Kaliningrad is located at the mouth of the navigable Pregolya (Pregel) River, which empties into the Vistula Lagoon, an inlet of the Baltic Sea.
Sea vessels can access Gda?sk Bay/Bay of Danzig and the Baltic Sea by way of the Vistula Lagoon and the Strait of Baltiysk.
Until around 1900 ships drawing more than 2 meters (6 ft 7 in) of water could not pass the bar and come into town, so that larger vessels had to anchor at Pillau (now Baltiysk), where merchandise was moved onto smaller vessels. In 1901 a ship canal between K�nigsberg and Pillau was completed at a cost of 13 million German marks which enabled vessels of a 6.5 meters (21 ft) draught to moor alongside the town (see also Ports of the Baltic Sea).
Khrabrovo Airport is located 24 kilometers (15 mi) north of Kaliningrad, and has a few scheduled and charter services to several destinations throughout Europe. There is the smaller Kaliningrad Devau Airport for general aviation. Kaliningrad is also home to Kaliningrad Chkalovsk naval air base.
Kaliningrad's Khrabrovo Airport is located near Khrabrovo. The airport mainly connects Kaliningrad to other Russian cities, but also offers flights to other cities in Europe. In Baltiysk, one can take a ferry toSt. Petersburg, Copenhagen, Riga, and Kiel. Kaliningrad's international train station is Kaliningrad Passazhirsky, which in German times was known as K�nigsberg Hauptbahnhof. Trains depart in the directions of Malbork, Berlin, Baltiysk, Moscow, St. Petersburg, Minsk, Kharkiv, Anapa, and Bagrationovsk. A unique feature of the Kaliningrad railway is that some tracks in the direction of Poland and Berlin have a standard gauge of 1,435-millimeter (56.5 in) track parallel to the commonly Russian broad gauge of 1,520 millimeters (60 in) mostly for strategic reasons during the Cold Warand nowadays for goods traffic. One platform at the Passzhirsky station can be reached on standard gauge over the former Ostbahn main line from Elbing (Elblag)
