LTA - RTS network will be doubled from 138km today to 278km by 2020.
I would like to know what will be the total length of our current and already announced RTS network, N-S, E-W, N-E, Circle, DTL, Thomson Line, Tuas Extension?
What new line may be added such that the RTS network will be doubled to 278km?
It will be interesting to derive that 278km.
the lines you have listed and with the LRT lines add up to 278km, as well as the existing line extensions.
