Global Metro Rail Expansion: A New Era

The global expansion of metro rail systems has been remarkable in recent years. According to the article, the world has added almost as much track in the past decade as was built in the previous 150 years, reaching 20,453km in 2023. This dramatic growth signals that “the great era of metro railways is only just dawning.”

Key Trends:

China’s Dominance: China has emerged as the undisputed leader, growing from 19% of the global track network in 2012 to 43% by 2023. Cities like Shanghai, Beijing, Guangzhou, and Shenzhen now host the world’s four most extensive metro systems.
Developing World Growth: Major new systems have opened in cities across developing nations, including Dhaka, Salvador, Chennai, Hyderabad, Mumbai, Lima, Riyadh, Doha, Ho Chi Minh City, and Jakarta.
Post-Pandemic Recovery: Despite concerns that COVID-19 might create a “death spiral” for public transit, ridership has rebounded strongly. In 2023, 58 billion metro trips were recorded, surpassing pre-pandemic levels of 57.9 billion in 2019.
Environmental Impact: The shift of billions of passengers from roads to rails is helping save “hundreds of millions of metric tonnes of carbon emissions.”

Impact on Singapore

Singapore has been a pioneer in urban rail transportation in Southeast Asia, with its Mass Rapid Transit (MRT) system opening in 1987. The city-state’s experience with metro expansion offers valuable insights for the region:

Singapore’s Metro Evolution:

Singapore has continuously expanded its MRT network as part of its long-term transportation master plan, with the goal of making public transport the preferred mode of travel.
The city-state is implementing its Land Transport Master Plan 2040, which aims to create a “45-minute city with 20-minute towns” where 9 in 10 peak-period journeys can be completed within 45 minutes.
Singapore has embraced innovative technologies to enhance efficiency, such as driverless trains, predictive maintenance systems, and integrated transport apps.

Economic Benefits:

Singapore’s MRT system has become essential infrastructure supporting its economic development by ensuring efficient workforce mobility.
Property values around MRT stations have typically enjoyed premium prices, demonstrating the economic value created by transit connectivity.
The system has allowed Singapore to develop a car-lite society, reducing congestion and allowing more efficient land use than would be required for roads and parking.

ASEAN Regional Impact

The expansion of metro systems across ASEAN represents a transformative shift in urban mobility for the region:

Current ASEAN Metro Landscape:

Indonesia: Jakarta’s MRT opened in 2019, with expansion plans underway. The article notes that Jakarta now has a metro system, which represents a significant step in addressing the city’s notorious traffic congestion.
Vietnam: The article mentions Ho Chi Minh City’s metro as one of the newer systems globally. This marks Vietnam’s entry into the metro era, with Hanoi also developing its system.
Malaysia: Kuala Lumpur has been expanding its integrated rail network, although not explicitly mentioned in the article.
Philippines: Manila’s railway system continues to expand, addressing one of Asia’s most congested urban environments.
Thailand: Bangkok’s expanding metro network is becoming increasingly crucial to urban mobility.

Regional Challenges and Opportunities:

Chinese Influence: As noted in the article, China has become a major player in metro development globally. This extends to ASEAN, where Chinese companies and financing are involved in numerous projects.
Lessons from Failures: The article mentions challenges in Addis Ababa and Abuja with Chinese-built networks, and the struggles in Karachi. These cautionary tales provide valuable lessons for ASEAN cities in ensuring proper planning, maintenance capabilities, and governance structures.
Climate Resilience: ASEAN cities face particular challenges from climate change, making sustainable transport infrastructure even more critical.

Future Outlook for ASEAN:

Rapid urbanisation across ASEAN will continue to drive demand for efficient mass transit solutions.
The region’s growing middle class is increasingly expecting modern public transportation options.
As noted in the article, the most significant advantage may be “freeing hundreds of millions from the drudgery of endless traffic” – a particular pain point in many ASEAN cities like Manila, Jakarta, and Bangkok.
Integration of metro systems with other transportation modes (buses, ride-sharing, bicycles) will be crucial for maximising benefits.

Conclusion

The global expansion of metro rail systems represents a significant shift toward more sustainable and efficient urban transportation. For Singapore and ASEAN, this trend offers immense opportunities to address critical challenges of congestion, pollution, and urban livability. As the article suggests, a future with walkable city centres connected by efficient metro systems “will be better for the climate, for our economies and for human happiness, too.”

