Amtrak will begin rolling out NextGen Acela trains on August 28, launching five trainsets that will operate on the Northeast Corridor between Boston and Washington, D.C. The new trains offer up to 160 mph top speeds, more seats per departure and upgraded onboard amenities, according to Amtrak.

After several years of delays, Amtrak is expected to debut its new, redesigned Acela high-speed trains in Philadelphia later this month, writes Mike D’Onofrio
