The second-class fortresses are Kronstadt and Sveaborg in the Gulf of Finland, Ivangorod in Poland, Libau on the Baltic Sea, Kerch on the Black Sea and Vladivostok on the Pacific. In the third class are Viborg in Finland, Ossovets and Ust Dvinsk (or Dunamunde) in Lithuania, Sevastopol and Ochakov on the Black Sea, and Kars and Batum in Caucasia.
A third line of great importance is the junction line between the Transcaucasian railway - which runs from Batum and Poti to Baku, via Tiflis, with a branch line to Kars - and the railway system of Russia proper.
From Tiflis, nearly midway on this last line, a railway proceeds south as far as Erivan (234 m.), with a branch to Kars (48 m.).
