Because Slovakia lacks direct maritime access, cargo utilizes deep-water transshipment ports paired with bonded intermodal rail or direct road transport. The two primary paths are the Southern Route (via Port of Koper or Trieste) and the Northern Route (via Hamburg, Bremerhaven, or Rotterdam).
From Koper, regular block trains run directly to Slovak dry port terminals, such as Dunajská Streda and Bratislava, clearing EU customs locally without port congestion. Northern ports connect via the Czech-Slovak rail corridor into Žilina or Košice.
