Why they must close the Jurong East!!!!????
If that is the case, it would be
EWL: Pasir Ris - Clementi, Joo Koon - Lakeside. (Chinese Garden
is possible only with 1 train on either of the platform)
NSL: Marina Bay - Bukit Gombak (Bukit Batok will be the Chinese
Garden's version in NSL)
My suggestion is to have a shuttle train in:
EWL: PSR - CLE, CLE - JUR (Middle platform), JUR - LKS (WB), LKS
- JKN
NSL: MRB - BGB, BGB - JUR (Only to use NB / WB platform for both
direction)
Whether or not, it's already finalised and it's SMRT's decision
to close the station for that weekends. No point arguing on
alternative methods.
