100 YEARS OF THE TRANS-SIBERIAN RAILWAY

Today, a journey across Russia's Trans-Siberian railway takes about a week.

But exactly 100 years ago, upon its official completion, the trip took almost a month because the train trundled along at 20 miles an hour. 

Now the longest train line in the world, stretching more than 5,700 miles from Moscow to Vladivostok, the Trans-Siberian railway crosses two continents, 80 towns and cities, 16 large rivers and eight time zones.
