Lake Burlinskoye, a salty lake located in Russia’s Altai region close to the border with Kazakhstan, is famous both for its pink color during the summer and the freight train passing through it every day.

Seeing an old freight train seemingly floating over a pink lake in Western Siberia is quite a bizarre experience, but somehow it all makes sense. Lake Burlinskoye is the largest single salt deposit in Siberia, with a saltiness that rivals that of the Dead Sea. It is precisely this exceptionally high saltiness that attracts a species of microscopic brine shrimp called Artemia salina which, as they multiply, end up turning the lake bright pink during the summer months. Siberia’s pink lake is a strange enough sight, but what really sets Burlinskoye apart from other bodies of water is the freight train traversing it several times per day.
