JR Central plans to use the L0 series on the Chūō Shinkansen railway line between Tokyo and Osaka, which is under construction.

Mitsubishi Heavy Industries and Nippon Sharyo, a subsidiary of JR Central, are building fourteen pre-production vehicles.

[6] The train does not require a driver, but has a camera at the front of both end cars in order to allow for remote operation, in case the automated systems fail.

However, after receiving a ¥3 trillion ($28 billion) loan from the Japanese government, JR Central moved the project forward.

[14] A route from Washington, D.C. to Baltimore, eventually extending to New York City has received support in the United States.

JR Central chairman Yoshiyuki Kasai spoke with U.S. President Barack Obama about the L0 series during Prime Minister Shinzo Abe's 28 April 2015 visit.

In August 2017, development partner Mitsubishi announced that talks had "stalled" because of "a lack of clarity on the Trump administration's stance on high-speed rail".

[15][16] In March 2019, Northeast Maglev project director David Henley said in an interview that they planned to have a Record of Decision for the D.C.–Baltimore section by August 2020.

[10] The first five-car train began test-running at the 42.8 km (26.6 mi) Yamanashi Maglev Test Line in June 2013, following completion of extension and upgrade work at the facility, earlier than the originally scheduled September date.

Before the new series train was introduced, on-board power was provided by a small gas turbine generator in each end car.

With 49 JR Central employees on board, the train sustained the speed for 10.8 seconds, travelling 1.8 kilometers (1.1 mi) during that time.
