Kransovodsk is a location in 80 Days. It is a city in the Turkmen region of the Russian Empire. The Russians have erected a fort at the Gulf of Krasnovodsk in the city originally known as Kyzyl-Su (Red Water). It is an outpost from where military trains run to Afghanistan. The Ekaterinburg route is opened up by talking to a Russian officer in town. The military train headed to Merv actually ends up in Herat, as Fogg overhears that the Russians have changed the train's destination.
