PTC for the Connecticut River Main Line

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.


February 16, 2021 | At 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. Final design will be completed this year and construction will be completed over the following two years.

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

NECR Freight Corridor Upgrade

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.

Springfield | Riverfront Park Access Project

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.

The new station, which would replace the current Amtrak-owned station at the south end of town, will be located just to the north of the historic station building.

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

The platform will include guardrails, bench seating, trash and recycling receptacles, blue light phones, passenger information display signs and variable instant messaging signs.

The planned surface parking lots at the station will 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.
