Amtrak suspended operation of the Acela
Express trains on Friday, when cracks were found in the brake rotor
spokes. One of the trains ran the route between Boston and
Washington, D.C., on Monday but has now been stopped, as well.
While Amtrak works out how and whether to fix the Acela trains,
Metroliner and regional trains are running most of the schedule
between Washington and New York, and regional trains are operating
between New York and Boston.
