===Lines===
The system consists of twelve lines – four of which have branches – radiating from [[downtown Boston]]. Eight "southside" lines terminate at [[South Station]], with four (Framingham/Worcester, Needham, Franklin/Foxboro, and Providence/Stoughton) also running through [[Back Bay station]]. Four "northside" lines terminate at [[North Station]]. The lines vary in length from the {{convert|9.2|mile|adj=on}} Fairmount Line to the {{convert|62.9|mile|adj=on}} Providence/Stoughton Line, with typical lengths in the {{convert|25-40|mile|adj=on}} range.<ref name=bluebook /> The system has {{convert|429|mi|km|-1}} of revenue trackage and covers roughly the eastern third of Massachusetts plus central Rhode Island.<ref name=bluebook /><ref name=mbtaptc />

Most lines do not share trackage outside the Boston terminal areas, with several exceptions. The Providence/Stoughton Line and Franklin/Foxboro Line both use the [[Northeast Corridor]] between {{bts|Readville}} and South Station, with the Needham Line also sharing the tracks between {{bts|Forest Hills}} and South Station. The Fall River/New Bedford Line, Kingston Line, and Greenbush Line all use the Old Colony mainline between South Station and [[Braintree, Massachusetts|Braintree]]. The Haverhill Line and Newburyport/Rockport Line share tracks between North Station and near {{bts|Sullivan Square}}.<ref name=bluebook /> A small number of Haverhill Line trains use the inner Lowell Line and the [[Wildcat Branch]], while some Franklin/Foxboro Line trains (including all weekend trains) use the Fairmount Line rather than the Northeast Corridor. Several [[Amtrak]] intercity routes run on MBTA tracks: the {{lnl|Amtrak|Acela}} and {{lnl|Amtrak|Northeast Regional}} over the Providence/Stoughton Line, the {{lnl|Amtrak|Lake Shore Limited}} over the Framingham/Worcester Line, and the {{lnl|Amtrak|Downeaster}} over portions of the Lowell and Haverhill lines.<ref name=schedules>{{cite web |url=https://www.mbta.com/schedules/commuter-rail |title=Schedules: Commuter Rail |publisher=Massachusetts Bay Transportation Authority |access-date=February 17, 2025}}</ref> Private companies also operate freight service over much of the system (see {{section link||Freight service}}).
