ndmmxiaomayi SG From AMK to Jurong East , from Redhill to Boonlay , from Kallang (not so sure) to Changi and Pasir Ris and Bishan. NEL all underground... not sure for Circle Line.
SBS9889U SG Maybe its time for MRT Maps to differentiate underground and non underground station by dotted lines
SMRT 32373238 SG lol u forgot bishan... the question was NOT underground... BSH ground lvl mah... ok well CCL BSH stn is underground la... i guess future no more elevated stns liao... except pioneer and joo koon... unless maybe there is a North Coast Line by the time we're using wheel-chairs and walking sticks to get around... NCL's location might be feasible for elevation... if its even on the planners' minds...
Y_Shun SG i favour elevated stns more than underground.... underground u only see black surroundings, but elevated, at least you can see the surroundings and makes mrt a kind of 'tourist attraction'.
