Line 15 has a total length of 41.4 kilometres across northern Beijing from Xiyuan in the west, to Hedong in the east, although various plans were revised repeatedly.
Phase I covers the eastern half from Qinghuadongluxikou to Fengbo, but there is still uncertainty whether the westward extension will reach Xiyuan, or whether it will turn south. Currently, the journey on a train from Fengbo to Qinghuadongluxikou takes about 60 minutes.
Line 15 tunnels are up to 38 metres underground, making them the deepest in Beijing’s subway system.
One of the outstanding themes on Line 15 is its lighting, with some stations having beautiful displays along the platform ceilings.
Another repeating theme on Line 15 is the use of the ‘Chinese Red Style’. Pure red columns and red brackets can be found at many stations and in those stations which are underground, these contrast with the white or light grey ceilings and floors to great effect.
The most striking station in this respect is Shunyi, which has a large red octagonal caisson in its ceiling.
