Such trains are only found on lines 6 and 7.
The trains are capable of reaching the speed of 100 km/h (62 mph). Stations to the east of the 3rd Ring Road to Tongzhou are more widely spaced, the furthest being 4 km (2.5 mi) apart. Line 6 also has the deepest station in the network, Dongsi station, which is 34 metres (112 ft) underground. The line is the first line to 1500 V overhead catenary as opposed to 750 V third rail used on all earlier lines. Some of the station arrangements were the first of their kind in Beijing. Beijing's first split platform station, Nanluoguxiang station, and stations equipped with passing tracks, opened on Line 6.
