The journey no doubt involved the longest railroad in the world, The Trans-Siberian Railway. Based on the reading, Dr. Perkins might have also ridden on the much-storied and strategic Chinese Eastern Railroad (CER: 東清鐵路, or Trans–Manchurian Railroad), which was owned jointly by Russian and Chinese in 1913. CER was a source of Russo-Japanese War of 1904–1905 as well as many other subsequent conflicts. It was handed back to China in 1952.
