The North South MRT Line was the first Mass Rapid Transit (MRT) line in Singapore. The line is currently 44 km long with 25 stations, and is operated by SMRT Corporation. Traveling from one end of this line to the other end takes about one hour, and this line is coloured red on the rail map. As the name implies, the line connects central Singapore to both northern and southern parts of the island. Cross-platform transfer to the East West Line is provided at Jurong East, City Hall and Raffles Place stations while transfer to the North East Line is possible via a linkway at Dhoby Ghaut station. When the Woodlands Extension was opened in 1996, the Branch MRT Line consisting of the route from Jurong East MRT Station to Choa Chu Kang MRT Station was integrated into the main line.
