@ First point: It's correct, but it's not the answer I'm
finding~
@ Second: How did they (LTA) know SMRT is going to win the
tender back then, and how did they (Alstom) know what to use for
the electrification? They started construction first before
bidding, like the case in Downtown Line now.
For the second point , when it started construction , it dosen't
mean they build the tracks together , it is only
the tunnelling works first then after tendering then only
build the tracks like the CCL .
