The system is expected to deliver a 15% capacity increase on Mexico City’s busiest metro line.
SIEMENS Mobility has completed the installation of the CBTC on Line 1 in Mexico City, as part of a broader program to improve service quality, safety and operational performance on the oldest and busiest lines on the metro network.
The first line was opened in 1969 and runs 18.6 kilometers from Pantitlan and Observatorio. The upgrade also includes the installation of a custom fiber optic backbone to support digital communications within a week of the track being refurbished.
Siemens Mobility supplied its Trainguard MT CBTC system to operate the moving block, allowing the minimum advance to be reduced to 100 seconds, providing a 15% increase in line capacity and enabling Line 1 to carry 850,000 passengers per day. Metro operator Saudi Telecom Company (STC) expects shorter station stays, more equal service intervals, and a noticeable improvement in reliability once the system is fully operational.
CBTC equipment was installed on board the new First Line fleet of 29 NM-22 series trains provided by CRRC Zhuzhou as prime contractor for the upgrade project, as well as 10 refurbished NM-16 series trains. As a subcontractor, Siemens Mobility will also maintain the new train’s signaling and control system under a 16-year service agreement.
“We are enabling faster and more reliable journeys, setting a new standard for urban mobility in Latin America,” says Lyubov Schachtner, CEO Siemens Mobility Latin America and Brazil.
