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.
