In the LTA's Land Transport Master Plan (LTMP) 2040, there will be studies to see if a new line can be built, between Woodlands, and Greater Southern Waterfront areas. If the line is built, it will be about 30 kilometres long, and will be completed as early as 2040. The line could serve around 400,000 houses, and lower the time needed for travel to the city by up to 40 minutes.
