 Moving freight on the broad-gauge network is considered less expensive, as the lines can take more cargo (higher axle weight limits and higher maximum trainloads).Wider rolling stock can also be used on this gauge.The aim of the project is to expand European rail network by laying 1,520 mm broad-gauge lines from Košice in eastern Slovakia to Vienna, creating an uninterrupted transport chain from Russia, China, Japan and other Asian countries to Central Europe.
