Sent_en: 2zh Trains are not allowed to go out without these guides placed into the cars -LRB- the guides stop the loads from swaying from side to side in the cars -RRB- , important for safety with double stacked containers , but it seems that in this case the lack of employees forced the train to leave without them .
Sent_yy: 如果车辆上没有安装这些导轨（可防止货物在车里左右晃动），列车就不准驶离，这对双层集装箱的安全来说是非常重要的。但是看起来，由于缺乏员工的原因，只好迫使列车在未安装导轨的情况下开出去了。
