This is of course, an exaggeration. No subway trains in the world operate literally "back to back"- it is unsafe. There is always a minimum braking distance between trains that is maintained- which can be as close as a few hundred meters (or less), depending on operating speed. To the average subway rider, this "to the limit" operation gives an image of train chasing train.

Precisely. However, automated systems do have somewhat of an ability to do that. Vancouver's SkyTrain system does that, but you really only see this at the line terminus, where trains head into the station, unload, continue to end of track, then goes back into the station changing tracks to another platform, then loads again. But you wouldn't see trains constantly "back-to-back" with one another, even with an automated system, because it can lead to many system backlogs: if one train is held at a station longer than expected, than the trains behind it are forced to wait until that train leaves the station before they can enter.

in shanghai rush hours, i have caught [email protected]#! numbers of metros that stops before it enters a stop, waiting for the previous metro to leave the station ahaha, does that count as the shortest interval in the world XD

also there are times when you wait 10minutes for a metro in the rush hours and when it finally comes everyone rushes on before you. just when you get angry, the second train comes 20 seconds later

That depends on what line you ride. Line 1 and 2 are pretty old and designed quite poorly. Line 13 is the worst, cramped trains and slow service. Lines 5,8,and 10 are world class subway systems and all have beautiful trains and stations. Transferring from line 10 to line 1 at Guo mao is like going in a time machine.

That happens during rush-hour in Vancouver as well. The LIM trains probably accelerate slightly faster than Shanghai, however, due to LIM propulsion and weight... so probably a slightly shorter interval (headway). (But really, we're talking seconds here). I dont' think I've waited 10 minutes for a train, though... unless there's a serious problem.

Not sure what Shanghai uses, but SkyTrain here uses the Moving block system... so the faster a train is traveling the more track is blocked off in front and behind it. Two blocks are never allowed to be on the same track.

When it comes to intervals between trains, maximum sustainable interval time is more important than occasional or theoretical time.

Moscow has the most used. For some reason the 12,000,000 / day is in my head, but I'm too lazy to confirm that. I don't think it's the biggest system but it probably could be considered the most beautiful.

According to the latest annual figures (2008), Tokyo has the highest ridership per annum: Wikipedia.
Re-calculated to the number of passengers per day, Moscow averages out on a little more than 7 million riders. Still impressive, but not quite near the 12 million in your head (though that could have been the peak usage for a particular, very busy day)

i dont know how metro in shanghai works, but i know it is in fact the delay of the first train which makes the two trains coming in the station simutaneously

for example the train should come in a 5minute interval, but one delays by 4 minutes however the next train is still on schedule

Beijing's new subway line to open Monday

2009-09-25

A new subway line is to open in Beijing next Monday, three days ahead of the National Day of the People's Republic of China on Oct 1, local authorities said Friday.

The No 4 subway line, which runs south to north through the heart of the city, is 28.2 km long with 24 stations. It is expected to transport more than 400,000 passengers a day.

The subway project had passed inspections by local authorities in regard to construction, urban planning, quality supervision, fire prevention and environmental protection, and the new line would begin operating on Sept 28, a spokesman with the Beijing Municipal Commission of Housing and Urban-rural Development said.

Currently, Beijing has eight subway lines covering 200 kilometers.

The city government plans to build more subway lines, increasing the total length of the city's subway system to 300 km by 2010 and 560 km by 2015.

New Subway line to accelerate Beijing life

2009-09-27

A new subway line will start operation in Beijing just before China's National Day on October 1. But the exact date remains unannounced.

With a total length of 28.2 kilometers, the Subway Line 4 runs through the city from the northwest to the south.

It will help relieve the pressure of old tube lines by offering an alternative access point to some of the most crowded stations such as XIDAN, which is the center of many shopping malls and is also a rising financial centre.


The ceiling of XIDAN Station is designed to represent copper coins

The new line will also for the first time service many other key places of the city where traffic is not so efficient. For example, it will shuttle people to Beijing's IT centre ZHONGGUANCUN, which is known for its enduring traffic jams. A subway station will also be located inside the Beijing South Railway Station, allowing riders to take the tube right after getting off the train.

Apart from the convenience brought by Line 4, each station also provides a pleasant and diverse visual experience to travel weary commuters.


The Beijing Zoo Station is decorated with pandas.


This station's ceiling is full of abstract balloons and its walls are covered in gorgeous cartoon frescos. The Beijing Zoo station is targeted towards childrens' taste as much as the zoo itself.

In comparison to this liveliness, the area of YUANMINGYUAN Park is designed to show the gravity of history. The relief sculpture depicts the relics in the park, with the years of when it was constructed, ruined, and burnt.

The peeling stone may look a bit abrupt in this clear and modern environment, but the contrast seems to remind us that no matter how fast-paced, how fancy our life is now, roots should never be forgotten.

I love the Beijing Subway documentary video in China Daily. Is there a way to download it? Or another download link. I try with Firefox addon UnPlug, but it didn't work.

Line 4 Opened (28.2 km)



BEIJING: The second south-to-north subway line in China's capital started trial operation on Monday, according to municipal transport authorities.

An opening ceremony was held Monday morning for the No. 4 metro line in Beijing, which traverses 28.2 kilometers from the Gongyixi Bridge at the southern section of the city's fourth ring-road to the Summer Palace and the Old Summer Palace.

The project cost 15.38 billion yuan (US$2.25 billion) to build, with Beijing Government taking 70 percent of the stake and the MTR Corporation from Hong Kong holding the remaining 30 percent.

This was the first time private capital was ushered in for construction of a subway line on the Chinese mainland.

It takes 48 minutes to run through all the 24 stations on the No. 4 metro line, and the distance is usually a two-hour drive for a car.

It is estimated that the new subway line will accommodate 400,000 passengers a day on average.

According to the local transport authorities, No. 4 subway is the first metro line on the mainland to adopt the state-of-the-art shock-absorption and noise-reduction technology. The technology, which enables a subway train running "quietly", will be introduced to construction of new metro lines in Beijing, the authorities said.

Li Xiaosong, spokesperson for the municipal transport authorities, said from now to 2015, Beijing will spend 270 billion yuan to improve public transport infrastructures, including subway lines.