Analysis of Global Metro Networks

Historical Context and Recent Growth

The world’s first metro system, London’s Metropolitan Railway, began operation in 1863, marking a revolutionary change in urban transportation. For the next 150 years, metro systems gradually expanded to major cities across the globe, reaching approximately 10,922 kilometres of track across more than 130 cities by 2013. However, the most remarkable development has been the explosive growth in the decade since then, with nearly the same amount of track added in just ten years as was built in the previous century and a half. By 2023, global metro track reached 20,453 kilometres according to the International Association of Public Transport (UITP).

China’s Dominant Position

China stands as the undisputed leader in metro system development:

China’s share of global metro track grew from 19% in 2012 to 43% by 2023
The country now hosts the world’s four most extensive metro systems in Shanghai, Beijing, Guangzhou, and Shenzhen
Even in less developed regions like Guizhou province, the Guiyang Metro (operating for just seven years) now carries more passengers than Chicago’s L train, which has been running since 1893
China has 28 metro systems that are busier than Guiyang’s

Global Expansion Beyond China

The metro boom extends well beyond China, with significant systems recently developed in:

South Asia: Dhaka (Bangladesh), Chennai, Hyderabad, and Mumbai (India)
Latin America: Salvador (Brazil), Lima (Peru), Panama City, Quito (Ecuador)
Middle East: Riyadh (Saudi Arabia), Doha (Qatar), Isfahan (Iran)
Southeast Asia: Ho Chi Minh City (Vietnam), Jakarta (Indonesia)
Africa: Lagos (Nigeria)

Ridership Recovery Post-Pandemic

The COVID-19 pandemic represented perhaps the most significant challenge ever faced by urban public transportation:

Lockdowns and the shift to remote work devastated ridership and finances
Many feared a “death spiral” of declining ticket sales leading to service cuts and further passenger losses
Despite these challenges, global metro ridership has rebounded impressively
In 2023, metros carried 58 billion passengers, finally surpassing the pre-pandemic level of 57.9 billion in 2019
Financial recovery is following, with some systems like Transport for London posting operating surpluses after years of crisis

Challenges and Failures

Not all metro developments have been successful:

Ethiopia (Addis Ababa) and Nigeria (Abuja) have struggled with Chinese-built systems that opened in 2015 and 2018, facing issues with planning, infrequent service, and parts shortages
Pakistan’s Karachi, despite being one of the world’s largest cities without a metro, saw its commuter railway close in 1999 amid mismanagement and corruption
Efforts to revive some failed systems with additional Chinese investment have stalled

Benefits of Metro Expansion

The global shift toward metro systems offers multiple advantages:

Environmental Impact

The transition from roads to rails helps save “hundreds of millions of metric tonnes of carbon emissions”
While metro systems have similar carbon footprints to shared minibuses (a common alternative in developing cities), they offer significantly greater capacity and reliability.

Urban Quality of Life

Perhaps the most significant benefit is “freeing hundreds of millions from the drudgery of endless traffic”
Metro systems enable more walkable, dense urban centres rather than car-dependent sprawl.
This transformation promotes improved climate outcomes, economic efficiency, and “human happiness”

Regional Metro Development Patterns

Developed Economies

In established cities with historic systems, extensions are often “slow, multibillion megaprojects that can take decades to finish”
Despite high costs, these cities typically maintain strong public and political support for their metro system..s
Focus tends to be modernisation, accessibility improvements, and targeted expansion.

Emerging Economies

Most dramatic growth is occurring in rapidly urbanising areas of Asia, Latin America, and the Middle East.
These systems often face the competing challenges of serving existing dense urban cores while also shaping development in expanding areas.s
Chinese engineering expertise and financing have become a crucial factor in many new systems.s

Technological and Operational Trends

Automation

Newer systems increasingly implement driverless technology to improve frequency and reduce operating costs..
Advanced signalling systems allow for greater capacity on existing tracks

Integration with Other Modes

Successful metro networks are increasingly designed as the backbone of broader mobility systems.
Integration with buses, bicycles, and micromobility options extends the effective reach of the metro systems.

Financing Models

Public-Private Partnerships (PPPs) have become common for funding new metro construction
Value capture mechanisms allow cities to fund metro development through increases in land values near stations
Chinese state-backed financing has emerged as significant or a significant pathway for developing countries to fund metro projects

Future Outlook

The analysis of global metro growth suggests several future trends:

The centre of gravity for metro development will continue to shift toward Asia and other developing regions.
Climate concerns and urban congestion will drive further investment, even as costs increase.
Technologies enabling faster, cheaper construction will become increasingly important.
Metro systems will increasingly be judged not just on transportation metrics but on their contribution to broader urban sustainability goals.

