Trains for two and perhaps three lines can terminate at North Station but most of the time it would not be possible to space out the outbound trains to make up for delays during their inbound trips. Trains would have to leave as soon as they change ends (Actually the same problem exists at Government Center today.)
Some outbound scheduling improvement could be had if trains can be stacked end to end on the tail tracks and operators could swap consists, namely the next run (any destination) to go out outbound takes the consist that is closest to the station at that moment. All the consists would have to be the same, that is, no three car trains.

Build something. Anything.
