where does the trans siberian railway begin and end
Trans-Siberian Railway The Trans-Siberian Railway (TSR, Russian: Транссибирская магистраль, tr. Transsibirskaya magistral', IPA: [trənsʲsʲɪˈbʲirskəjə məgʲɪˈstralʲ]) is a network of railways connecting Moscow with the Russian Far East.[1] With a length of 9,289 kilometres (5,772 miles), it was the longest railway line in the world before the construction of the Yiwu–Madrid railway line.  There are connecting branch lines into Mongolia, China and North Korea. It has connected Moscow with Vladivostok since 1916, and is still being expanded.
Transcontinental railroad A transcontinental railroad in the United States is any continuous rail line connecting a location on the U.S. Pacific coast with one or more of the railroads of the nation's eastern trunk line rail systems operating between the Missouri or Mississippi Rivers and the U.S. Atlantic coast. The first concrete plan for a transcontinental railroad in the United States was presented to Congress by Asa Whitney in 1845.[2]
