Circum-Baïkal EMU drag : some background info...
Trans-Siberian railway was built from both ends, and they met on the Baïkal lake, which is approximately at half-distance between them. Most of Russia is quite easy terrain for railway building, the Ural "mountains" being not much more than the Belgian Ardennes... So it is understandable that when the railway builders met the Baîkal lake and its surroundings, they were quite afraid by the task lying ahead. Initially, the two parts were not jointed. Transport on the lake was done on ferry in summer, and via a temporary track laid on the ice in winter. However, the war between Russia and Japan created a surge of traffic so finally a line was built, first along the Angara river, from Irkutsk to the lake, and then on the shore of the lake.
In the 50ies, a dam was built on the Angara river, which caused the railway line along the river to be flooded. So another line, straight from Irkutsk to Sludianka, was built. With the flood, the line along the lake became a single-ended branch line, initially only used for local traffic, but now also by tourists. There are tourist trains organized almost daily in summer.
The map that I attached explains this situation : active lines in black and what remains of the original one in red.
Here is the train ready to depart from Baïkal station :
On the way (ladders are installed at each door to allow passengers to get off & on the train) :
And arrived at Sludianka, pantographs up, ready to depart to Irkutsk :
I hope you will pardon me to finish this with an almost non-railway picture showing the lake itself...
