Survived tram line’s map, compare with former map


PCC rolling stock in present line


Moyada rolling stock in present line

As I wrote before, most tram routes have closed here, but I can’t find about those closed routes. Please write some details about those closed routes details from one point to another.

Well I was able to take a few pictures of Mexico City's metro from the platform but I can see why there are few videos because the system is so extensively used therefore crowded. I nearly had to shove myself into one of the trains and it was not even rush hour.

Please try to answer these -
1) Which is the busiest tram terminus?
2) Is there any plan to extend the network? If yes, please post some details including map.

What has been said before about Mexico City's rubber-tired metro is true. It does require a higher investment, and it's also true that for investment-saving reasons, lines A and 12 have steel-wheeled cars. Specifically, Line 12 has broken the paradigm about rubber-tired metro being the only train type to operate in the inner-city. Mexico City has an irregular topography, but it's not something to really worry about. Slopes are not that hard, compared to many other cities, and the area within the downtown and most of the center suburbs is flat (It is a dried lake-bed).
Choosing rubber-tired metro has something more to do with the advice and help Mexico City subway planners had from French engineers, I don't really know. Maybe at that time, having this topography and soil composition would indeed have required a different solution than steel-wheeled trains into deep-carved tunnels. But, in spite of all that, slopes, curves and stops are 'performed' well for a rubber-tired metro system, and it serves its function. Most of the system is built with street-cut boxed-viaduct underground solution.

-- Answers --

1) What is the target year of opening line 10 & 11?

There were more than two different plans for Lines "10" and "11", as well as other lines as far as "19" at one time, I recall one plan from 1985 which stated completion time by 2010 (not only lines 10 and 11, but all the other ones as well), and another from 1995 with goal year 2020. None of them are officially considered as being the current plans, so things can change at any moment. No one knows with certainty at this moment what will happen.

2) Why line 10 & 11 were not built earlier than line 12?

Seems like the potential demand of Line 12 was higher than the other ones, and since L12 project did not change over the years, and by the layout of built lines at that time, especially in the south area of Mexico City, made seem like Line 12 would be the best option for next line (since connected most of the existing lines heading south). As a reminder, Line 9 was built before Line 8.
Also, current Line "B" is a route fusion of 1985's Line 10 and B. "Current" plan (?) for Line 10 is where BRT Line 1 already is, so, as I said, no one knows.

3) Left side, right side or both side, - which type of platforms are in most numbers in Mexico City subway network?

Right side layout (used mostly for underground and elevated stations): 141 stations
Left side layout (used mostly for ground level stations): 36 stations
Both sides layout (Barcelona-style): 6 stations*
Terminal layout (3 tracks, 2 platforms): 12 stations

* Line 8 Garibaldi station has Both-side layout but since is used as the current terminal (expansion plans take this line as far as Line 3 Indios Verdes), the middle platform is closed (it lacks from usable escalators and hallways too)

4) Elevated, ground level or underground, - which type of stations are in most numbers in Mexico City subway network?

Underground, deep tunnel: 14 stations
Underground, street-cut: 101 stations
Ground Level: 55 stations
Elevated: 25 stations

* Line 1 Observatorio Station is located at the slope of a hill, longitudinally, so half station is ground level and the other half is 'underground', but is still considered ground level.

5) Which are the highest and deepest stations of Mexico City metro?

Deepest: Constituyentes station, line 7
Highest: Periférico Oriente, line 12

6) Which is the busiest metro station?

Station-conglomerate: Pantitlan station, lines 1, 5, 9 and A (Obviously)
Single station: Cuatro Caminos station, line 2

7) Which stations have interchange facility with suburban rail network?

Buenavista Station, line B
Ferreria Station , line 6
There are actual interchange hallways, like transferring to another line, no need to take a foot outside of the system, but you still have to pay and pass a turnstile.

8) Where is/are the depot(s) of the subway network?

Line 1: 19°24'56.96"N, 99° 4'50.18"O* (also serves Line 5) / 19°23'50.97"N, 99°12'9.08"O
Line 2: 19°27'45.95"N, 99°13'4.36"O / 19°20'38.34"N, 99° 8'26.17"O*
Line 3: 19°29'53.63"N, 99° 7'16.53"O* / 19°19'5.23"N, 99°10'27.63"O
Line 5: 19°30'12.16"N, 99° 9'1.14"O / 19°24'50.32"N, 99° 4'11.01"O
Lines 6/7: 19°30'21.62"N, 99°11'56.03"O*
Line 8: 19°20'32.15"N, 99° 3'3.20"O
Line 9: 19°25'12.79"N, 99° 3'45.63"O
Line B: 19°32'44.58"N, 99° 1'21.73"O*
Line 12: 19°17'5.83"N, 99° 1'6.70"O* (exclusive for Line 12 steel wheel cars)
Line A: 19°25'12.90"N, 99° 4'1.40"O / 19°20'44.21"N, 98°57'31.31"O*(exclusive for Line A steel wheel cars, different from L12)
* Major depots

Montreal and Santiago de Chile got advice from french engineers, too. At that time rubber-tired metros offered a more comfortable ride but since than steel-wheels improved, too. There are some problems with rubber-tired systems on wet surface. Did Sapporo-metro put their rubber-tired surface-tracks in a shelter for that reason? I´m not sure. But Monteal never built an overground metro with rubber-tires because of the harsh winters.

Surprisingly french-influenced Caracas-metro started with steel-wheels back in the early 80s. Caracas uses trains which were designed for the Teheran-metro-project, kept on hold due to political changes in the early 80s.

Do you have a map of the projected lines? Nice information about Mexico-city anyway.

Kind regards

Yup, and it's a nightmare. Speed is thrown down to 25 km/h or less when it's raining. Ground-level and elevated sections of routes suffer from this problems all the time, and there are no shelter structures in any line. Thank God there is no snow here... There are diffuse projects to build some kind of structure on Line 2 which possesses one of the longest ground level sections of the network, and it's very crowded.

Yes, but those official maps in spanish are harsh and dry so I won't post them here. I will make my own versions of those official maps in english, following the designer spirit.

I never imagined pneumatic traction suffering hydroplaning I suppose the speed restriction stem from poor drainage

I think it´s more about the high noise-level from squeezing. Heard this about the surface parts of Paris-Metro with rubber-tires.

Of cause there was another problem which is fixed since a long time. The fire in Montreal Honoré-Beaugrand siding-tracks in 1971 went that horrible not only but mainly because of the rubber-tires. But meanwhile all those metros have a special filling with nitrogen oxid or something like that.

Kind regards

Thank you very much Abbendymion for your details answer, but the depot's position is too complex. Can you name the places of those depot? Thanks again.

Mexico City's tram reminds me Adelaide & Sapporo because those cities also one line left and all other lines are closed.

Trains and stations are very modern. Do you have maybe some maps of extension of Mexico's metro system ??

This is a video I posted a while back showing various trains in Mexico City.

Go to 0.55 for some shots of the Mexico City tram! Enjoy

The video is great. The point changing of the tram reminds my city Kolkata, where like Mexico city, still a points-man changes track points manually with a long iron rod.

At last I got a details city centre map of Mexico City tram, when it was in peak point of patronage.

I applaud Mexico City's wide-scale adoption of 3-platform-dual-track stations one of the few smart ideas that transit planners of the day are capable of drumming up

Are there any plans to expand the suburban train? I remember reading once about a plan to extend it to Polanco as well as Naucalpan, but I have no idea if it got beyond just a fantasy.
