Super Bad Idea -- State's Orange Line platform provides an ideal connection to DTX Orange Line Platform -- very short amount of tunneling is needed
Make the connection NOW and then plan for an upgrade that will make DTX the true Master Station
From one entry point on Washington St a T commuter would have access to :
- All Green Line Trains at Park via the existing pedestrian tunnel
- All Orange Line Trains at DTX [existing Platforms]
- All Red Line Trains {except Mattapan Line] at DTX or Park depending on crowding, etc.
- All Blue Line Trains at State via the new pedestrian tunnel and existing pedestrian connections at State
- All Washington St Silver Line Service at DTX or Park
- All other Silver Line Service via one stop on the Red Line to South Station
After a period of time to try this out -- the next phase is moving walkways to expedite service
Final phase of the DTX Master Station Project -- provide a connector with moving walkways from the Summer St end of the Red Line platform to a new Head House near to Winthrop Square
The T and most transit systems are way way behind airports in the use of moving walkways -- which now can climb and descend and go around curves
