory, replace 8 airline flights on a single route. It'd be safe to assume similar demand in return trips, so that's 16 flights, now. If that same capacity or demand was served let's say twice a day, that's 32 jets. Now you start extrapolating that to other destinations---let's say 4 destinations, for thought experiment. 4 trains going to 4 destinations with full service (there and back return trips) could cover the same capacity as 128 regional airline jets.
