Joker lah, DTL 3 can never be above ground. This is mentioned
and confirmed.
Well, I dont believe DTL 3 can built 50m underground as
well.
PS: The highest aboveground station is the proposed EW30 mega
interchange, where at least 20m in height..... Tuas Extension and
DTL 3 also can confused??
Eh EW30 is not Part of the MRT/LRT MAP
