Bogota Metro Line 1 Opens

An elevated 24 km driverless line, the first metro for a capital that has debated building one since the 1940s. Estimated date.

Bogota Metro Line 1 is an elevated, standard-gauge line of about 24 km and 16 stations under construction (started October 2020) from the southwest to Calle 72, on which Bogota currently has no rail service and relies on TransMilenio buses^[1][3]
Trains are six-car GOA 4 driverless units carrying nearly 1,800 passengers, with platform screen doors and 3-minute headways^[1][3]
On 2 September 2026 Mayor Carlos Fernando Galan set 15 March 2028 for the first passengers, with the project over 80% complete, construction finishing September 2027 and a trial operation period after that; this is more precise than the pin's June 2028 estimate^[3]
Earlier city material (Mayor Claudia Lopez) also targeted commercial operation in March 2028 and put the Line 1 cost at 22.3 trillion pesos (2017 value)^[2]
A metro was first raised in 1942 and debated for decades (1981 studies, 2009 study contract, 2013-2014 studies for an underground line) before the elevated design proceeded^[1][3]

Bogota Metro gets a launch date

Colombia One's own headline, "Bogota^[2] Metro gets a launch date," published 2 September 2026, is a more recent report than the 2028 mayoral projection cited elsewhere, though the page itself returned a 403 error and its specific date claim could not be verified.
