MassDOT has been awarded $108 million in funding from the Federal Railroad Administration (FRA) for corridor infrastructure projects between Worcester and Springfield as part of the “Connecting the Commonwealth: Early Actions for the Inland Route Project” grant application.

The planned project would include the following major elements:

  • Infrastructure improvements (as detailed in the diagram below) that will result in increased train speeds and additional corridor capacity along the 53-mile section of the CSX Boston & Albany Line between Worcester and Springfield.
  • The extension of existing passing siding capacity and other track improvements will increase the Maximum Authorized Speed for passenger trains to 80 mph (where track geometry allows) and minimize train delays along the 44-mile single-track segment.
  • Increased operational efficiency and flexibility by reducing passenger and freight train conflicts and reducing travel times along the remaining single-track segments on the CSX-owned segment between Worcester and Springfield.

Connecticut River Main Line Bridge 7.07 Rehabilitation

Rail & Transit Division July 2025 Report – page 5
MassDOT Board of Directors Meeting | July 30, 2025

The Rail and Transit Administrator has announced that MassDOT is planning to rehabilitate the railroad bridge at milepost 7.09 on the Connecticut River Main Line.

The bridge, which spans the Connecticut River, is currently used by Amtrak (Vermonter and Valley Flyer services) and the Berkshire & Eastern Railroad (for freight service). A permanent speed restriction of 15 miles per hour has been in place on the bridge for many years due to its deteriorated condition.

Bridge 7.09 is a girder bridge consisting of two interconnected 10-span superstructure units, each designed to carry a single track. The bridge is 755 feet in length overall.

The bridge’s substructure (abutments and piers) were built in 1883 by the Connecticut River Railroad to support a 5-span iron truss bridge. The current superstructure—a riveted steel deck plate girder bridge—was constructed in 1921 by the Boston & Maine Railroad, in part to accommodate heavier locomotives.

In its early days, the bridge was equipped with a sidewalk for foot passengers, who paid a two-cent toll to cross.

Knowledge Corridor Positive Train Control project

In 2021 MassDOT initiated a project that would lead to the installation of a safety system known as Positive Train Control (PTC) on 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 Berkshire & Eastern Railroad.

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.

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

Milestones

1 The date for the opening of the station has slipped over time — from September 2025, to end of 2025. At this stage, in the absence of any official statement from CTDOT, the only reasonable assumption is that the station will open at some point in 2026.


September 14, 2022 | Governor Ned Lamont joined state and local officials to officially break ground for the Windsor Locks station 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, was expected to open in 2025.

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

The planned surface parking lots at the station are 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 people living in western Massachusetts 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.

Milestones

September 19, 2019 | The Connecticut Department of Transportation (CTDOT) hosted a public information meeting to present the project to the community.

Planning & Development | Jan 2025 – 2032 |  In Progress 
Final Design | 2032 – 2034 | Not Started
Construction | 2035 – 2038 | Not Started

The objective of this project to complete project planning and conceptual design for an improvement or replacement of the existing river crossing in the towns of Enfield and Windsor Locks, Connecticut. The project will evaluate track alignment alternatives and other potential design and construction solutions.

The current structure, which was built by the American Bridge Company in 1903, has a 35 mph passenger speed limit (10 mph freight) due to its condition.

This project is currently limited to completing the Project Planning phase in accordance with the FRA grant that was awarded for this project. Later phases of this project may include final design and a construction or rehabilitation project.

When fully implemented, construction would address the aging bridge structure, speed restriction, and a key bottleneck on the Springfield Line, enhancing the operability, capacity, and resiliency of the crossing. It will also improve trip time and address state of good repair issues, as well as increased growth with increased reliability when it completes double tracking of the entire segment.

Milestones

November 15, 2024 | The Federal Railroad Administration (FRA) awarded Amtrak up to $8 million in funding to support a review of options to replace the existing structure.
