Mexico City Metro Clears Drainage Sump on Line B to Protect Electrical Systems

The Mexico City Metro has conducted essential maintenance work on Line B, focusing on clearing a drainage sump at the Bosque de Aragón station. The primary goal of this operation is to safeguard the crucial cable gallery located beneath the platform, thereby preventing potential electrical failures that could disrupt train services.

This desilting effort, which involved using a vacuum truck to remove sludge and clean the wastewater collection point, is part of the Metro's broader annual drainage program. The program specifically targets cable galleries that carry high and low-voltage electricity. Maintaining these areas free from water and humidity is vital to prevent corrosion of insulating materials and avoid short circuits.

The maintenance was carried out during nocturnal hours, typically between 1:00 and 3:00 AM, to minimize impact on the operational schedule. By ensuring the integrity of the electrical infrastructure, the Metro aims to guarantee the reliable operation of trains and maintain safety standards for passengers. This proactive approach is crucial for the continuous functioning of the aging subway system.
