A few years ago, somebody (who worked in NYC MTA) told me that, unlike China and Europe, there was no regular check up of trains in USA due to no money. The train is the least safe transportation means in USA. I do not know how it is now. Good luck to everybody who takes train.
据美国NBC新闻报道，当地时间12日下午，美国华盛顿一列地铁在阿灵顿国家公墓附近脱轨，造成200到300名乘客滞留数小时。尚无人员伤亡的报告。
在消防队员帮助下，乘客分批撤离，他们沿着黑暗的隧道，行走600多米后，从阿灵顿国家公墓站出口离开。
有乘客发布的现场视频显示，脱轨后的车厢内漆黑一片，地面上亮起绿色应急灯，不少人低头看手机。
