This project involved the installation of up to two track miles of continuously welded rail (CWR) on the controlled passing siding in Northampton, Mass. on the MassDOT-owned Connecticut River
Main Line.

This siding, which is the track on the right in the image above, runs from a point just south of the bike underpass to the crossing at Highway Auto Salvage.

The project also includes thermite field welding at various locations along the Connecticut River Main Line.

This work is scheduled to take place during the summer of 2022.

Springfield | Riverfront park access project (2023– )

The City of Springfield has proposed that a new entrance way to River Front Park be constructed.

The proposed improvements, shown below, would replace the existing surface level parking lot on the east side of the tracks with an Americans with Disabilities Act compliant pedestrian path to the existing underpass at.

January 15, 2021 | The state Transportation Bond Bill that was signed by Governor Baker included $1.5 million in funding to improve access to Riverfront Park in downtown Springfield.

March 8, 2022 | Amtrak offers a $3 million contribution towards the cost of Riverfront Park access project. As part of the agreement Amtrak would be permitted to permanently close the State Street crossing.

Springfield | Track Reconfiguration Design Project

The Massachusetts Department of Transportation (MassDOT) intends to prepare preliminary engineering design and environmental clearance work for significant track, signal, and infrastructure improvements around Springfield Union Station.

These improvements include additional platforms, additional crossover tracks, storage tracks, a new layover facility, and other work that will support the Amtrak Springfield Line, the CSX Boston Albany Line, and small segments of the former Armory Branch (to the east of the station) and Connecticut River Main Line.

This project would improve operational efficiency, reduce travel times, improve passenger accessibility for intercity passenger rail services, and reduce freight and passenger rail conflicts on the rail corridors in the Springfield area.

The final design, among other things, most likely will include track work that would eliminate the need for Amtrak’s Valley Flyer trains to back in and out of the station, and for Amtrak east-west trains 448 & 449 (the Lake Shore Limited) to stop on a low level platform in Springfield rather than on the new high-level platform.

This project lays the ground work for a significant increase in train and passengers traffic at Springfield Union Station in the coming years.

Conn River Main Line Bridge Work | MP 3.6 & MP 7.97 (2022)

This project calls for the repair and rehabilitation of two existing steel railroad bridges on the Connecticut River Main Line, in the cities of Chicopee and Holyoke.

The bridge at MP 7.97 — which carries the railroad line over the Second Level Canal and Lyman street in Holyoke — is a 336-foot long 3-span open deck bridge.

The bridge was built in 1928 by the Boston Bridge Works. The inventory record, which can be found on the link below, indicates that the bridge replaced an iron lattice truss bridge that was built on the site in 1887.

The bidding documents state that the project must be substantially completed during a planned 3-day track outage that is scheduled to start on Friday September 9, 2022 @ 1:00 am and end on Monday September 12, 2022 @ 3:00 am.

Connecticut River Main Line PTC project (2021– )

MassDOT is moving forward with a project that will bring a safety system known as Positive Train Control (PTC) to the MassDOT-owned Connecticut River Main Line between Springfield and the Vermont state line.

The Connecticut River Main Line, which is often referred to as the Conn River Line or the Knowledge Corridor, is used by Amtrak’s Valley Flyer and Vermonter trains, and the freight operator Pan Am Railways.

Notably, the Conn River Line is the only rail corridor used by Amtrak in Massachusetts that does not have PTC installed and in use today. The other rail corridors that Amtrak operates on in the state — the Northeast Corridor, the CSX freight line west of Worcester, the MBTA Commuter Rail network1, and the Amtrak line south of Springfield — all have PTC installed and in use today.


June 21, 2021 | The MassDOT Board of Directors approved a $65 million multi-year project to add Positive Train Control (PTC) to the Connecticut River Main Line as part of the SFY 2022 Capital Investment Plan. The plan detailed $15 million in spending for the project in SFY 2022.

February 16, 2022 | During the MassDOT Board of Directors meeting it was announced that plans to procure long lead materials have started for the PTC project on the Knowledge Corridor. It was said that, “final design will be completed this year and construction will be completed over the following two years.”

May 18, 2022 | During a presentation to the MassDOT Board of Directors the Rail & Transit Administrator reported that MassDOT is working with Amtrak to pursue federal funds for the Knowledge Corridor PTC project.

1 The entire MBTA Commuter Rail network also has PTC installed and in use today.

NECR Freight Corridor Upgrade (2021– )

In February 2021 the MassDOT Board of Directors agreed to move with a project that will upgrade the 55-mile New England Central Railroad (NECR) corridor in Massachusetts that runs between Monson, Palmer and Northfield.

The project, is funded roughly 1/3rd by NECR, 1/3rd by MassDOT, and 1/3 by the Federal Railroad Administration.

Presentation to MassDOT Board of Directors | February 22, 2021

The project includes the replacement of 22.7 miles of jointed rail with continuously welded rail, the installation of 30,000 wood ties, the replacement of 30 turnouts, the installation of 25,000 tones of new stone ballast, the alignment and surfacing of 54.7 miles of track, and bridge deck repairs on 16 structures.

The project, which should be complete in early 2024, will increase the maximum allowable gross weight for freight cars moved on the NECR line from from 263,000 lbs to current national standard which is 286,000 lbs.

Connecticut projects of note

Enfield, CT | New Hartford Line station (2023– )

Status: In Design

This project will add a new Hartford Line station stop in Enfield, CT.

The project includes a includes a single high-level platform, transit connections, parking, and improvements to the railroad bridge over Main Street.

Enfield station is important for our region because once it opens it will become the station of choice for people living in Agawam, East Longmeadow and Longmeadow due to its close proximity.

The project is scheduled to be put out to bid in May 2023 with constructions started later that year.

On September 14, 2022, Governor Ned Lamont joined state and local officials to officially break ground for the project, which includes a new train station and roadway safety and track improvements in the Town of Windsor Locks.

The new station, which will be located just to the north of the historic Windsor Locks station building, is expected to open in 2024.

The station will include one 500-foot long partially covered high-level train platform.

The planned surface parking lots at the station is designed to accommodate 159 vehicles.

The station will also include a loading/unloading area for connecting bus service to Bradley International Airport.

The new station is important for western Mass for two reasons —

  • Windsor Locks is currently the station of choice for people living in Agawam and Longmeadow due to its close proximity, and
  • This new station will be the transfer point for the bus connection between the Hartford Line and Bradley Airport.
