They are seven research folders those who have raised the Mexico City Attorney General’s Office (FGJCDMX)due to incidents in the lines 3, 5, 7 and 12as well as in a workshop from the terminal The rosary of Metro Collective Transportation System (STC).
“Three in Potrero – La Raza, Atlalilco – Ermita, and Polanco; the fourth for the discovery of an automatic pilot sensor at the Hidalgo – Guerrero interstation; the fifth due to the derailment of one of the motor cars in the El Rosario workshop area; a sixth due to a short circuit at the Barranca del Muerto – Mixcoac interstation; and finally, one due to a short circuit at the Air Terminal – Hangars interstation,” said Ulises Lara, spokesman for the FGJCDMX.
Subway Polanco
Regarding what happened on January 15, at the Polanco station on Line 7, where there was an uncoupling of two carriages, the inquiries led to maneuvers being carried out with the intention of causing a serious incident.
This, due to the fact that the semi-automatic couplings or coupler known as “Scharfenberg” must be carried out every 6 months, which was fulfilled by the technical personnel in the workshops; in addition to the fact that the useful life of the pieces and their elements were suitable according to the temporality in the piece marked since the last revision control.
The spokesman for the prosecution said that “indications were identified in one of the wagons that show recent maneuvers in the area where the piece was located, such as the absence of witnesses that show the correct points of attachment of the pieces, among other actions, that they cannot be carried out with the train moving”.
Regarding the adjoining wagon, he indicated that the experts did not locate evidence of tampering.
Due to this action, an investigation folder was opened against whoever is responsible, since for these operations the possible commission of the crime of malicious damage in communication routes is presumed.

In the hours prior to the reopening of the underground section of Line 12, in the Atlalilco – Mixcoac section, the work supervisors detected at the Ermita station that the rail change box was beaten and out of place.
This track device is in charge of changing the direction of the train to carry out track change maneuvers at interstations and link tracks, so if it is damaged it can cause damage to the facilities, derailment or train crash.
It was for this reason that the prosecutor’s office carried out the pertinent expert reports and determined that it was an intentional action, since the device was hit with the aim of rendering it useless and consequently a risky operation for the transport system.
Damage to the track change mechanism and its cover forced them to be replaced to rule out any risk of collision.
