"branches of a tree" from the Plaza de Mayo, something Miguel Delibes described as "restrictive". Current expansion efforts seek to address those restrictions by creating more north–south lines and moving termini away from the city centre. The current expansion plan was approved in the year 2000 under Law 670 and has seen the creation of Line H, as well as the extensions of Line A and Line B westwards. However, in 2015 an alternative plan has been proposed which would make numerous amendments to the Law 670 plan. Works in progress Line H's extensions to the north from Corrientes to Plaza Francia, serving intermediate stations at Córdoba, Santa Fe and Las Heras, and south from Hospitales with stations at Nueva Pompeya and Sáenz, were initiated with ground-breaking ceremonies on 17 January 2012. Since then, following concerns that the construction of Plaza Francia station would damage the natural beauty of the area surrounding the Recoleta Cemetery, the station was relocated to Facultad de Derecho next to the University of Buenos Aires's faculty of law, with the change delaying the opening of the station until 2018. Cordoba and Las Heras were opened in December 2015, while Santa Fe opened in mid-2016, providing the line with a connection to Line D. The 20 new Alstom trains to serve the expected increase in passenger numbers as a result of the connection with Line D began arriving in the country in 2015. Planned lines The future expansion outlined in Law 670 would see the addition of three new lines. These lines' routes have already been approved by the Legislature of the City in Law 670. 39.3 km will be added to the network, expanding it to about 97 km in total length and providing several stations with various interchanges. This will also create new north–south routes, resulting in an appropriate network to avoid the city centre. The new lines will mean that more than two million inhabitants of Buenos Aires (accounting for about 70% of the city centre's population) will live within 400 metres of a metro station. The new lines will run between 56 new stations. Line F will run from Barracas to Plaza Italia in Palermo and will include 16 new stations. The planned route length of this line is 10.8 km. Construction was due to begin in 2020, once the northern extension of Line H is complete, and as originally planned, the
