Agree. Increasing capacity is the solution. But there are some engineering challenges aside from money issues to increase capacity. Say for example, increasing the number of train cars in line 1, would require lengthening the underground stations. This will most likely result to temporary closure of portions or maybe whole line 1. This will certainly a traffic nightmare in central Beijing once line 1 will be closed.

The most feasible way to implement line 1 upgrade is to wait until line 3 will be completed. Line 3 in the current plan, is in between line 1 and line 6 in the west portion, and parallel to line 6 in the east portion. Line 3 and line 6 can absorb the passenger flow if line 1 is closed.

Then after that maybe the west portion of line 1 up to Tiananmen can be closed; all the upgrades - lengthening the platforms, platform screen doors, and maybe the parallel R1 can be done all together. Then after this, the line 1 east portion can be upgraded, including merging Batong line.

Line 1 upgrade is very feasible, it is just a matter of finding an acceptable solution.

Line 2 is different, no direct replacement or alternative lines in case it will be closed for upgrade. Maybe wait for line 8 to get completed, and upgrade the western half and eastern half of the line 2 loop one at a time.

Until these upgrades are realized, the Beijing subway passengers might be as well get used to overcrowding.

Platform work on an existing and operational subway station doesn't necessarily mean closure. In Toronto they are adding another platform to an existing station and the station is only closed for short periods of time but is nevertheless operational 95% of the time. They just dig a trench down beside the station gradually knock down the wall and build while the stations operating. If they stagger the operationally obtrusive work to a few or even one station at a time; Line 1's operations will mostly be intact.

It is very feasible but their are different ideas floating in my head right now:

They could upgrade the entire line to support 8 car B size trains. That is the cheapest option as only the section between Pingguoyuan and Nanlishilu platforms need to be extended. Fuxingmen to Sihui East is already long enough for 8 cars.

or bundle with R1 and extend everything to support 10 car trains. The latter might be a bit of overkill but that's what I like about China; there is no such thing as overkill ATM

10-car line 1 + 8-car line r1 should not be an overkill in Beijing. In Hong Kong east rail line has even 12-car wide trains where it serve mostly on suburban areas.

In many Chinese cities increasing train capacity won't be a solution as the bottlenecks are not the train but transfer corridors. Just look at some stations in Shanghai, Beijing or whatever: in rush hour passengers do not have enough time to leave the platform as new once come from the next train. Consider, that even in rush hour headways are not that short.

there are not enough escalators by design. The metro stations are not big enough especially in Beijing. That said, everything has to be designed for long term in China because long term plans become short quickly. Not long ago people were arguing of the "too grand" HSR stations. Now many of them are already "too small" due to the high volume growth.

Shanghai has made some improvement on the newly built lines, i.e. line 13 and line 11 phase II installed more escalators to deal with the rush hour crowd.

What are the plans for Beijing metro for years 2013-2014-2015 per year?

I saw those handrails early this month in Beijing (in non rush hour) and was wondering why they are put there.
I always wondered why when ever I ride on the Beijing Subway, I spend equal amount of time riding on trains and transiting between lines 13 and Line 2... 1 min waiting for train, 15 min on train, 25 min going from one line to another, 1 min waiting for train, 10 min on train, arrive... I took that every day for about a month, and can't figure why I have to walk so long in one freaking station

Now I know why, this is insane!!!!

Well if they are going to lengthen the platforms they can build more transfer channels. Stations such as Jianguomen and Fuxingmen need to be rebuilt anyway they are undersized and poorly designed (Spanish solution anyone). You can see that newer stations such as Hujialou are more properly sized. To a certain extent it's a chicken vs. egg thing if the line capacity was higher then the platforms would be more clear. Part of the reason transfer stations are so crowded is because they are crowded with queuing people trying to get on the train not because there is too much people transferring. If the platforms are clearer then the trains have less dwell on stations and more trains can be put in, increasing line capacity.

That's not why - this is why (one big cluster of activities within the 4/5th Ring Rd):

In February of 2012, the transit planning authorities of Beijing proposed three new express lines: Line R1, which is planned to run parallel to the existing Line 1; Line R2 is planned to run parallel to (and east of) Line 5; and Line R3, whose planned route is currently unknown. I ask, what is necessitating the construction of these three new express lines?

That's like asking why Paris has the RER or why New York has express local service.

Beijing Subway Ridership as of July 2013:
Daily Average: 9.7503 million
Weekday Average: +10 million
Peak: 11.0552 million

Source

2013 annual ridership running total as of June 30: 1.266 billion

Source

According to Wikipedia if Beijing's semi-annual ridership is placed with the annual stats of other systems it would be the 9th busiest subway system in the world.

No as in if the Beijing where to have 0 riders for the rest of the year it would still be the ninth busiest in annual ridership. That being said based on my current projections (running total + days in half a year * avg ridership) Beijing will be the busiest subway system in the world by somewhere in 2014 if not by the end of 2013.

Dear friends. Can anyone help me showing pictures of all trains in Beijing subway. I would like to see especially the front part of each train with the indication of the line it runs on.

I want to try to make some models.

There is this kind fellow who made plan views of some of Beijing's rolling stock.

Also, if you search the rolling stock series number you will find tons of pictures of them.

Line 1
SFM04


Line 2
DKZ16


Line 5
DKZ13


moar later

Thank you very much Saiho. I'm still waiting for the other trains.

Way is the major difference between DKZ16 and DKZ13?
