Rail hub · Santiago
South America’s second metro celebrated its 50th anniversary in 2025 — 7 lines, 143 stations, 149 km, 640 million journeys a year — and marked it by building three new lines at once. Lines 7, 8 and 9 plus the airport light rail will make Santiago’s the longest metro in Latin America by 2033.
Line 7 is the flagship: 26 km fully underground from Renca to Vitacura, 19 stations, $2.53 billion, opening late 2028. It gives Renca, Cerro Navia and Vitacura their first metro, relieves Line 1 by ~10,000 daily passengers, and runs on 37 driverless Alstom trains built in Taubaté, Brazil. Lines 8 (Providencia–Puente Alto, $1.9B, 2032–33) and 9 (into La Pintana, $2.73B, staged 2030–2033) follow; Line 9’s Cal y Canto station will be the first in the Americas where four metro lines meet. President Boric added Line A in June 2025 — a light rail linking the airport to Line 7’s Huelén station.
The metro’s daily miracle is the bip! card integrating metro, buses and MetroTren commuter rail in a single fare. The system carries about 46% of all public-transport trips in a city of 6.2 million — and it survived the 2019 social outbreak that torched stations, rebuilt, and kept every expansion date credible. Alstom, supplier of 75% of the rolling stock, marked 50 years of partnership in October 2025 — from the first 1975 trains to the autonomous Line 7 fleet.
The state railway EFE set its own record in 2025: 32 million passengers, with losses cut by more than 70 billion pesos. EFE Central led with 14.47 million (+5.6%), powered by the Chillán corridor, where six CRRC Sifang bimodal trainsets — 238 seats, 160 km/h, electric or diesel — have run since 2024 as the most modern passenger trains on the continent. The express covers the 397 km to Chillán in about three hours, three pairs a day.
The Santiago–Batuco commuter line and the Melipilla extension are in construction, the Tren Nocturno to Temuco keeps the overnight tradition alive as a tourist service, and Puerto Montt regained trains in 2025 as a pilot. Chile’s rail map remains a spine, not a net — but for the first time in decades the spine is growing vertebrae in both directions from Estación Central, Santiago’s 1897 landmark terminus.
The TIO Read: Santiago is the only city in this series where the metro is simultaneously a heritage system (1975), a social-pressure valve (2019) and the continent’s most ambitious build site (three lines at once) — and still runs 87%-style reliability through all three identities. The reviewer’s call: ride Line 1 at rush hour once to understand the city’s load, then time a 2028–29 return for the Line 7 + airport-rail opening — that pairing reprices the entire northwest; on EFE, the Chillán express is the best rail argument in South America right now — three hours, bimodal, and cheaper than the bus it beats.
