The Trans-Mongolian Railway connects Ulan-Ude on the Trans-Siberian Railway in Buryatia, Russia, with Ulanqab in Inner Mongolia, China, via Ulaanbaatar, the capital of Mongolia. [...] The 1,110 kilometres of the railway in Mongolia (as of 2017) are managed by UBTZ (the Ulaanbaatar Railway Company), a 50/50 Russian–Mongolian joint-stock company.
