The Acela Express...is Amtrak's high-speed rail service along the Northeast Corridor (NEC) in the Northeast United States between Washington, D.C., and Boston via Baltimore, Philadelphia, and New York City.
Acela Express trains are the only true high-speed trainsets in North America; the highest speed they attain is 150 mph (240 km/h), though their average is less than half that speed. Wikipedia
I was on the Clinton Train Station platform when this blew by. There was an announcement to step back behind the yellow line. It is good that I did, as the there was a strong gust of wind as it went by. :)
