Overview
- Pre-dawn on March 1, a partial collapse during a concrete pour at Monterrey’s Line 4 Obispado works injured construction staff, initially reported as four and later confirmed as five.
- Nuevo León authorities cited a shoring system failure that brought down the formwork, suspended activity at the site, and announced a review of safety protocols.
- In Madrid on Feb. 27, an electrical fault in the catenary halted Line 6 between Diego de León and Cuatro Caminos, with Metro estimating repairs would take more than two hours and warning of wider delays.
- CDMX detailed 2026 Line 2 rehabilitation with special hours at Viaducto, Chabacano, and San Antonio Abad—weekdays until 22:00, Saturdays until 20:00, and closed Sundays—while the rest of the line operates on split segments.
- On Feb. 28, CDMX Metro users reported delays of up to 25 minutes across several lines as officials worked to dispatch more trains, and Metrobús confirmed Line 2 station closures and a temporary suspension between Tepalcates and Constitución de Apatzingán, plus a Line 3 restriction near Centro Médico.
