Is Fangshan Line out of service?

From July 3, 2023 to August 3, 2023, Fangshan Line of Beijing Metro was temporarily suspended.

Fangshan Line of Beijing Metro, also known as "Beijing Metro Line 25", is the tenth subway line in China and Beijing. Fangshan Line of Beijing Metro runs northeast-southwest, starting from Dongkou South Station in the north and reaching Yancun East Station in the west, passing through Fengtai District and Fangshan District. At 20 o'clock on July 29, Mentougou District of Beijing suffered from continuous heavy rainfall. On July 3 1 day, according to the official news of the airport bus, due to heavy rain, there was serious water accumulation along Fangshan Line, and the operating vehicles could not pass normally, so measures were taken to stop.

When encountering heavy rainfall, there may be problems such as ground seepage, sewage flooding the subway workshop, and damage to the track catenary, which will affect the traffic order of the city. The suspension of Fangshan line is conducive to ensuring the safety of passengers.

The advantages of the subway are as follows:

1, saving land

The value of urban land in general metropolis is high. Building the railway underground can save ground space and make the ground land be used for other purposes.

Step 2 reduce interference

Because the running route of the subway does not overlap or cross other traffic systems (such as ground roads), there is less traffic interference and a lot of commuting time can be saved.

3. Heavy traffic volume

The transportation capacity of subway is 7~ 10 times that of ground bus, which is incomparable by any urban means of transportation.

Step 4 be quick

Subway trains go at full speed in underground tunnels, with a top speed of 80km/h, which can exceed100km, and some even reach120km.

Step 5 reduce pollution

Ordinary cars use gasoline or petroleum as energy, and subways use electric energy, which does not emit tail gas and pollute the environment.
