Bogotá has little railway transit infrastructure, following the collapse of the tram network, although a number of plans hope to change that. The Bogotá Metro has been pushed forward by two successive governments, and construction began in 2020 with opening planned for 2028. Plans to construct railways in and out of the city, replacing defunct routes, have been delayed due to the pressing need for transport within the city. A tram train line using right-of-way from the defunct Bogotá Savannah Railway, known as RegioTram, will be opening in 2023.
