列车相撞事故，一辆运行中的列车撞上了另外一列停靠在站点上的列车，司机试图手动
紧急制动但未成功。幸运的是，事故发生区段正在进行测试，列车也未载客，只有列车
司机受伤，但直到两天后，两辆相撞列车在被吊车分开。
据悉，圣保罗地铁15号线是世界上第一条使用庞巴迪Innovia 300列车的跨座式单轨线
路，中国芜湖地铁1/2号线也使用了这种车型，另外还有沙特阿拉伯、泰国的线路。
圣保罗地铁15号线全长27公里，车站18座，目前已开通运营7.6公里、车站6座，日客运
量约4.5万人次，是运量仅次于中国重庆的单轨线路。
该线路采用全自动无人驾驶的CBTC系统，理论上能在紧急情况下提醒司机手动启动紧急
制动，但事故时列车司机并未来得及操作。
另外，由于单轨列车没有驾驶室，司机必须用钥匙打开防护罩才能启动制动器，耽误了
操作时间。
从目前的情况看，事故原因应该出自信号系统或调度指挥错误。
