How Medellín's Transport Crisis Reached a Breaking Point: A Week of Reckoning on the Metro

Medellín's urban rail network, long held up as the backbone of the city's social transformation, is showing its age in ways that can no longer be managed quietly. Delays on Line A, the original 1995 metro corridor running from Niquía in the north to La Estrella in the south, have stretched past 45 minutes on peak-hour runs this week, stranding tens of thousands of passengers at stations including San Antonio and Parque Berrío in the city centre. The Empresa de Transporte Masivo del Valle de Aburrá, better known as Metro de Medellín, confirmed Thursday that three of its oldest Siemens trainsets are currently out of service pending parts procurement.

The timing matters. Metro de Medellín crossed 900,000 daily passenger trips for the first time in a sustained week-long stretch back in March 2026, a milestone that underlined just how much more the network is being asked to carry compared to a decade ago. That growth was never matched by capital investment at the same pace. The Acuerdo Metropolitano 17 of 2019, which outlined a funding framework for fleet renewal, stalled repeatedly in the Área Metropolitana del Valle de Aburrá's budget committees and delivered only partial results by its original 2024 deadline.

A Neighbourhood Problem, Not Just a Station Problem

The pressure is not confined to the main line. In the northeastern comunas, the Metrocable lines serving barrios like Santo Domingo Savio and Andalucía have also reported irregular intervals this week, compounding the difficulties for residents who have no viable road alternative for their daily descent to the valley floor. The cable car infrastructure in those sectors dates to 2004, and equipment replacement cycles were supposed to begin in earnest by 2025 under the city's Plan de Desarrollo 2020-2023, a timeline that has slipped.

Community leaders in the Unión de Juntas de Acción Comunal of Comuna 1, Popular, have been raising the issue with the Secretaría de Movilidad at the Palacio de la Alpujarra since at least April, pointing to a pattern of short-notice suspensions that leave workers in Moravia and Aranjuez unable to reach jobs in El Centro and El Poblado on time. The secretaría has acknowledged the complaints in writing but has yet to table a concrete remediation schedule.

How the Numbers Tell the Story

Metro de Medellín's own figures, published in its Informe de Gestión for the first quarter of 2026, show on-time performance on Line A fell to 81.3 percent in March, down from 94.7 percent in the same month of 2023. Fleet availability, the share of rolling stock operational at any given time, dropped below 88 percent in May, the lowest recorded figure since the network's post-pandemic recovery period in 2021. A single replacement railcar from the current Alstom contract costs approximately 4.2 million euros, and the city's 2026 capital budget allocated only enough to cover two units, against an identified need for at least seven.

The broader urban development context adds another layer. The Tranvía de Ayacucho, running east through El Chagualo toward Oriente, has seen its own ridership climb sharply since the residential densification of Barrio Alejandro Echavarría accelerated in late 2024. That corridor was never designed to absorb overflow from a struggling metro, yet that is increasingly what it is being asked to do.

City hall has said it will present a revised fleet-investment proposal to Concejo de Medellín before the legislative recess ends on August 3. For commuters boarding at Bello or San Javier each morning, that date is the one that counts. In the meantime, Metro de Medellín is advising passengers to consult the real-time service alerts published on its official app and to allow an additional 30 minutes on peak-hour journeys, cold comfort for a city that spent two decades marketing its public transport as a model for Latin America.
