context_page_description: The Madrid Metro is a rapid transit system serving the city of Madrid, capital of Spain. The system is the 12th longest rapid transit system in the world, with a total length of 293 km. Its growth between 1995 and 2007 put it among the fastest growing networks in the world at the time, rivaling many Asian metros such as the Shanghai Metro, Guangzhou Metro, Beijing Subway, and Delhi Metro. However, the European debt crisis greatly slowed expansion plans, with many projects being postponed and canceled. Unlike normal Spanish road and rail traffic, which drive on the right, Madrid Metro trains use left-hand running on all lines because traffic in Madrid drove on the left until 1924, five years after the system started operating.
  Trains are in circulation every day from 6:00 am until 1:30 am, though during the weekends, this schedule is to be extended by one more hour in the morning in 2020. Furthermore, the regional government intends to keep stations opened around the clock during these days from 2023 onwards.
  A light rail system feeding the metro opened in 2007 called Metro Ligero.
