Amtrakâs Acela Express is currently the fastest train in the US, capable of a maximum speed of 150 mph (241 km/h) â although it typically travels at about half that speed.

California still wants 220-m.p.h. trains for its planned high-speed line between Los Angeles and San Francisco. Amtrak's Acela Express trains now travel up to 150 miles per hour on a short stretch in New England, but the top speed between New York and Washington is 135 miles an hour.he same month, Amtrak published proposed performance requirements that called for a maximum operating speed of 220 miles per hour, with a maximum test speed of 225 mp.h. But when Amtrak issued draft specifications for the new trains on Nov. 19, gone were the requirements for 220 m.p.h service on the Northeast Corridor.
