Amtrak plans to test high-speed travel this week, running trains along the Northeast Corridor at 165 mph as the precursor of higher speed service.

The tests start Monday and will occur in Maryland on Tuesday night, running back and forth for 21.3 miles between Perryville and Wilmington, Del., for six hours at some point after 10 p.m. and into early Wednesday morning, said Amtrak spokesman Cliff Cole. Other test areas are slated for New Jersey, Rhode Island and Massachusetts.
