The Downtown Line (DTL) is a medium-capacity Mass Rapid Transit (MRT) line in Singapore operated by the SBS Transit company. It runs from Bukit Panjang station in the north-west to Expo station in the east via the Central Area. Coloured blue on the rail map, the line serves 34 stations, all of which are underground. The DTL is the fifth MRT line on the network to be opened and the third line to be entirely underground. Originally planned as three separate lines, the lines merged into the Downtown Line in 2007 and construction began in three stages, finally opening throughout in 2017. At 41.9 km, the DTL is the longest underground and automated rapid transit line in Singapore. The line is set to be further extended in the 2020s. Stage 3e, an extension of the line to Sungei Bedok, is under construction and is scheduled to begin operations in 2024, while a new infill station, Hume station, is planned to open in 2025. An extension to connect with the North South line at Sungei Kadut station is also being planned and set to open in the 2030s. When fully completed in 2025, the line will be about 44 km long with 37 stations, and will serve more than half a million commuters daily.
