How big is Dubai’s Gold Line against other driverless metros worldwide

Dubai: Dubai’s planned Gold Line will add 42km to the emirate’s metro network, taking the total length from 120km to 162km, according to the Roads and Transport Authority (RTA). The expansion will also increase the number of stations from 67 to 85, marking a 35% increase in network size.

Within fully automated metro systems, Dubai is now among few cities operating large-scale driverless networks.

The Riyadh Metro has a planned network length of 176km across six lines, making it the largest driverless metro system currently under rollout, according to official project data and regional transport reporting.

With the addition of the Gold Line, Dubai’s metro network will reach 162km, narrowing the gap with Riyadh to 14km.

Dubai Metro has operated as a fully automated system since its launch in 2009. Its Red Line, at 52km, was previously recognised by Guinness World Records as the world’s longest driverless metro line at the time of its opening.

Globally, metro networks vary significantly in size, with the largest systems concentrated in Asia.

These systems have expanded over several decades through multiple lines and phases, serving large metropolitan populations.

In comparison, Dubai’s metro network will reach 162km after the Gold Line, placing it below the largest global systems but within the range of mid-sized urban networks.

Asia accounts for the majority of global metro expansion, with several cities in China, Japan, and India operating networks exceeding 300km, according to international transport bodies such as the International Association of Public Transport.

Metro development in these regions is driven by population density and urban scale, with continuous additions of new lines and extensions.

Metro systems in Europe and North America are typically older and more established, with slower rates of expansion.

These systems remain among the most intensively used globally, but their expansion tends to be incremental compared with newer networks in Asia.

Dubai’s metro network stands out for being fully automated across all lines, a feature not common among larger global systems.

The current network includes:

With the Blue Line under construction (30km, 14 stations) and the planned Gold Line, the network will expand to 162km and 85 stations, according to the RTA.

Dubai Metro currently serves around one million passengers daily, accounting for approximately 40% of public transport use in the emirate, according to RTA data.

Since its launch in 2009, the system has carried more than 2.8 billion passengers, including 295 million in 2025, marking a 7% increase compared to 2024.

By comparison, metro systems in cities such as Tokyo, Beijing, and Shanghai carry several million passengers daily, reflecting differences in network size and population.

According to the RTA, the line is expected to:

This approach differs from large-scale expansions seen in major Asian cities, where new lines often extend coverage across wider urban regions.
