Construction is underway for turning the large Darnytsia railway station on the left-bank part of Kyiv into a long-distance passenger hub, which may ease traffic at the central station. Bridges over the Dnieper River are another problem restricting the development of city's railway system. Presently, only one rail bridge out of two is available for intense train traffic. A new combined rail-auto bridge is under construction, as a part of Darnytsia project.
