Growth of cities has been phenomenal in the recent times, with more and more people starting to live in cities. As of 2023, round about 56% of the world’s population, equaling 4.4 billion people, are residing in cities, according to World Bank. However, rapid growth in urbanization requires efficient transportation networks across cities. Thus, the need to curtail traffic congestion issues, and the need to up the overall public transit system because of increasing urbanization, have driven the global public transit sector – the market struck $215.54 billion mark in 2022, and further projections indicate towards a whopping 7.6% annual growth rate of the market from 2023 to 2030! In terms of the overall transportation system, Stockholm (Sweden), Helsinki (Finland), and Zurich (Switzerland) are 3 cities of the world with the best public transit system, according to Insider Monkey article. Moreover, London (U.K.), Copenhagen (Denmark), and Berlin (Germany) are few others which are ranked amongst the best in Europe, and in the world, as well.

As such, the metro network becomes highly relevant to our discussion, as it is increasingly preferred by the people because of its reliability and environmentally efficient aspect. Moreover, metro network also results in significant reduction of traffic jams and pollution. In U.S. alone, in 2022, 134 billion gallons of gasoline was burnt out through the consumption of it in the transportation sector, which caused 1,476 million metric tons of carbon dioxide emissions, which results in climatic issues like global warming, according to Coltura.

The metro rail infrastructure market hit the $46.8 billion mark in 2023, with further expectations saying that it will continue to grow 6% annually, till 2032, according to Global Market Insights. The projection of the market is based on the increasing urbanization and resultant growth in cities. Moreover, environmentally friendly modes of doing anything is preferred in today’s era, and hence, more investments are put into transportation network, which requires a great deal of long-term commitment, to be transitioned into greener industry – and metro networks are one way to do it. For example, a new installation, the Grand Paris Express, is planned for the Paris Métro, which would add up a range of 120 miles through 4 new lines and 68 new stations.

According to a report from McKinsey, Asia is expected to spend the most money on building new metro and light-rail systems. Between the time frame of 2019 to 2025, they had put forward a goal to invest around $920 billion, back in 2020; the Middle East and Europe regions are also aiming to spend a lot, between $135 and $145 billion each. Few cities which are hoping to transition their rail system the most are Beijing, Kuala Lumpur, Shenzhen, and Singapore, each planning at least one rail project worth more than $5 billion, according to McKinsey.

In 2023, North America was seen to be involved in betterment of its metro network system. Money from the federal, state, and local governments is key for planning, building, and keeping up with metro systems. For example, in November 2023, the Biden Administration granted $1.64 billion to help expand the Metro-North Railroad’s Penn Station access, which included addition of four new stations in the Bronx.

Major companies in the US market are actively pursuing strategic initiatives to uphold and expand their market presence. Companies like AECOM (NYSE:ACM), Union Pacific Corporation (NYSE:UNP), and Norfolk Southern Corporation (NYSE:NSC), are prioritizing innovation, investing in research and development, and utilizing advanced technologies to improve the efficiency and sustainability of railway systems.

In January 2024, Norfolk Southern Corporation (NYSE:NSC) teamed up with 62 customers to complete industrial development projects in 2023. These projects, which expanded operations or established new facilities along Norfolk Southern’s rail network, totaled $3.1 billion in investment, creating over 4,150 new jobs as a result. According to Ed Elkins, Executive Vice President and Chief Marketing Officer, this collaboration reflects Norfolk Southern’s (NYSE:NSC) commitment to facilitating industrial growth and enhancing productivity. The company aims to demonstrate its reliability and efficiency as a railroad partner, supporting both existing and potential customers in their growth endeavors.

In February 2022, AECOM (NYSE:ACM) obtained funding for several significant rail projects across the U.S., through the Federal-State Partnership for Intercity Passenger Rail Grant Program. This program has allocated approximately $16.4 billion for various essential rail infrastructure projects along the Northeast Corridor and nationwide. AECOM’s (NYSE:ACM) ongoing projects include the California High-Speed Rail, the Lyon-Turin high-speed rail link, and the Metro Tunnel Melbourne in Australia.

Union Pacific (NYSE:UNP) is another key player in rail transportation, linking the western two-thirds of the United States by rail. It provides rail services from major West Coast and Gulf Coast ports to eastern gateways, interfaces with Canada’s rail systems, and serves major Mexico gateways. In late July 2022, Union Pacific (NYSE:UNP) announced a significant deal with Wabtec to modernize around 600 locomotives. The agreement, valued at over $1 billion, is the largest investment in modernized locomotives in the rail industry history, which aims to enhance the efficiency and effectiveness of Union Pacific’s locomotive fleet, according to Wabtec.

Few of the biggest metro networks in the world are in New York, Beijing and Shanghai; and to delve deeper into the realm of biggest metro networks existing in the world, let’s now jump to our list of 15 Largest Metro Networks in the World.

Methodology

To rank 15 Largest Metro Networks in the World, we used a weighted ranking system to assign a score to each metro system. This took into account three parameters, which included, number of stations, length of track, and number of lines. The figures for these have been sourced from various sources like CNN Travel and World Metro Database. The first two parameters, that are considered more noteworthy to describe the size of Metro Networks, were given a higher weightage of 40% each, whereas the third parameter was given a weight of 20%. With this we arrived at a score that incorporates all three factors and thus provides a thorough ranking metric; a higher score means a larger metro network. With this, we present to you a list of 15 Largest Metro Networks in the World.
