Mayor Carlos Fernando Galán oversaw the first train test on Bogota's Metro Line 1 viaduct on Friday, May 29 [1].
The event marks a critical technical milestone for a city that has faced decades of delays in establishing a mass rail transit system. Successfully moving a train on the viaduct validates the structural integrity of the elevated tracks and signals the transition from construction to operational testing.
The tests took place in the south of Bogota, specifically between stations one and two [1], [2]. This movement represents the first time a train has traversed the viaduct, fulfilling a schedule that designated 2026 as the year for such trials [3].
Project officials said that Line 1 has reached a 77% completion rate [4]. The current phase focuses on ensuring the rolling stock integrates correctly with the newly built infrastructure before the system opens to the general public.
This progress is part of a broader effort to modernize urban mobility in the Colombian capital. The city administration is working toward a target date for the start of commercial operations in March 2028 [1].
Galán said the test is a step toward advancing the infrastructure project after years of setbacks. The viaduct serves as the backbone for the elevated portion of the line, which is designed to reduce traffic congestion in the densely populated southern districts [1], [2].
“The event marks a critical technical milestone for a city that has faced decades of delays.”
The successful movement of the first train shifts the Metro de Bogotá project from a civil engineering challenge to an operational one. By validating the viaduct's capacity to support rolling stock, the city reduces the risk of major structural failures before the 2028 launch. However, the gap between this initial test and commercial service suggests a rigorous multi-year period of safety certifications and system integration still lies ahead.
