What you need to know:
The CDMX Metro has 467 electromechanical stairs, of these, 35 are under repair. Have you come across one?
You leave the house on your way to work. You take the orange limousine, let’s say at one of the Line 7 stations. You arrive at your destination. You go up the first escalators until…you come across another batch but ones that are useless. You upload them and you realize that dozens of people—among them older adults—are doing that marathon morning involuntary in the CDMX Metro.
If this scene seems familiar to you and you have experienced it, you have surely asked yourself two things: Why do the CDMX Metro escalators break down? And when they are already repairing them, why do they take so long to rehabilitate them?
Here we decided to ask the Collective Transportation System (STC)—via transparency—on the situation of escalators and solve a few “mysteries” chilangos that, usually, are more popular at the stations of Line 7, which runs from El Rosario to Barranca del Muerto.
Wrongly worn shoes and other ‘mysteries’ of the escalators that do not work in the CDMX Metro
The CDMX Metro is made up of 195 stations on its 12 lines. In this network, in turn, We can find 467 electromechanical stairs, of which 35 are under repair and maintenance.
This is 7.4% of the total escalators in the Metro —The STC itself told us that in the response to our request for transparency, just on December 1, although later (on the 4th) in networks it said that the percentage was 4%.
A couple of numbers more or less but the truth is that the Metro’s objective is that the availability of escalators is not below 95% —which in the responses via transparency we saw that availability is 92.6%.
What are the main fights on the Metro escalators? They range from loose baseboards, damaged step chain wheels, worn service and emergency brake pads, damaged drive chains, broken combs, damaged bearings, damaged speed reducers, damaged electronic boards or faulty contactors.
To that we must add the useful life of the stairs – the Metro has recorded stairs that were over 30 years old even though they should not be older than 20 – and… the use we give them with excessive load on the steps, vandalism or urine leakage?
Yes, in 2020 the CDMX Metro shared reports that urine leakage was one of the causes of the failuresby 25%.
We’re not done with these mysteries yet… Or well, not even that much. How many times have we seen Cinderella-style posts on the Metro networks?
Yes, according to the Metro, shoes stuck in escalators are also a headache.
For example, on December 4 at the Centro Médico station—on Line 9— the electromechanical stairs staff had to remove a piece of sole along with a shoelace stuck between a rung and the comb plate of a ladder.
Therefore, he recommended traveling in the direction of the stairs, not jumping or running on the steps, Be careful that the laces of your shoes or tennis shoes are tied well… and, of course, do not spill liquids.
Ok, but why does the repair take so long?
Although the CDMX Metro has a scheduled preventive maintenance plan and a corrective maintenance plan, the truth is that sometimes repairs take a long time.
For example, in the case of spare parts that become obsolete, it takes time for the Metro to replace them because they no longer exist on the market, you need to get specially manufactured spare parts or import them. And in the most extreme case, buy new stairs.
Stairs for lines 7, 3 and 9
We arrived at Line 7, which we take advantage of its fame to exemplify those days when we have to climb the stairs step by step because the electric ones don’t work and that implies a great effort because sometimes it seems like an endless path —You just have to keep an eye on the Camarones station.
The CDMX Metro Management knows about this situation and even recognizes that the stairs on Line 7 are already old and have suffered from demand.
Precisely for this reason, in 2023 the Metro announced the purchase of 12 escalators only for Line 7 —whose depth is between 25 and 30 meters, a fact that has led to the emergence of the myth around the orange line that it had been built as a nuclear bomb shelter and today we know, thanks to a request for transparency, that this is not the case. .
Four for Line 3 —which runs from Indios Verdes to Universidad— and two stairs for Line 9, which will close three stations starting December 17. Here you can check more information.
In theory, Users would see the arrival of this batch of stairs between 2023 and 2024 because the equipment has long delivery times.
AND The investment was distributed between 2023 and 2024. It is 271 million pesos.
That is, we will still have to wait until 2024 for the stairs of these lines to come into operation as scheduled by the CDMX government.
