In 2015, Line 4A accounted for only 3.1% of all trips made on the metro system with a daily ridership of 56,400; it is the least used line in the system since it does not serve the city centre, as well as being the shortest line in the system.

History

Line 4A was originally conceived as a branch of Line 4, but due to the considerably low demand compared to the Puente Alto service, it was separated from Line 4 and inaugurated as a different service. It was inaugurated by President Michelle Bachelet and opened to the public on August 16, 2006. It runs between La Cisterna station and Vicuña Mackenna station.

On November 29, 2010 Santiago Metro workers struck, halting the service for 17 days.[1] The strike caused major over-crowding on bus services as passengers used them as an alternative to their daily metro rides.

Echeverría: The Ghost Station

Echeverría metro station, built but never opened to the public, is located between La Cisterna station and San Ramón station on the junction of Blas Vial street and Maria Vial in the commune of La Cisterna. The station remains partially built, with the platforms and footbridge across the highway already finished.

The station has never been completed due to the low density of residents in this area, although it could be finished and opened to the public if the population density increased.

Extensions

The line may be extended in the future to Del Sol station to connect with Line 5. The trench where the extension would run has already been built between the two lanes of the Autopista Vespucio Sur highway, ready for the extension to be laid down if the population were to increase in that part of the city. If built, the extension would serve the communes of La Cisterna, Lo Espejo, Cerrillos and Maipú.
