What about the train visa from Beijing to Moscow?

Legal analysis: To take an international train from Beijing to Moscow, you can choose K3 (Beijing Railway Bureau) and K 19 (Moscow Railway Bureau), and you must apply for a Russian tourist visa. K3 also needs a Mongolian transit visa to pass through Erenhot, because the train needs to pass through Mongolia (via Ulaanbaatar) to go there; K 19 does not need a Mongolian visa to pass through Manzhouli.

Legal basis: Article 15 of the Law of People's Republic of China (PRC) on Exit and Entry Administration, foreigners should apply for entry visas to their embassies and consulates in China. You can apply for an F-shaped ordinary visa for visits, exchanges and inspections in China; To travel to China, you can apply for an L-shaped ordinary visa; To engage in business activities in China, you can apply for an M-shaped ordinary visa; Those who study and practice in China can apply for an X-shaped ordinary visa; Those who work in China can apply for a Z-shaped ordinary visa.
