2. United States
The United States has several iconic urban transit systems, including a metro rail network spanning approximately 1,300 kilometers in major cities such as New York, Washington, D.C., Chicago, and San Francisco. The New York City Subway alone has over 470 stations and accounts for a significant portion of total national ridership. Although the pace of new metro expansions is slower than in Asian countries, the United States is heavily focused on modernization and resilience. President Biden's Infrastructure Investment and Jobs Act has set aside more than $66 billion for public transit improvements, including station refurbishments, fleet electrification, and climate-proofing metro infrastructure. By 2025, several cities intend to implement platform screen doors, AI-based scheduling systems, and the expansion of rapid transit lines. Ridership is steadily recovering following the pandemic, and cities are actively integrating metros with last-mile options such as e-bikes and on-demand shuttles.
3. India
India's metro network has grown exponentially over the last decade, covering 900 kilometers across 15 cities as of 2024. With over 390 kilometers of operational corridor, Delhi Metro remains India's largest. With the help of the Central Government's National Infrastructure Pipeline and Smart Cities Mission, India is on track to reach 1,200 kilometers by the end of 2025. Major upcoming projects include metros in Patna, Bhopal, and Kanpur, as well as phases of expansion in Mumbai, Bengaluru, and Hyderabad. India is also looking into indigenous signaling systems (CBTC), Make-in-India metro coaches, and solar-powered stations to reduce carbon footprints. Metro Neo and Metro Lite systems in Tier II cities demonstrate India's adaptable, cost-effective transit innovation to increase ridership, which is expected to exceed 5 billion per year by 2025.
4. Russia
Russia's metro system revolves around the Moscow Metro, which is one of the oldest and most beautiful in the world. The country has over 800 km of metro lines, with Moscow alone accounting for more than 300 km. Russia, known for its high efficiency and architecture, continues to invest in expanding metro rail networks in cities such as St. Petersburg, Kazan, and Novosibirsk. With a projected 150-kilometer network expansion by 2025, key trends include AI-powered surveillance, smart card-based fare systems, and station renovations to improve user experience. Moscow's Big Circle Line, one of the world's longest circular metro lines, exemplifies ambitious infrastructure development.
5. Japan
Japan is world-renowned for its high-speed railways, but its metro systems, particularly in Tokyo and Osaka, are equally impressive. With nearly 900 kilometers of track, Tokyo's metro transports over 8 million passengers per day. Japan's metro systems are known for their punctuality, safety, and seamless integration with suburban train lines. Innovations such as earthquake-resistant infrastructure, fully automated trains, and cutting-edge platform safety features have established global standards. Tokyo is expanding its lines ahead of the 2025 World Expo in Osaka, while other cities are focusing on capacity improvements and environmentally friendly practices.
6. South Korea
The Seoul Metropolitan Subway in South Korea is one of the world's longest and busiest, spanning 1,100 kilometers. Other cities with significant networks include Busan, Incheon, and Daegu. South Korea is at the cutting edge of metro technology innovation, with real-time crowd monitoring, free public Wi-Fi, AI-powered train controls, and high-speed fare gates already in place. The government is investing in smart urban rail, with automation, artificial intelligence, and green energy integration as key pillars. By 2025, Seoul intends to expand intercity metro connections and improve smart mobility through integrated apps and shared micro-mobility solutions.
7. United Kingdom
The UK's metro system has historical significance, with the London Underground being the oldest in the world. The network spans more than 400 kilometers and is being modernized extensively as part of the Transport for London (TfL) upgrade plan. The new Elizabeth Line (Crossrail) has added more than 100 kilometers of high-capacity track and improved East-West connections. Future trends include AI-powered train management, carbon-neutral operations, and increased service frequency. Metro projects are also underway in Glasgow and Manchester. Ridership is gradually returning to pre-pandemic levels, and TfL's Vision 2025 aims to implement driverless trains and contactless-only travel.
8. Germany
Germany has multiple metro systems (U-Bahn) in cities like Berlin, Munich, Hamburg, and Frankfurt. They collectively contribute over 700 kilometres of urban rail. Germany is well-known for its integration with regional rail (S-Bahn), but its primary goal remains to improve sustainability and accessibility. The country is investing heavily in its Climate Action Plan 2030 to electrify more metro lines and promote public transportation use. Berlin plans to expand its U-Bahn to underserved areas, while Munich is developing automated metro corridors. AI for predictive maintenance and real-time scheduling is a major trend for 2025.
