Line F is a planned addition to the Buenos Aires Underground. In 2019, the government of Buenos Aires was looking for a group to create a plan of the line,[1] [2] but this study was cancelled in 2022.[3] The city decided to create a study with their own staff, which is still underway as of 2024. The estimated cost of the project has risen from 800 million dollars,[4] to 2 billion USD.[5]
Permission to construct the line was originally granted in 2001, in a sanction which also included lines H (partially completed) and line I (not started).
The line is set to be the most modern in the network, using automatic trains, a communications-based train control system like the one being installed on Line C, and platform screen doors.[6]
The line is also expected to have the highest ridership when compared to the existing lines, at 600,000 riders annually.[7] In the 2019 tender, eight of the thirteen stations were connected to other lines on the network.
In 2006, it was considered whether the two Line E ghost stations (San José vieja and Constitución) could be used as the southern point of Line F, considering they overlapped the line's trajectory. However, it was later decided that Line F would use a completely new tunnel with new stations given the frequency the line is expected to have.[8]
