A little more on the anticipated schedule:
FRI PM Eastbound: works for weekenders, but there is a capacity limitation due 1700 BON departure and train requires 60-mile deadhead
SAT AM Eastbound: starts at BRU, so attractive only to a few Maine-based overnighters and day-trippers (most of whom would have to leave their homes before 0700- rule out families); otherwise a deadhead
SAT AM Westbound: Other than possibly folks returning from an extended stay, train will only serve a few locals wanting to go west.
SAT PM Eastbound: may be attractive to a small segment of MA/NH overnighters (Very small. How many people will travel up to 6 hrs or more each way for an overnight trip?)
SAT PM Westbound: return of the few Maine daytrippers and a few more of the extended stay folks. Otherwise virtually empty.
SUN AM Eastbound: starts at BRU, see Sat AM EB
SUN AM Westbound: Some early weekender returns?
SUN PM Eastbound: may be attractive to Mid-Coast residents who went west the day before, otherwise...
SUN PM Westbound: return of the flatlanders
This service is reortedly designed for flatlanders, correct? For them, there would be only only three EB options per week. Friday's will have extremely limited capacity; Saturday's is largely only practical for week-long stays (given the transit time), and Sunday's precludes anything but a week-long stay. The longer the stay, the greater a tourist's desire would be to have a car. And they augment those three eastbounds with twice the number of westbounds. This will be the empty-seat express.
Who's willing to place a friendly over/under bet on 2018 ridership?
