From my previous reply, CCL terminates at Millenia station and not HarbourFront station, forming a circle.

I read before there may be a "North Coast MRT/LRT Line" from Woodlands/Sembawang to Pasir Ris/Changi Airport via Simpang, Seletar and Punggol.
Back to Circle Line (These station names are "working names" only):
Stage 1: Dhoby Ghaut > (S'pore Arts) Museum > (Suntec) Convention Centre > Millennia > Nicoll Highway > Stage 2
Stage 2: (Stadium) Boulevard > Old Airport Rd > Tanjong Katong > Paya Lebar > MacPherson > Upper Paya Lebar > Stage 3
Stage 3: Bartley > Serangoon > Lor Chuan > Bishan > Marymount > Stages 4 & 5
My assumptions for Stages 4 & 5: Lornie Rd > Eng Neo Ave > Sixth Ave > Ghim Moh > Buona Vista > NUH > South Buona Vista Rd > Pasir Panjang Rd > PSA Building > HarbourFront > Keppel Rd > Marina BayFront > Millennia (Stage 1 station), thus forming the Circle Line.
