Part 1 of Land Transport Masterplan 2013 here
As part of the Land Transport Masterplan 2013, two new MRT lines will be built and three existing lines will be extended. This will double the current rail network from 178 km to about 360 km.
The CCL will close the link between HarbourFront and Marina Bay stations and save commuters the hassle of making multiple transfers. The extension, which will also pass through Keppel, is expected to be completed by 2025.
The DTL will be two km longer by 2025 -- to run through the East Coast area. It will be connected to the East West Line and the Eastern Region Line, which will be ready by 2020, so that commuters can transfer between the Downtown Line and Eastern Region Line in the east.
The NEL will be extended northwards by one station to serve Punggol North including the new Punggol Downtown.
