Want NSL to be longer than EWL? Simple. Do the Kallang Line /
Extension (Refer to 1996 LTA whitepaper on page 57)
For me, I predict the "Kallang Line" will be going from Ang Mo
Kio, Bishan East, Lorong Chuan (Serangoon Garden), Woodleigh or
Potong Pasir, Jalan Besar, Lavender, Nicoll Highway (Another reason
why Kallang Line is never materialized, due to the collapse),
Marina East and Marina Bay.
It may need some major fine tuning, and it is a planned to be
16km long line.
I'd rather complete station objects first, before going on to
Marina Bay.
