Linea 1 Metro is the oldest line of the Madrid Metro, running north–south through central areas of the Spanish capital. It connects major interchange stations and provides useful access to neighbourhoods and attractions while also representing an important chapter in Madrid's twentieth-century transport history.
Service patterns, station closures and engineering works can change, so consult the official network map before travel. Keep tickets or a valid transport card ready, watch belongings in crowded carriages and allow extra transfer time. Linea 1 Metro is functioning public transport rather than a sightseeing ride, and normal commuter etiquette applies.
