Amtrak posted this press release on its Media website on 1/22/21:
WASHINGTON – Amtrak is transforming Northeast Corridor train travel by enhancing the customer experience, both in stations and on board trains. As part of this effort, Amtrak is currently accepting Letters of Interest from interested contractors until Feb. 15, 2021, for construction associated work at New Carrollton Station in Maryland. The project involves work within the existing station and the construction of a side platform, and will be closely coordinated with Amtrak for minimal impacts to service.From the document at the "Letters of Interest" link:
This infrastructure work is underway in preparation for the introduction of the new Acela fleet scheduled to begin entering service in 2021. The project is necessary to support higher frequency Acela service by expanding the routing options available for high-speed trains in the busy triple-track territory between Washington, D.C. and Baltimore, which is also heavily utilized by commuter trains.
Constructed in 1983 as an intermodal facility, the New Carrollton station serves Amtrak and Maryland Area Regional Commuter (MARC) trains, Washington Metrorail, Metro buses, MTA buses and county transit, as well as many commuting drivers who connect to transit and Amtrak. The New Carrollton Station is served daily by Amtrak’s Acela, Northeast Regional, Palmetto and Vermonter trains. New Carrollton Staton is located on the Northeast Corridor (NEC), one of the busiest, most complex, and economically vital transportation systems in the world connecting eight states and the District of Columbia.
In an effort to make Amtrak the smarter way to travel, we are also upgrading our infrastructure and modernization efforts and improving track capacity and ride quality all along the Northeast Corridor. The New Carrollton Station project also complements other significant station expansion investments at New York Penn Station; the opening of the new Moynihan Train Hall in New York; and further development of stations in Washington, D.C., Baltimore and Philadelphia.
This project involves selective demotion within the existing station and the construction of a side platform on the east side of Track 1 at the New Carrollton Rail Station. There is an existing high-level platform positioned between Track 2 and Track 3 therefore, all work shall be coordinated with train and passenger service.
The platform for Track No 1 will be a newly constructed platform south-east of all track alignments. The construction of this platform will require construction modifications to the existing back of house space, existing concourse, and installation of new passenger vertical circulation elements between the existing station concourse and the new platform(elevator, two new stair cases and two escalators). The new platform will be approximately 1050 feet long and its canopy will be approximately 700 feet long.
