Will Northeast Maglev ever happen?

About 70 percent of the line will be in underground tunnels and Northeast Maglev aims to open the first section, a 65-kilometer span between Washington and Baltimore, by 2035. Former New York Gov. George Pataki, a member of the advisory board of Northeast Maglev, described the project as "real" and "practical."



As of early 2026, the future of the Northeast Maglev (SCMAGLEV) project is highly uncertain following a major setback in August 2025. The U.S. Federal Railroad Administration (FRA) officially halted the environmental review of the proposed high-speed line between Washington, D.C. and Baltimore, citing "significant and unresolvable impacts" to federal property and potential cost overruns. While the private developers, Northeast Maglev LLC, continue to advocate for the project—promising a 15-minute trip to Baltimore and a 60-minute trip to New York City—the loss of federal backing has effectively placed the plan on indefinite hold. Supporters argue it is a necessary "leapfrog" technology to solve Northeast Corridor gridlock, but critics point to the massive $10+ billion price tag for the first leg alone and the competition from Amtrak’s Acela upgrades. Without a significant shift in political will or a massive new private funding surge, the dream of 311 mph maglev travel in the U.S. remains stuck on the drawing board.

1. High costs: The initial construction costs for maglev train infrastructure are significantly higher compared to traditional rail systems. This includes building guideways and installing magnetic levitation technology. The high costs have been a major deterrent for many countries and transit authorities.

MORE DETAILS

The high cost of maglev systems results from the need for a stand-alone guideway construction featuring active magnetic coils embedded directly into the guideway or on the vehicle and, in the case of the Japanese design, the addition of very low temperature liquid cooled superconducting magnets.

Disadvantages of Maglev Trains Complications resulting in accidents will usually lead to high human fatalities. Maglev trains are much more expensive to construct than conventional trains because of the high number of superconducting electromagnets and permanent magnets required, which are usually very costly.

CLIMATEWIRE | The first U.S.-made high-speed bullet trains will start running as early as 2024 between Boston, New York and Washington, with the promise of cutting transportation emissions by attracting new rail passengers who now drive or fly.

MORE DETAILS

Maglev trains are “driven” by the powered guideway. Any two trains traveling the same route cannot catch up and crash into one another because they're all being powered to move at the same speed. Similarly, traditional train derailments that occur because of cornering too quickly can't happen with Maglev.

Tracks: None of the nation's rail lines are built for trains to run 200 mph. Amtrak's Northeast Corridor — the busiest intercity U.S. passenger route by a wide margin — is filled with sharp curves, bottlenecks, decaying tunnels, bridges and overhead power lines that slow down trains.

The proposed Pennsylvania High-Speed Maglev project is an approximately 54-mile maglev line connecting Pittsburgh International Airport, Downtown Pittsburgh and Monroeville and Greensburg, Pennsylvania, with multi-modal stations at these locations.

American railways were also built on a wider gauge (the distance between the rails), which allows for larger and heavier trains. As a result, American freight railways are much more efficient than their European counterparts, carrying almost three times as much cargo per mile of track.

In addition, the tracks, signals, rail cars and software made in the U.S. are costlier than imports, largely because the government has not funded rail the way European and Asian countries have, experts say.

Maglev trains do not create direct pollution emissions and are always quieter in comparison to traditional systems when operating at the same speeds.

Even with regard to earthquakes, maglev trains are considered to be very secure rapid transit systems.

One of the most expensive parts of building new rail lines these days is securing land along a relatively straight path (you can't run trains at high speeds along too sharp a curve). The U.S. has strong property rights which makes securing land exceedingly expensive.

“The project, as currently planned, would cost too much and take too long,” Newsom said as he took office. “There's been too little oversight and not enough transparency. Right now, there simply isn't a path to get from Sacramento to San Diego, let alone from San Francisco to L.A. I wish there were.”

China initially relied on high-speed technology imported from Europe and Japan to establish its network. Global rail engineering giants such as Bombardier, Alstom and Mitsubishi were understandably keen to co-operate, given the potential size of the new market and China's ambitious plans.

Maglev trains require very straight and level tracks to maintain high speeds. This necessitates extensive viaducts and tunneling, making construction costly.

The Superconducting Maglev is equipped with a braking system capable of safely stopping a train traveling at 311mph. Regenerative braking is normally used for deceleration, but if it becomes unavailable, the Superconducting maglev also has wheel disc brakes and aerodynamic brakes.
