Subway line H, the yellow line, is together with line C one of the two transversal lines in the city. Both lines connect lines A, B and E with each other. Currently, it runs all the way from Corrientes to Hospitales.
The line has been given three new stations. Two are being opened half December 2015 on Las Heras and Córdoba. The other one is being opened in April 2016 on Santa Fe and will connect line H with line D. The new connection with the D line should also make the C line less crowded.
This is not the only improvement of the H line. The city of Buenos Aires has also purchased 120 new subway carts. They come with air conditioning, sound warning stations and surveillance cameras. The subway carts should all be switched out by August 2016. This will allow the frequency of trains to drop from 6 minutes between trains to 3 minutes.
