The book I read to research this post was To The Edge Of The World by Christian Wolmar which is an excellent book which I bought from kindle. This book is about the Trans-Siberian Railway and its history. Although when we think of the Trans-Siberian Railway we the railway line from Moscow to Vladivostok which is the one that is wholly in Russia & Siberia there are actually several Trans-Siberian Railways including one that was built earlier and linked up with the Chinese Eastern Railway for part of its route. The railway had to be rebuilt wholly within the Soviet Union because there were concerns the Chinese might close the stretch of line they owned stranding Vladivostok. The distance from Moscow to Vladivostok is approximately 5,750 miles although a few miles has been shaved off the original route by installing some straighter curves along with bridges and tunnels in places. When the original line was built it was considered too expensive to build any tunnels and in some cases whole mountains were dynamited and removed to make way for the railway. It’s interesting that the distance from Saint Petersburg to Kamchatka is 9,000 so the railway only stretches for 2/3 of the total stretch of the Soviet Union. Having said that in terms of railway building it’s the biggest achievement ever undertaken and was built in an amazingly short period. The Russians were determined to open up Siberia and try to populate it. Anyway sent to prison in Siberia was allowed to become a resident there after serving their sentence which normally be from 4-20 years. Of course most of these people died in captivity. Before the railway was built there existed a railway from Saint Petersburg to Moscow and then on to Chelyansk. This meant 4,500 miles of track had to be layed to Vladivostok. Vladivostok was little more than a village at that time. 1/7 of the Soviet GDP was spent on building this railway which is a huge amount. In those days Russia had very few universities which meant people like engineers and architects had to be brought in from abroad. These people also had to teach Russian people their skills so they could eventually take over although this didn’t happen until the 1850′s. They used a gauge of 5 feet although not all the railways in Russia shared this gauge which meant when the Japanese invaded in Siberia they couldn’t just travel to Moscow on the train and hampered there attempted invasion no end. A lot of the reason for building this railway was a military one to enable the rapid mobilization of troops and later on there were even train based missile launchers in the Cold War although not that many. The Russian Czar did build a railway to Warsaw before the Crimean War as he thought any war would come from that direction in Britain & France attacked and was caught out a bit when the attack came via Stevatopol in the Crimea. The British built the first military railway to get supplies to the front line. This is a great book which I thoroughly enjoyed reading. Christian is apparently of Russian descent although he lives in Britain and I have reviewed other books by him all of which were consistently good.
