Key Takeaways:
Moscow has long viewed the 17 countries using the Russian 1520 mm railway gauge (former Soviet republics, Baltic states, Finland, and Mongolia) as the “1520 Empire,” a costly-to-change network that binds them economically and strategically to Russia.
Finland and the Baltic states have taken limited steps toward the international 1435 mm standard, while former Soviet republics remain on the Russian gauge despite Chinese pressure to add dual-gauge tracks for easier trade.
The greatest threat is now inside Russia itself: recent concessions allowing Chinese-standard tracks in the Far East may encourage other 1520 mm countries to switch, potentially ending Moscow’s “empire” rhetoric.
Moscow officials and Russian nationalists have long referred to the 17 countries – the 12 former Soviet republics, the three once-occupied Baltic states, Finland and Mongolia – which use the Russian railway gage of 1520 mm rather than the international gage of 1435 mm as “the 1520 Empire.”
Moscow commentator Igor Shumeyko is the latest to do so and like others points that that this special “empire” ties these countries together and sets them apart from others who must change carriages when they cross its border (fondsk.ru/news/2026/08/16/imperiya-1520-rossiyskaya-zheleznodorozhnaya-koleya.html).
He notes that from the beginning in the 19th century, Russian leaders have viewed this “empire” as something which helps Russia both economically and in terms of national security and that despite all the political changes in 1991 and thereafter, these countries have remained within it because it is enormously expensive to change the gage of railways.
Finland and the three Baltic countries have taken some steps in the direction of moving away from the Russian gate to the international one but mostly remain on the Russian standard (euroweeklynews.com/2025/05/07/finnish-railway-gauge-to-be-changed-to-that-of-sweden/ and ft.com/content/0fe9d0fb-23a8-4935-a2e9-2637f444c8ba?syn-25a6b1a6=1).
The former Soviet republics also remain on the Russian standard and thus allow Moscow to speak of the “1520 Empire,” Shumeyko says. But some of these countries are under pressure from China to lay international standard width tracks within existing Russian standard lines to ease trade.
But the biggest current threat to this “empire” is from China and it is within the Russian Federation itself. A decade ago, Moscow bowed to Chinese pressure and agreed to build a international gage track between the Chinese border and a Russian port (windowoneurasia2.blogspot.com/2016/04/bowing-to-china-moscow-for-first-time.html).
And earlier this year, Russia again made a special concession to China on the gage of a new track in the Russian Far East to increase trade and reduce costs of having to change the carriages of trains at the border (tkrus.pro/jd-koleya-china-russia/?ysclid=msxrniep1416903527,объясняем.рф/articles/news/rossiya-i-kitay-dogovorilis-o-stroitelstve-zheleznoy-dorogi/ and railjournal.com/freight/russia-and-china-increase-cross-border-capacity/).
As Russia gives ground to China on this issue, the other countries which still use the Russian gage undoubtedly will become more ready to do the same thing and for the same reasons. If they do, Moscow may eventually have to stop talking about the “1520 mm Empire” its railroads have helped it build and maintain even when political borders change.
