Acela tops out at 150-160 mph (240 km/h-260 km/h) which is is above the 200 km/h bar for it to be considered HSR. Unfortunately, the route it runs on has several speed limits below even 100 km/h due to bridges and tunnels beyond the design life, so it's hard to call it HSR when it can't actually hit those advertised speeds.
