Since this station will be the terminal for the Commuter Rail, it will handle a lot more passengers than the station normally would, as it has to handle loads near what North Station would
Not quite... it will be the terminal for the Reading/Haverhill line, not the entire commuter rail system. No doubt it will be busy, but nothing near as busy as North Station is. The good part about this particular line is there has been a sort of "dress rehearsal" going on for the past month and a half, as off-peak trains have been bused from Oak Grove due to a tie replacement project. Everybody's been-there-done-that, and will know precisely what to do at DNC time.
