1、The Tier IIstandards only impact the Amtrak Acela Service on the Northeast Corridor because Acela is currently the only Tier II application operating in the United States.
2、The Acela pulled into Penn Station a few minutes late, arriving at 12:55 p. m.
3、With some exceptions on Amtrak's Acela and North East corridor tracks, level crossings are attuned to limits of 50mph for freight and 80mph for passenger trains.
4、Although the Acela shares tracks with slower-moving passenger and freight trains, "sharing rails between high-speed and freight won't work" if fast trains are introduced and traffic is increased.
5、Acela高速列車每天多班，往返票價最低元區域列車稍慢一些，往返票價最低元
6、儘管Acela是與低速客運列車、貨運列車共享軌道，一旦高速列車引進、運輸量增加，“高鐵與貨車共享軌道是行不通的。”
