April 18 (Bloomberg) -- Amtrak, the U.S. national passenger railroad, plans to run one of its Acela trains today for a trip from New York to Washington and then from Washington to Boston, after suspending the high-speed service entirely on April 15 because of brake problems.

``Following disc brake inspections by federal safety officials and Amtrak this weekend, Amtrak cleared one Acela Express trainset for service,'' the company said in an e-mailed statement. ``The railroad will not speculate on the time it will take for a full resumption of service.''

The train was scheduled to depart New York for Washington at 8 a.m. local time for the No. 2109 service, the company said. The train would then be used for the No. 2168 service leaving Washington for Boston at 2 p.m.

Amtrak canceled all Acela departures after inspectors found cracks in 300 of 1,440 brake rotors. The 20 Acela trains, which travel as fast as 150 miles (241 kilometers) per hour, provide a fifth of Amtrak's service in the Northeast and are the company's highest-priced service.

Amtrak had said the trains may be out of operation for as long as two months while repairs are made. The trains are made jointly by Canada's Bombardier Inc. and France's Alstom SA.

During the suspension, Amtrak said it will increase Metroliner trains between New York and Washington and Regional trains between Boston and Washington. New Jersey Transit will operate an Amtrak Clocker service leaving New York at 5:15 p.m. for Trenton, Amtrak said.
