SIEMENS Mobility has completed the installation of CBTC on Line 1 in Mexico City, as part of a wider programme to improve service quality, safety and operational performance on the oldest and busiest line on the metro network.
Opened in 1969, Line 1 runs for 18.6km from Pantitlán and Observatorio. The upgrade also includes the installation of a dedicated fibre-optic backbone to support digital communications as week as track renewals.
Siemens Mobility has supplied its Trainguard MT CBTC system for moving-block operation, enabling the minimum headway to be reduced to 100 seconds and delivering a 15% increase in line capacity and enabling Line 1 to carry 850,000 passengers a day. Metro operator STC expects shorter station dwell times, more even service intervals and a notable improvement in reliability once the system is fully operational.
Onboard CBTC equipment has been installed on the new Line 1 fleet of 29 series NM-22 trains supplied by CRRC Zhuzhou as main contractor for the upgrade project, as well as 10 refurbished series NM-16 trains. As signalling subcontractor, Siemens Mobility will also maintain the new signalling and train control system under a 16-year service agreement.
“We are enabling faster and more reliable journeys, setting a new benchmark for urban mobility in Latin America,” says Liubov Schachtner, CEO of Siemens Mobility Latin America and Brazil.
