There was somebody said potentially is NEXT to the NEL platform
(Known as current Platform A is a "middle platform") but I doubt so
(Source from LTA MRT map where you can compare various interchanges
logo from Tanah Merah / Jurong East one, City Hall / Raffles Place
and Outram Park / Serangoon / Dhoby Ghaut / Bishan. Harbourfront
one is same as Promenade [With inclusion of DTL] / City Hall /
Raffles Place (The interchange logo is no different from Tanah
Merah / Jurong East)
The only nearest hint to your query is Vivocity, there was a
signboard that states the construction thing and a station map to
it, and from that, it seemed to suggest (NOT so clear) that, the
crossover before Harbourfront from Outram Park, is that, to connect
with CCL.(A bit stupid, I think they have screwed up everything +
waste tax payer's money) and IF that is true, then the existing NEL
platform A has to be "middle track" and not directly below it (It
IS directly NEXT to it)
I think I get what you mean. I've always believed that
interchanges with 1 white circle meant that we only have to cross
platform, or no need walk so much, while multiple circles like OTP
and DBG meant we had to walk to another mrt station.
Why would they have wanted to connect NEL to CCL? All the while
no link one what... 6-car vs 3 or 4-car (back then they havent
decided 3 or 4 yet i think)
Now that we're talking about HBF platforms, what is the reason
for platform B being so useless? I know its becos got no crossover
from OTP to HBF platform B, only after HBF... but why did they
build it like that? If there was no reason they might as well have
built one platform.
