WASHINGTON - Amtrak's Acela Express service has been cancelled through Wednesday April 20. Passengers with reservations on these cancelled trains will be accommodated on other regular Amtrak service. As additional equipment becomes available, extra frequencies will be added in place of the cancelled trains.

Acela passengers should call 1-800-USA-RAIL to adjust their existing reservations. Passengers who are accommodated on other Amtrak service will be refunded the difference of the two ticket prices. Passengers who board an Amtrak train holding an Acela ticket will need to keep their receipts in order to later receive their price adjustment. If passengers wish to cancel their reservations, full refunds will be given.

During routine inspections of Amtrak's high-speed Acela Express trains Thursday night, cracks were discovered in the brake rotors of the trains. No brake failures or other safety problems have occurred and these cancellations are as a precautionary measure.

All other Amtrak service will operate as scheduled, including Regional, Clocker, Keystone, Empire and long-distance train service. Metroliner service will also operate.

Acela Express train service will resume when Amtrak is confident the brake problem is resolved and the trains are safe to operate.
