Editing MBTA Commuter Rail (section)

=== North–South Rail Link ===
No direct connection exists between the two downtown commuter rail terminals; passengers must use the [[MBTA subway]] or other modes to transfer between the two halves of the system. (For non-revenue transfers of equipment, the MBTA and Amtrak use the [[Grand Junction Railroad and Depot Company|Grand Junction Branch]].) The proposed [[North–South Rail Link]] would add a new rail tunnel under downtown Boston to allow through-running service, with new underground stations at South Station, North Station, and possibly [[Aquarium station (MBTA)#Central Station proposal|a new Central Station]]. A feasibility study was conducted in 2018.<ref>{{cite web |date=June 2018 |title=North South Rail Link Feasibility Reassessment |url=https://www.mass.gov/files/documents/2018/06/29/NSRLJun18_PubPres.pdf |url-status=live |archive-url=https://web.archive.org/web/20191130002146/https://www.mass.gov/files/documents/2018/06/29/NSRLJun18_PubPres.pdf |archive-date=2019-11-30 |access-date=2021-04-12 |publisher=MassDOT}}</ref>
