The Santiago Metro (Spanish: Metro de Santiago) is a rapid transit system serving Santiago, the capital city of Chile. Operated by the state-owned company Metro S.A., it is the largest and busiest metro network in the country and one of the most extensive in South America.
History
- Planning and construction – The concept of a metro for Santiago was first proposed in the 1960s. Construction of the initial line began in 1969 under the administration of President Eduardo Frei Montalva.
- Inauguration – Line 1, the system's first line, opened on September 15 1975, running east–west between San Pablo and La Moneda stations.
- Expansion – Subsequent lines were added progressively: Line 2 (opened 1978), Line 3 (opened 2000), Line 4 (opened 2005), Line 4A (opened 2006), Line 5 (opened 1997), Line 6 (opened 2017), and Line 7 (opened 2023). Ongoing extensions continue to increase network length.
Network
- Lines and length – As of 2024, the system comprises seven operational lines (Lines 1–7) with a total route length of approximately 140 kilometres (87 miles). An additional line, Line 8, is in the planning stages.
- Stations – The network includes more than 150 stations, many of which serve as interchanges between multiple lines. Stations feature a mix of underground, at‑grade, and elevated alignments.
- Rolling stock – The fleet consists of electric multiple units powered by a 750 V DC third rail. Rolling stock includes a variety of models built by manufacturers such as Alstom, CAF, and Bombardier, with newer units equipped with air‑conditioning, passenger information systems, and accessibility features.
Operations
- Service frequency – Trains typically run at intervals of 2–5 minutes during peak hours and 5–10 minutes off‑peak. The system operates from approximately 5:30 am to midnight, with variations on weekends and holidays.
- Ridership – According to Metro S.A. reports, average daily ridership in 2023 was around 2.5 million passengers, making it one of the most heavily used transit systems in the region.
- Fare system – Payments are made using the integrated contactless card Bip!, which allows seamless transfers between the metro, buses, and suburban commuter rail services. Fare structures are zone‑based and include reduced rates for students, seniors, and low‑income users.
Infrastructure and Accessibility
- Stations – Most stations are equipped with elevators, escalators, tactile paving, and audio‑visual announcements to accommodate passengers with reduced mobility.
- Safety – The system incorporates platform screen doors on several newer stations, extensive CCTV surveillance, and a dedicated security personnel presence. Emergency procedures and evacuation routes are regularly rehearsed.
- Sustainability – Energy‑efficient lighting, regenerative braking on trains, and the use of renewable energy sources contribute to the system's environmental initiatives.
Future Development
- Line 8 – Planned to run from Cerro Navia to Santiago International Airport, with construction slated to begin in the mid‑2020s.
- Network extensions – Ongoing projects aim to extend existing lines to underserved districts, increase train frequencies, and upgrade signaling systems to Communications‑Based Train Control (CBTC) technology to improve capacity and reliability.
Governance
Metro S.A. is a state‑owned enterprise overseen by the Ministry of Transport and Telecommunications. The company is responsible for planning, construction, operation, and maintenance of the metro infrastructure, as well as coordination with other public transport operators within the integrated fare network.
