上周三早上，连接西南郊区和中心市区的燕房线--北京第一条无人驾驶地铁线路--开始第一次试运行。

　　It is also the capital city's first subway line that is fully automatic, and fully equipped with domestic technology. The line is expected to officially open to citizens at the end of next year.

　　这也是首都第一条全自动、全装备国产技术的地铁线路。该地铁线路预计将于明年年底对市民正式开放。

　　The difference between the driverless subway line and the ordinary line is that the driverless technology allows the subway train to automatically complete all running procedures, including traveling, dormancy, awakening, opening and closing train doors, as well as returning, without any operations by drivers.

　　无人驾驶地铁线路和普通线路的区别是，无人驾驶技术让地铁列车不需要驾驶员任何操作、自动完成所有的行驶程序，包括行驶、停车、再启动、打开和关闭车门、以及返回等。

　　在紧急情况下，乘坐地铁列车的乘客可以通过安装在每节车厢里的无线对讲设备与控制中心联系。

　　The camera in the carriage can automatically transmit images back to the control center.

　　车内的摄像头可以自动将图像传回控制中心。

　　A "black box" has been installed at the bottom of each train and it can activate emergency braking within 1.4 seconds if obstacles that might affect the running of the train have been detected.

　　每列列车底部都安装了一个“黑匣子”，如果检测到可能影响列车运行的障碍物，可以在1.4秒内启动紧急制动。
