The first train of Metro Line 1 successfully ran on the Bosa viaduct during an initial testing phase in Bogotá [1].
This milestone represents the first movement of a train on the system's elevated infrastructure, signaling the transition from construction to operational verification. For a city that has struggled with transit congestion for decades, the trial is a critical step toward a functioning mass transit rail system.
The test run occurred on Dec. 26, 2023 [5]. The train traveled between the Patio Taller and a point near the station located at the intersection of Avenida Villavicencio and Avenida Ciudad de Cali in the Bosa district [1, 4]. These movements were designed to verify the viaduct's performance and begin the broader testing phase of the Metro project [1, 2].
Officials described the event as a turning point for the city's infrastructure. Carlos Fernando Galán said, "Después de 80 años de espera, por fin Bogotá tiene su metro" [5]. The reference to an 80-year waiting period highlights the long-term political and logistical delays that preceded the current project [5].
Following these initial movements, the project will move into more rigorous evaluations. Upcoming tests are scheduled to include electric traction over a viaduct length of 5,700 meters [3]. These subsequent trials will ensure that the power systems, and rail alignments meet safety and efficiency standards before the line opens to the public.
The Bosa viaduct serves as a primary testing ground for the broader Line 1 rollout. By validating the structural integrity and the interaction between the train and the elevated tracks, engineers can identify necessary adjustments before the system expands across the city [1, 2].

The successful movement of the first train confirms that the physical infrastructure of the Bosa viaduct is capable of supporting the rolling stock. While the trial was a limited run, the shift toward electric traction tests over 5,700 meters indicates that the project is moving from static structural completion to dynamic systems integration, a phase where technical failures are most commonly identified and corrected before public launch.
