Walking Beijing’s LONGEST subway transfers 

Thoroughly satisfying video. Well done!

In ancient times Line 13 was in a different system from Lines 1/2 and to transfer at Xizhimen one had to exit the station. Later the section outside the station was eradicated but through the creation of a restricted passageway on the surface connecting the two stations, and it is rumored to be over a kilometer of walking that usually takes half an hour. It is also speculated that some transfers in the Beijing subway system are deliberately prolonged in order to trap more passengers in the passageways and feed the platforms more smoothly so that the platforms wouldn't become dangerously overcrowded.

I think it took longer at Dongzhimen when you walked from Line 2 to Line 13 because you were walking to the Line 13 boarding platform, and the arrival platform is closer to Line 2

The longest loop metro line record was just broke by Moscow line 11😄back to transfers stations, BJ's city road network is a very rectangle grid, 90 degree intersections everywhere, metro network design naturally matches this shape, the primary consideration is to move ppl cross surburban and center in the shortest way, so north-south and east-west straight along existing traffic corridors. The convienience of transfer is not priority at that time because the network at that time doesn't need much transfers. As the urban grows & changes fast, some early metro designs have outdated even before being built, the design has to change to accomodate new urban developments. Some transfer stations were not orginally designed to host more than 1 line, then later when plan changes it has to work around using long winding passages to make it work. Later network plan becomes more stable, so newer lines generally have better connection because the transfer passage is already considered with other factors like location/track/platform alignment in master plan. Hong Kong metro system is a very different design compared to BJ. HKMTR uses mostly parallel transfers, which is you transfer to another line by simply going to another side of the platform. HK's urban landscape is very scatterred because of its mountainous terrain, you have isolated urban areas here and there, and a lot of them are strip shape because you have to develop along the only flat space between hills and on seashore. So HKMTR lines can naturally share same corridor at population centers, then divert to different directions. When you have two lines running parallel for a section, it is possible to make parrallel transfer. It requires two tunnels for each line, one on top and one beneath it, and sometimes tunnels need to do a up-down swap between stations, so it is more expensive and difficult engineering.

You sound like an American. Well, I was also impressed by NY subway 35 years ago when coming from China.

The London Underground has some short and long transfers too. In the short category changing to the Piccadilly line to go to either Uxbridge or Heathrow Terminal 5 from the District line is no distance at all, it's the opposite platform. Some long walks Northern to the Jubilee line at London Bridge (5 minute walk) and Victoria line to the Northern Line at Goodge Street (another 5 minute walk)

In Mexico there is a Subway transfer which is 880 m long

You know, when I moved to Beijing, there were only two subway lines. I still remember the scene when Line 13 opened. I have been away from Beijing for three years. After watching your video, I found many new changes! Thank you!

Sanyuanqiao is having an extra line added to make 3.

you need those shoes with the wheels in them

Xizhimen, Qianmen, and Shilihe are honorable mentions, too

Hello, brother. Can I ask what application can be used for Google maps? Thanks

You can only want to remove faults .

I was expecting you to do the Xizhimen transfer haha. I heard its dreadful

Which app you use in the video? 😄

Do you have such a subway in your country.
