The Madrid Metro (Spanish: Metro de Madrid) is a metro system serving the city of Madrid, capital of Spain. The system is the sixth longest metro in the world though Madrid is approximately the fiftieth most populous metropolitan area in the world. Its fast growth in the last 20 years has also put it among the fastest growing networks in the world, rivaled by many Asian metros such as the Delhi Metro, Shanghai Metro, Guangzhou Metro or the Beijing Subway. Unlike normal Spanish road and rail traffic, Madrid Metro trains use left-hand running on all lines due to historical reasons. The Madrid Metro operates every day from 6 am-1:30 am.
A light rail system feeding the metro opened in 2007 called Metro Ligero (light metro).
