Here's a novel solution
Don't bother digging a big hole for transit vehicles -- dig a much smaller hole for a moving walkway such as ThyssenKrupp Elevator Iwalk
Currently each segment is limited to 100m although that is changing with new innovative linear induction drives [no chains and sprockets] -- see accel in development
from their 2015 pdf
[urrl]http://thyssenkruppelevator.com/downloads/iWalk_advantages.pdf[/url]
https://www.thyssenkruppelevator.com/downloads/EscalatorCatalog.pdf
-- here is the capacity
Sao Paolo, Brazil
Note if the slope is minimal there is no need for a pit the walk just sits on top of an existing floor
So here's the basic idea -- leave South Station at the Mezzanine level and cross the Fort Point Channel essentially under the Summer St. Bridge have portals [Charlier Card or contactless] @
in the other direction leave South Station at the lower level
Only one drawback is speed today is limited to 0.65 m/s or 125 ft / sec so the complete trek from South Station to North Station would be about 2 km and at say an average of 0.5 m/sec -- today that would take 4,000 seconds
However, the new linear induction drives with acceleration for the long hauls can get up to 2m/sec cutting the time to 1000 seconds

Anyway -- time to think way outside the traditional box

Nominal Pallet Width 64" width [1600 mm]
Truss Width 7'-01/4" [2140 mm]
Pit Width 7'-25/8" [2200 mm]
Persons per Hour @ 100 fpm (0.5 m/s) 15,750
Persons per Hour@ 125 fpm (0.65 m/s) 20,475

So here's the basic idea -- leave South Station at the Mezzanine level and cross the Fort Point Channel essentially under the Summer St. Bridge have portals [Charlier Card or contactless] @
- Summer & Harbor Walk
- A Street
- West Service Rd. Extension [needs a name change desperately]
- BCEC [West Side Dr.]
- Lawn on D
in the other direction leave South Station at the lower level
- and head parallel to the Red Line Tunnel to a Portal @ High Street
- and then follow High Street to Federal St Portal
- and then Follow Federal St with Portals @
- 111 Federal [aka Great Room]
- Franklin [BofA]
- Diagonally to P.O. Square [Leventhall Park]
- Follow Congress to Portals @
- Milk St.
- Congress Square
- Blue Line -- the long missing Red / Blue Connection also Orange
- Backside of City Hall Plaza
- Bulfinch Crossing [Green & Orange]
- Diagonal to Friend @ Market
- Follow Friend to Portals@
- Valenti Way
- Hub on Causeway
- North Station -- the long awaited connector between North and South Stations
