subway. What are the works that will benefit more than 850 thousand people per day

The subway of the City of Buenos Aires does not sleep and neither do its works. With their more than 64 km long, its 6 subway lines, a Premetro line and 108 stations, it continues to advance with numerous infrastructure renovation projects necessary to continue the modernization processes and offer a better service to the residents who use it every day.

Currently, works are being carried out aimed at guaranteeing and increasing the availability of trains and optimizing the operation of the facilities.

Modern technology is incorporated in order to allow a better frequency and greater security, which translates into a more reliable service for users of the network.

In order for users to make their trip more predictable, a series of works are being carried out. The sign that indicates which is the next train shows the technological advances that are being launched together with the operating company, Emova.

Signaling systems, which are formation control and protection systems, are being renewed. Its main function is to circulate safely by assigning routes and reporting the position of the trains to avoid collisions. In turn, they allow the position of all the trains in the track area to be displayed, from the Central Operations Post (PCO) and indicate to the driver the permitted speed.

Currently, the installation on Line D of the latest in signaling technology is being completed: CBTC (Communications-Based Train Control), which already exists on Lines C and H and which allows the closest approach between formations safely.

● On the track: the lateral signals, the track circuits (whose function is to indicate when there is a train on a certain section), the antenna system to communicate with the formation and the beacons that indicate to the train in what coordinates of the train are installed. section of the line is located.

● In cars: the communication equipment with the PCO, the equipment that controls traction, the train braking system and the equipment to know the location of the formation along the section of line (radar, odometer, etc.).

In this way, there is direct communication and an improvement in the quality of the information. This allows users to travel safer and to arrive on time.

Currently, 495 cars have air conditioning in service, which represents 75% of the total network. That is why the power lines had to be reinforced with higher power cables and current technology throughout the tunnels and improvements were made to the rectifier substations. In this way, in Lines C and D will increase power by 82% and will benefit more than 500,000 users.

This work will help meet the new demand for energy, as a result of the incorporation of air-conditioned cars and the extension of the network, as is the case of Line E, on which three stations were inaugurated in 2019.

Around 300,000 passengers per day circulated there before the pandemic. This work seeks to improve accessibility, evacuation and the combination between the lines. In this sense, a new access has already been inaugurated on Calle Sarmiento, much wider, with elevators and escalators, and new combination corridors. In addition, three lifts were incorporated that gave full accessibility to the Diagonal Norte station and partial (direction to Cathedral) to 9 de Julio.

The next stage will be key, as it will speed up the combination between lines, with the construction of a corridor parallel to the platform of the 9 de Julio station towards the Cathedral. In turn, it includes the expansion of both Diagonal Norte platforms, and the incorporation of an elevator that links the sidewalk and the platform to Congreso de Tucumán on Line D, auxiliary and ventilation rooms for all the stations.

The subway is designed as a complement to other means of transport to reach the destination avoiding the congestion typical of the land route. The bicycle is a great option to do short or medium distances to shorten distances in less time. The network of bike lanes is constantly expanding. One way to unite it with the subway was the installation of bicycle racks so that those who pedal to the stations have a place to leave their bicycle.

Those who want to continue the journey by bike can do so on lines A, B, D, E and H on working days from the beginning of the service until 8 a.m., from 10 a.m. to 4 p.m. and from 7 p.m. to closing, and on weekends week and holidays without restrictions. They must upload the bicycle or skateboard in the first and last car of each formation. The access area and the interior of the formations are signposted.

From December 1, 2021, the new contract with the company Emova is in force, which provides for investments in infrastructure and the incorporation of new cutting-edge technologies that will allow a better service to be offered, both in terms of the availability of trains and to the operation of the facilities as well as to the relationship with the users of the subway.
