Line 12 of the Madrid Metro is the longest metro line and the most modern today. It also has some important stations that link several municipalities in the south of Madrid. (Alcorcón, Leganés, Getafe, Móstoles and Fuenlabrada). Line 12 of Metrosur has a connection with Renfe and line 10 of Metro de Madrid at the moment. However, the extension works of Metro line 3 to El Casar (Line 12) have begun. So the connection will improve. There is also talk of the possibility of connecting metro line 1 with line 12 at El Carrascal station. Giving service in this way to hundreds of thousands of travelers. In addition, El Carrascal is a strategic station where the famous Westfield Parquesur de Leganés shopping center is located. Therefore, travelers will be able to reduce the time to get from their home to the shopping center and it would improve the connection of metro line 12, which is currently quite poorly connected.
