Rail passengers in the nation's Northeast Corridor can travel aboard Amtrak's NextGen Acela high-speed rail service that launched on Wednesday morning.

Amtrak’s long-awaited NextGen Acela trains debut this week with faster top speeds, upgraded seating, improved accessibility and modern amenities.

Amtrak is introducing five of its 28 planned new NextGen Acela trains on Thursday, signaling the next step of America's attempt at high-speed rail.

The NextGen high-speed trains feel more like those in China, Japan or France. But topping out at 160 m.p.h., they’re still relatively slow.
