The western segment is still in use for CSX freight traffic for the Schnitzer scrap yard on the Everett waterfront. or freight to the
Chelsea Produce Market, It is also used by the MBTA to transfer southside commuter rail equipment to and from the
MBTA Commuter Rail Maintenance Facility, and by Amtrak to transfer
Downeaster equipment to and from
Southampton Street Yard. The track
loading gauge is the minimal Plate B. The section of line is owned by
MassDOT, although
MIT owns the land of two segments with an easement for rail use.
Route Genesis locomotive crosses Main Street in
Cambridge. The section of the Grand Junction between the now vacated Beacon Park Yard and the
Fitchburg Line lies mainly in
Cambridge, with short sections in
Allston to the west and
Somerville to the east. The line splits from the former
Boston and Worcester Railroad (after 1867, the
Boston and Albany Railroad) and soon crosses the
Charles River diagonally on a bridge on the
Grand Junction Railroad Bridge, which also passes underneath the
Boston University Bridge (formerly the Essex Street Bridge). It then runs through Cambridge along what was once the shore of the Charles River, and is now a rough border between the main campus of the
Massachusetts Institute of Technology and the rest of Cambridge. From the Fitchburg Line to the
Haverhill Line (shared at that point by the
Newburyport/Rockport Line), the former Grand Junction is occupied by tracks which allow freight trains to move between the four northside main lines. The Newburyport/Rockport Line parallels the Grand Junction right-of-way from there to Broadway in
Chelsea. In Cambridge it diverges from the former
Fitchburg Railroad and crosses under the old B&L mainline (with track connections). It soon crossed the border into
Charlestown, part of Boston. The extension crossed the Mystic River Branch of the
Boston and Lowell Railroad. Just south of Cambridge Street, the Grand Junction junctioned with and crossed the B&M. It then runs along the east side of the former
Boston and Maine Railroad's main line towards Boston. After crossing the
Mystic River, it passes through outlying areas of
Everett and north of downtown
Chelsea. In Everett, freight yard tracks now occupy the Grand Junction right of way.
History Until 2018,
CSX Transportation operated one daily freight to the New England Produce Center and scrap yards in Everett. The
Barnum and Bailey Circus train often parked on the Grand Junction while the circus was in Boston. On October 2, 2008, the state government announced an agreement with
CSX Transportation for the purchase and upgrade of several of CSX's freight lines in the state, including the western section of the Grand Junction. The agreement was signed on September 23, 2009. A first closing on June 11, 2010, transferred dispatching control of the line from CSX to the MBTA's commuter rail operator. The second closing on October 4, 2012, transferred ownership of the Grand Junction and several other important lines to the state, completing the $100 million deal. On November 16, 2012, Amtrak and MBTA equipment moves were limited to over the Grand Junction Railroad Bridge, and freight traffic was not allowed to use the bridges. On November 21, the bridge was closed to all rail traffic due to its poor condition. While emergency repairs were under way, trains moving between the north and south sides of Boston had to be routed via
Pan Am Railways trackage between
Ayer and
Worcester, a lengthy detour. The bridge reopened in early January 2013, but was closed again from March to June for additional structural repairs. The City of Cambridge has done a feasibility study concerning adding a "rail with trail"
multi-use path to be known as the Grand Junction Community Path from the
Charles River Bike Paths at the
Boston University Bridge, through MIT, paralleling Cardinal Medeiros Way northeast of
Kendall Square, and connecting to the proposed extension of the
Somerville Community Path near Twin City Plaza.
Proposals for more western service The "locally preferred alternative" for the
Urban Ring project as of June 2008 calls for routing
bus rapid transit along the Grand Junction right-of-way, from George Washington Park in Cambridgeport, over the Charles River. The existing railroad bridge would be widened to add lanes for buses and the path. In 2010, Lieutenant Governor
Tim Murray publicly discussed branching the
Framingham/Worcester Line over the Grand Junction to provide MBTA Commuter Rail service from Worcester to
North Station. In December 2011, the Massachusetts Department of Transportation announced that "is not pursuing the use of the Grand Junction for increased MBTA Commuter Rail service at this point," opting instead to expand
South Station, which would allow more service from Worcester without the need for a North Station route. It further stated: "However, expanding Boston South Station is an enormously complex and expensive project without a specific timeframe. Should the need for increased Commuter Rail capacity become overwhelming in the period prior to the expansion of South Station, MassDOT might reopen the Grand Junction discussion. The use of Grand Junction for Commuter Rail service could meet some of the needs to be provided by an expanded South Station, at much lower cost and with much less time and complexity." The Grand Junction would have been used to carry
ethanol by rail to a tank farm in Revere as one of three route options considered in a proposal that underwent state safety and environmental review in 2013.
Unit trains consisting of perhaps 60
tank cars would have run at night to deliver the gasoline additive. In the face of community opposition and pressure from the state legislature, the company withdrew its proposal on July 2, 2013, days before the
Lac-Mégantic rail disaster. In 2014, the western part of the line was included in a proposal to connect a proposed
West Station with
North Station, with the creation of an additional
infill station on the line in Cambridge. In October 2024, the
Cambridge Redevelopment Authority (CRA) released a detailed engineering feasibility study of such a transit connection. The study was conducted on behalf of the CRA as part of developer
Boston Properties's efforts to mitigate its development project in
Kendall Square. The study determined that "
urban rail" using
electric multiple units (EMUs) or
battery electric multiple units (BEMUs) was the most feasible mode. The "Core Route", between
West Station and
North Station, would cost between $378.28 million and $667.26 million (depending on whether 2-car or 4-car sets are used, and whether EMUs or BEMUs are used); while an "Extended Route" connecting to
Everett,
Chelsea,
Revere and
Lynn, would cost between $515.9 million and $1,254.03 million. The Core Route, which would have four new stations (including West Station), could receive 6,500–11,200 daily boardings per day by 2040. == Eastern segment ==
