Actually Russian gauge is not 1524mm, but 1520mm! Finland has unique gauge not used anywhere else in the World, although that 4mm difference allows most bogies to be compatible with both of them, international trains can run through the border without bogie exchange.
So the point of the article is right, butnot perfect in details. I love trains.

However, as the text says “early 20th century”, 1524 mm was the nominal gauge of soviet/russian railways until the 1970s.
