Russian operator T2 has launched 5G service in the metro systems of Moscow and St Petersburg, bringing next-generation mobile connectivity to two of the busiest underground transit networks in the country. Rival operator Megafon has moved in parallel, extending 5G coverage to railway stations.

The deployments mark a shift in Russian 5G rollout strategy toward high-traffic transport hubs rather than broad geographic coverage. Metro tunnels and stations concentrate millions of daily passengers, allowing operators to deliver meaningful capacity gains to large user populations without the expense of a nationwide network build.

For T2, the metro launch represents one of its most visible 5G milestones since the company's formation. The operator, created through the merger of Tele2 Russia with Rostelecom's mobile assets, has positioned itself as a challenger to the market's established leaders, and urban infill projects of this kind let it compete on network quality in the country's two largest cities.

Moscow's metro carries several million passengers on a typical weekday, and St Petersburg's network is the second-busiest in the country. Underground coverage has historically required dedicated distributed antenna systems and tunnel radiating cable, making metro builds more engineering-intensive than surface deployments of comparable subscriber reach.

Megafon's move to cover railway stations follows the same logic. Rail terminals combine dense crowds of commuters and long-distance travellers with high data demand, and operators across markets have treated stations and airports as priority 5G venues.

Russian operators continue to work within a constrained spectrum environment. The country has not yet held full-scale auctions for internationally harmonised 5G mid-band frequencies, and operators have largely deployed 5G using spectrum in existing bands, with high-band capacity deployments concentrated in dense urban zones such as stadiums, business districts and, now, transport hubs. Coverage announcements like these therefore reflect targeted capacity builds rather than continuous citywide 5G availability.

For commuters, the immediate practical effect is faster data speeds and better performance during peak hours at stations and, in the case of T2's build, along tunnel sections where the operator has completed equipment installation. Passengers on other networks will need to wait for their own operators' metro deployments, which have proceeded at different paces across the Russian market.

The timing of the announcements suggests operators see transport infrastructure as the next competitive battleground for 5G in Russia's largest cities. Additional station and line activations are expected as operators continue rolling out equipment across the two metro networks.
