http://www.seattletimes.com/seattle-news/transportation/speed-human-error-blamed-for-amtrak-derail ... Based on pictures, Elliott figures the train probably slowed to 10 or 20 mph by the time the switch-like device opened the trackway, so the locomotive rolled into the gravel alongside. 这么说还真是个脱轨岔子
BNSF has installed new-generation positive train-control systems, which use satellite technology to prevent collisions and missed signals. Amtrak is scheduled to install this technology in its locomotives by the end of 2018. 那条轨道是BNSF的,他们已经给自己的机车装了带卫星定位的防碰撞和冒进的设备,可能功能上类似于国内LKJ?
结果美铁的这趟车的机车要装但当时没装
