"BWRR has identified its preferred configuration; Build Alternative J, BARC West TMF, and Cherry Hill as the north terminus station (Build Alternatives J-03). BWRR favors this alternative for its shorter construction, ability to avoid and mitigate impacts, and lower construction and operating costs. BWRR believes Build Alternative J-03 will be the least impact and lowest cost to construct, operate, and maintain while also providing the earliest start to revenue service.
The Build Alternatives J alignments are a combination of tunnel sections and viaduct. Build Alternative J alignments extend 33 to 36 miles end-to-end, depending upon which Baltimore Station option is selected, and would average approximately 75 percent (or
25 to 27 miles) tunnel and 25 percent (or 8 to 9 miles) viaduct.
Build Alternatives J (BWP East) includes a newly constructed independent station in Washington, D.C. (Mount Vernon Square East). The proposed alignment would be in a tunnel (see Figure 3.4-1) under Washington, D.C. from the southern terminus near Mount Vernon
Square to east of the Capital Beltway (I-95/I-495). In this section, Build Alternatives J would be in a deep tunnel, typically 80 feet to 260 feet deep, with an optimum depth of approximately 320 feet and minimum depth equivalent to one tunnel diameter or approximately 50 feet.
After crossing under the Capital Beltway (I-95/I-495), the guideway would transition from tunnel to a viaduct, on the east side of the BWP between the National Aeronautics and Space Administration (NASA) Goddard Space Flight Center (GSFC) overpass and Beaver Dam Road. A portal structure would transition the guideway between tunnel and viaduct. In Build Alternatives J alignments, the viaduct would be an optimum of 131 feet above ground level and 125 feet above the elevation of the northbound travel lanes of the BWP. Build Alternatives J would generally follow the east side of the BWP travel lanes on viaduct through Federal lands including the BWP, the U.S. Department of Agriculture’s Beltsville Agricultural Research Center (BARC), Patuxent Research Refuge (PRR), and Fort George G. Meade, and run adjacent to Federal facilities (U.S. Secret Service [USSS] and National Security Agency [NSA]) before returning to a tunnel on Fort George G. Meade. Build Alternatives J would continue north in tunnel toward a newly constructed underground BWI Marshall Airport Station.
North of the airport, Build Alternatives J would continue in a tunnel to Baltimore, MD. The northern terminus would be a newly constructed passenger station.
The BARC West TMF would be on the portion of BARC property that is on the west side of the BWP. The facility would be on forested land between Powder Mill Road and Odell Road. Because the site slopes downward toward the northwest and Odell Road, the Project Sponsor would provide up to 56 feet of fill to raise the northwestern portion of the site to a level grade with the rest of the TMF site. The fill would be supported by perimeter retaining walls.

75% subway and 25% elevated guideway is not half elevated - half subway. The Baltimore station will not be under Camden Yards nor the convention center. The DC station will not be under Union Station. The only locations that this maglev will be visible or heard to non riders will be near the Cherry Hill Station, the TMF at BARC West, and along federally owned property at BARC, Fort Mead, and the Wildlife Refuge.
Additionally, this EIS also looked at what improvements are and will be done to Amtrak's NEC.
"FRA’s 2017 Record of Decision for the NEC FUTURE program identifies service and performance objectives to improve rail service on the NEC. To meet these service and performance objectives, FRA recommended the following improvements within theProject Study Area that would allow for an increased number of daily trips and shorter travel times on both Amtrak and MARC commuter service:
• Chokepoint relief projects at three locations:
– Reconstruct New Carrollton Station to have four platform tracks, thus permitting express and local trains serving the station to operate on separate tracks
– Reconstruct Odenton Station, resulting in island platforms that allow Amtrak trains to stop at station on express tracks
– Reconstruct BWI Marshall Airport Station with a new platform and improvements to existing platforms to accommodate upgrades to four tracks through the station (this is a related project to NEC FUTURE)
• New Track Capacity
– Expand track capacity from New Carrollton to Halethorpe to a consistent four tracks, from the current two/three track configuration
– Provide systems upgrade to high density signaling to meet service and performance objectives
In addition to the NEC FUTURE program, there are related projects on the NEC that are moving forward separately, but would have an impact on intercity rail in the Project Study Area:
• Replacement/Rehabilitation of the Baltimore and Potomac (B&P) Tunnel – The B&P Tunnel runs under West Baltimore and provides access to Baltimore Penn Station from the west. Planning for the replacement or rehabilitation of the tunnel is moving forward as a project separate from the NEC FUTURE program but would have a significant impact on MARC and Amtrak service in the Project Study Area by allowing for higher speeds/shorter travel times.
• BWI Marshall Airport Rail Station Improvements and Fourth Track Project - The project includes providing a new platform, improvements to the current station, with possible multi-level transit-oriented development and addition of nine miles of the fourth track along the NEC generally between Odenton Station and Halethorpe Station.
Each of these improvements to the NEC would allow for capacity expansion, more frequent service on both MARC and Amtrak within the Project Study Area as well as shorter travel times between Washington, D.C. and Baltimore, MD."
