Russia's 400 km/h high-speed railway to slash Moscow-Sochi travel time by 15 hours
Russia has confirmed plans for its first high-speed railway line, connecting Moscow and Sochi. The project aims to cut travel time dramatically while boosting transport capacity and tourism. Officials say it will be the fastest in the world, reaching speeds of up to 400 km/h.
Construction of the Moscow–Adler high-speed line began in 2025 under the Effective Transport System project. Russian President Vladimir Putin has called the route a key priority, emphasising its role in modernising domestic travel. Once completed, the journey from Moscow to Adler will shrink from 23 hours to just 7 hours and 50 minutes.
The line will form part of a broader network of five planned high-speed routes. These include connections to St. Petersburg, Minsk, Yekaterinburg (via Kazan), and Ryazan. Unlike most global high-speed railways, Russia's system will use a 1,520 mm track gauge—the first in the world designed for 400 km/h speeds. Officials claim the project will ease pressure on airports and increase railway capacity. It is also expected to stimulate business travel and domestic tourism. However, none of the five proposed lines are scheduled for completion by 2030, according to available reports. Worldwide, around 70,000 km of high-speed rail exist, with China accounting for 50,000 km. Russia's network, once fully built, would mark a significant expansion in high-speed travel infrastructure.
The Moscow–Adler line sets a new benchmark for speed in railway travel. Its completion will reshape long-distance journeys within Russia, offering a faster alternative to air and road transport. The project remains in early stages, with no confirmed finish date for the full network.
