The Trans-Siberian Railway (TSR, Russian: Транссиби́рская магистра́ль, tr. Transsibirskaya Magistral; IPA: [trənsʲsʲɪˈbʲirskəjə məgʲɪˈstralʲ]) is a network of railways connecting Moscow with the Russian Far East. With a length of 9,289 kilometres (5,772 miles), it is the longest railway line in the world. There are connecting branch lines into Mongolia, China and North Korea. It has connected Moscow with Vladivostok since 1916, and is still being expanded.

It was built between 1891 and 1916 under the supervision of Russian government ministers personally appointed by Tsar Alexander III and his son, the Tsarevich Nicholas (later Tsar Nicholas II). Even before it had been completed, it attracted travellers who wrote of their adventures. Russia has expressed its desire for Pakistan to participate in the China–Pakistan Economic Corridor, by linking the Trans-Siberian Railway with Gwadar Port.

The railway is often associated with the main transcontinental Russian line that connects hundreds of large and small cities of the European and Asian parts of Russia. At a Moscow-Vladivostok track length of 9,289 kilometres (5,772 miles), it spans a record eight time zones. Taking eight days to complete the journey, it is the third-longest single continuous service in the world, after the Moscow–Pyongyang 10,267 kilometres (6,380 mi) and the Kiev–Vladivostok 11,085 kilometres (6,888 mi) services, both of which also follow the Trans-Siberian for much of their routes.
