Barcelona Metro L9 is one of the city's most newest underground railway lines and opened in 2009.
The first section of the Orange Line runs from La Sagrera, which will soon rival Sants Estació as Barcelona's main overground station, to Can Zam in Santa Coloma de Gramenet.
The second section of the Orange Line opened in March 2016 and goes from the Zona Universitaria, which is also on the Green L3 Line, to Barcelona El Prat Airport.
When work is finally completed the Orange Line will also cross the city centre and at 47.8 km the L9 will be the longest underground railway line in Europe.
You can buy single journey tickets and a variety of travel cards, including the excellent value T10, in the machines in the FGC and metro entrances.
However, if you are visiting for a few days, it is well-worth investing in a Barcelona Card, which not only gives you full access to the Barcelona integrated transport system, including metro, buses, trams, ferrocarrils but also discounts on Barcelona museums and tourist sights as well as in some shops and restaurants.
* Incidentally, the price of a ticket from anywhere on the Barcelona Metro Network to either of the Airport stops is €4.50 and other travel cards are not valid.
Number of Stations: 8
