越洲铁路是横跨大陆的铁路，通常是由海去海的模式。由于欧洲的铁路都是以十字体的方式铺排的，严格来说算不上越洲铁路，除了东方快车行经的铁路例外。

A transcontinental railroad is a contiguous network of railroad trackage that crosses a continental land mass with terminals at different oceans or continental borders. Such networks can be via the tracks of either a single railroad, or over those owned or controlled by multiple railway companies along a continuous route. Although Europe is crisscrossed by railways, the railroads within Europe are usually not considered transcontinental, with the possible exception of the historic Orient Express.
