translated from Spanish: Metro to invest 270 mdp to replace and renovate 80 stairs

The Mexico City Metro reported that 55 escalators on the network will be replaced between 2020 and 2021, and another 25 will be renewed.
Through a statement, the Collective Transportation System (STC) reported that the Metro has stairs that are up to 38 years old, when their lifespan is 20 years.
Currently there are 13 stairs with 38 years old on the Metro, and they are located on Line 4; In addition, there are 2 teams that are 36 years old, and 34 of Line 7 are 31 years old.

The 25 stairs to be renovated are located on Line 7; 9 on Line 9; 9 on Line 8; 6 on Line 3 and 6 on Line 4.
According to the Metro authorities, the age of the equipment hinders the process for the renewal of its mechanical or electronic spare parts, since many of these no longer exist on the market and must be ordered to manufacture.
Sinergman will be responsible for the acquisition and installation of electromechanical ladders, in which 270 million pesos will be invested, financed with support funds from the federal government.
Between March and May 2019, two accidents were recorded due to slams in the STC Metro’s escalators: the first occurred at The Mixcoac station on Line 7, leaving an injured 8 people as a balance.

In May 2019, four Metro users were injured with minor injuries after falling on the escalators of Line 9 Pantitlán station due to saturation.
Also, six months later, in November, the STC Metro reported a malfunction in the escalators on the central platform of Chabacano Station on Line 8. At the time one of the steps was damaged there were no users.
Last September, the owner of the Metro, Florence Serranía, said in an interview with the newspaper Reforma that, as part of the 50th anniversary of the STC the current administration outlined a program of deep modernization to this transport.
“We have technology from the early 2000s and we have 1970s technology, so we have to enter a Metro free modernization program. What we do today is going to be what sets the tone for a modernization process that has to last, at least 25 years,” he said.
The Metro CDMX has 467 electromechanical stairs distributed in the 12 Lines, and currently the companies that carry out the total maintenance of these: Otis, Shindler, Mitsubishi, IMEM and Sinergman.