The evidence suggests that, indeed, “the great era of metro railways is only just dawning,” with significant implications for urban form, environmental sustainability, and quality of life in cities worldwide.

“The real voyage of discovery consists not in seeking new landscapes, but in having new eyes.” – Marcel Proust.t

Mei Lin checked her watch as she descended the immaculate escalator at Singapore’s Dhoby Ghaut interchange. It was 7:15 AM, peak hour on a Tuesday, yet she moved effortlessly between the North-South, North-East, and Circle lines. After 35 years of operation, Singapore’s Mass Rapid Transit (MRT) had become more than transportation—it was the circulatory system of the island nation, moving nearly 3.5 million passengers daily across its 130 km network.

“Last trip before the conference,” she thought, mentally reviewing her itinerary. As an urban transportation consultant specialising in Southeast Asian metro systems, she had planned an ambitious journey to visit: five ASEAN countries today and the rapid transformation of the region’s urban rail networks.

Singapore: The Benchmark

Singapore’s MRT system has long been the gold standard in Southeast Asia. Opened in 1987 with just 6 stations on the North-South Line, it had expanded to over 120 stations across six lines by 2025. The newest addition—the Thomson-East Coast Line—represented Singapore’s commitment to making 80% of households within walking distance of a station by 2030.

As her train glided into Changi Airport Terminal 3 station, Mei Lin reflected on what made Singapore’s system exceptional:

Punctuality rates exceeding 99%
A seamless integration with buses and last-mile solutions
Advanced predictive maintenance systems that had virtually eliminated breakdowns
Fully automated driverless operations on multiple lines
Universal accessibility across the network

But Singapore’s success wasn’t merely technical—it was philosophical. The city-state deliberately built its urban development around transit nodes, creating a model of Transit-Oriented Development (TOD) that many cities now sought to emulate.

Bangkok: The Maturing System

Three hours later, Mei Lin was navigating Bangkok’s complex transit network. The Thai capital’s metro development told a story of perseverance and incremental progress. The BTS Skytrain, opened in 1999, now connects seamlessly with the underground MRT Blue Line, the Airport Rail Link, and newer additions like the MRT Purple Line.

“It’s remarkable how far they’ve come,” she thought, watching the elevated train sweep past chronic street congestion below. Despite opening decades after Singapore’s system, Bangkok has accelerated development impressively, adding over 110 km of track in the past decade alone. The system now serves approximately 900,000 daily riders.

Yet challenges remained evident. Unlike Singapore’s centralised planning, Bangkok’s network had developed under multiple agencies with limited coordination, resulting in separate ticketing systems and occasional gaps in connectivity. Recent efforts to integrate payment through the Mangmoom Card showed promise but hadn’t yet achieved the seamlessness of Singapore’s EZ-Link system.

Still, standing on the elevated platform at Siam Square—where the Sukhumvit and Silom BTS lines intersected amidst gleaming shopping malls—Mei Lin could see how rail transit was reshaping Thailand’s capital, creating new commercial centres and reducing dependence on Bangkok’s notoriously congested roads.

Kuala Lumpur: Complex and Expanding

A short flight brought Mei Lin to Malaysia’s capital, where the transit landscape reflected the country’s complex political history. Kuala Lumpur’s rail network—a mix of monorail, light rail, commuter rail, and heavy metro—had developed somewhat haphazardly since the Ampang Line opened in 1996.

“Three different operators and four separate systems,” Mei Lin noted as she transferred from the KLIA Ekspres to the MRT Kajang Line at KL Sentral, the city’s massive intermodal hub. Despite these historical challenges, Malaysia has recently made impressive strides. The MRT Kajang Line, opened in 2017, represented a new generation of Malaysian rail transit—sleek, modern, and designed to world-class standards.

The ongoing MRT Putrajaya Line construction sites she passed highlighted Malaysia’s ambition to double its rail network by 2027. When completed, it would become the longest fully automated metro line in Southeast Asia, at 52.2 km.

“They’re learning from past mistakes,” she observed, noting how the new lines were being planned with better integration and first/last-mile connectivity. The introduction of the unified My50 unlimited travel pass in 2019 had also boosted ridership significantly.
