北京计划开始试运行夜班地铁服务，旨在帮助乘当日末班高铁抵京的旅客到达其最终目的地。
Beijing plans to start a trial operation of late-night subway services, aimed at helping people arriving on the last high-speed trains of the day get to their final destinations.
北京市交通委主任周正宇称，贯通南北、经停北京南站的4号线将开始试点夜间服务。
Line 4, the north-south line that serves Beijing South Railway Station, will begin a trial of late-night services, according to Zhou Zhengyu, head of the Beijing Municipal Commission of Transport.
目前，4号线末班车在北京南站的离站时间为晚上11时15分。
At present, the last subway train of Line 4 leaves the railway station at 11:15 pm.
周正宇称，今后晚于这一时间到站的旅客将可乘坐地铁前往北京其他地方。
Travelers arriving at the station later than that will be able to take the subway to other parts of the city, Zhou said.
北京地铁总长度目前达到了554千米。据周正宇表示，该市计划在2020年将总路程增加到900千米，这就意味着北京地铁系统的长度将会比纽约和伦敦加起来还要长。
Beijing's subway lines total 554 km. Zhou said the city plans to increase the distance to 900 km by 2020, which would mean that Beijing's subway system would be longer than New York City's and London's combined.
同时，在北京首都国际机场乘机的旅客将可在东直门交通枢纽托运行李，搭乘地铁前往机场。
Meanwhile, those taking flights from Beijing Capital International Airport will be able to check in their luggage at the Dongzhimen transportation hub, where passengers can take the subway to the airport.
北京一家贸易公司的通勤族韩佳媛表示，这对她来说会便捷得多，因为她总是随身携带着沉重的行李。
Han Jiayuan, a frequent commuter at a trading company in Beijing, said it will be much easier for her because she always has to carry heavy luggage.
