For most of its existence, the Sakhalin Railway was an anomaly -- a narrow-gauge network built by one empire, inherited by another, and too isolated to connect to anything. Its trains ran on tracks that matched Hokkaido's railways but not Moscow's, powered by Soviet diesels pulling Japanese-built railcars, in a place where the only link to the mainland was a ferry.
