The new transportation network will span 4,500km and use domestically produced trains capable of reaching 400kph

Russian Prime Minister Mikhail Mishustin has announced plans for a massive high-speed rail (HSR) network. It is set to be the largest in Europe, spanning more than 4,500km (2,800 miles), and will use domestically built trains capable of reaching 400kph (250mph).
At a government meeting on Tuesday, the prime minister said the new line will cut travel time between Moscow and St. Petersburg from four hours to just over two. The network will also connect Moscow with Minsk, Adler on the Black Sea, Ekaterinburg in the Urals, Ryazan, and other cities.
“Travel between cities should be not only safe and comfortable but also not too time consuming,” Mishustin stated. “In the modern world, time is becoming increasingly valuable. Because of that, we are mastering technologies for faster travel and [are working] on a development scheme for high-speed rail infrastructure.”
He noted that the project has been approved by President Vladimir Putin and will be finalized within the next six months.
