Phase I

Line S2 (simplified Chinese: S2线; traditional Chinese: S2線; pinyin: S Èr Xiàn) is the first line of the Beijing Suburban Railway to begin operation. Opened on August 6 of 2008, it runs from the Beijing North Railway Station, near Xizhimen, to Badaling in Yanqing County, following the old Beijing-Zhangjiakou Railway, and provides faster, more frequent and convenient service than preexisting trains. The line is currently 82 kilometres (51 mi) in length with six stations:

Station Name English	Station Name Hanzi	Transfer	Location
Beijing North Railway Station	北京北站		Xicheng
Qinghuayuan	清华园		Haidian
Qinghe	清河
Changping	昌平		Changping
Nankou	南口
Badaling	八达岭		Yanqing County
Yanqing (Nancaiyuan)	延庆（南菜园）

Trains can reach maximum speed of 160 kilometres per hour (99 mph). A trip from the north station to the Badaling Great Wall takes about 1 hour and 22 min. Seven other stations including Dongyuan (东园) are being renovated for this line. There are regular departures throughout the day from Beijing North, with an average of 1 train per hour during operating hours. A one-way ticket costs ¥6. Tickets can be purchased from ticket offices of stations along route on the day of travel only. The Beijing Transit card is accepted on this route. Train identification numbers are prefixed with the letter 'S'. The line currently primarily serves tourists traveling to the Great Wall of China at Badaling.

The S2 line uses the NDJ3 locomotive in an 8-car push-pull configuration. Accommodation comes in 'soft-seat' class only with a 2+2 (first class) or 3+2 (second class) layout. The seats were reversible, but that feature has been removed. Between Nankou and Badaling stations, the train makes a reversal at a switch-back junction. Although all stations are equipped with high-level platforms, trains are equipped with retractable steps and can also serve low-level platforms. On-board facilities include air-conditioning/heating, toilets, hot-water dispensers and a cafe-bar selling tea, coffee, soft drinks, beer and snacks. Smoking is not permitted on the train.
