Alstom Implements Signalling System in Argentina

Argentina: Alstom has finished implementing a new signalling system that is installed on the renovated San Martín Line viaduct.

The cutting-edge electronic system now handle all signalling along the six kilometres of new track between Palermo and Villa del Parque stations.

Autopistas Urbanas S.A. (AUSA) hired Alstom to deliver the new signalling system for the new viaduct. To future-proof the system, it is compatible with the future electrification of the San Martín Line.

Ernesto Garberoglio, Country Managing Director of Alstom Argentina, said:

“It is important to highlight the Alstom Argentina team, because this was a different project for everyone. We were used to working inside the subway in tunnel activities, but the viaduct project was completely different because we faced especially the Covid-19 pandemic, adverse weather conditions and high-altitude work with a high risk, but we overcome all the obstacles we encounter. I also highlight the willpower, experience and leadership of this Alstom team to make the best decisions in the most adverse situations on the project, and always with a sense of urgency.”

In 2019 Alstom started the mobilising and installing phase. The installation of track 4 started in 2o20 and was set for completion by March 2020. The commissioning work was performed during the quarantine period, involving individual tests, integrated tests and the validation of the installed system.

The scope of Alstom’s contract with AUSA consisted of delivering the design, development, installation, testing and commissioning of the new signalling system, maintaining the required safety levels, quality and availability for the installation of the new interlocking on the 5km section between Palermo and La Paternal stations.

Luciano Barbieri, Vice-President of Alstom Digital Mobility for Latin America, said:

“This new system features a modern operating table in La Paternal, new electro-hydraulic machines for the movement of track changes, new signals with LED traffic lights and new audio frequency track circuits. In the future this will allow to improve the frequency between the trains, and the safety of the system is absolute both for the passengers as well as for all employees of Argentinian Trains working on the San Martín Line.”

During peak activity on the project, Alstom Argentina employed 50 individuals. The company will also provide 15 months of technical support from the start of the new signalling system.
