The effort to provide passenger rail service between Western Massachusetts and Boston is getting another jolt of federal funding.

The Massachusetts Department of Transportation has secured a nearly $37 million grant from the Federal Railroad Administration that will help cover track, signal and infrastructure improvements at Springfield Union Station, Gov. Maura Healey’s office announced Tuesday.

“This money is critical to providing safe and efficient rail service between western, central and eastern Massachusetts and connecting our regional economies in Pittsfield, Springfield, Worcester and Boston,” U.S. Sen. Ed Markey said in a statement.

The investment “will increase rail capacity and reduce congestion, further paving the way for future West-East rail service and improving the North-South service”, Healey’s office said.

The new funding will help officials complete design efforts for the “Springfield Area Track Reconfiguration Project,” aimed at removing a “rail bottleneck” in western Massachusetts and western New England, Healey’s office said.

The project involves the modernization of railway and signaling systems, as well as the modernization of railway facilities and the rehabilitation of station platforms.

MassDOT won $108 in federal funding last year for the West-East Rail Project to improve rail corridors between Worcester and Springfield.

Healey’s office presented new ones Tuesday federal subsidies that will strengthen Massachusetts’ freight rail network, including an $8.9 million award that will be used in part to improve environmental and safety infrastructure along the Pioneer Valley Road Railroad, which runs from Holyoke to Westfield.

There’s also a $21.6 million grant for a tri-state rail safety and improvement project in New England, as well as a $19 million grant that Healey’s office said involves facility improvements and of the Providence and Worcester Railroad.
