Lets do this, from a Baltimoron's prospective (aka me):
Acella: 35 min on average DC to Baltimore. Maybe stops at the airport. At least $44 one way if you want to go now.
NE Regional: 45 min on average, 2 intermediate stops, at least $15.
MARC Penn Line: 1 hour on average, local service has 7 intermediate stops. $8 flat.
MARC Camden Line: 1h10m on average, 8 regular intermediate stops, $8 flat, actually puts you downtown.
Maglev:
- Washginton to Baltimore, with intermediary of BWI Airport. From DC: Up NY Avenue to Langgdon, then continue in a straight line to Bladensburg. Arc gently northbound under MD 295, and follow under it to MD 35 and Ft. Meade. Continue straight under BWI, stopping there under the parking garage. Then arc north to ether Cherry Hill, Patapsco, or Camden Yards for final destination. Most of the trip is underground.
- The most recent press report claims an 8-15 minute ride for on average $60.
That's...
Lets add some more context:
- Acela: Boston-NY-NJ-PA-MD-DC and back, as fast as possible on existing infrastructure, limited stop, better on-board service for a premium price.
- NE Regional: Boston-NY-NJ-PA-MD-DC-VA and back, slightly better than commuter style, still reasonably fast. Granted, Boston to Newport News is a good chunk of a day.
- MARC: Commuter service between Baltimore and DC. It's cheap but if you live "north of DC" it's better than dealing with traffic.
Maglev as planned: Overpriced, stupid-fast... uber-subway service. It's a trial. It's so lobbyists can get to DC faster but not
live in DC (probably because the beer and theater scene is a bit better). If they do Mt. Vernon to Camden Yards, they'll get the baseball/football traffic (which makes it sketchy considering how MARC got burned by the feds on baseball trains). It's just a waste of money that should of been spent on the B&P.
