Circle Line Stages 1 & 2

this is because the current Promenade platforms in service now has a Y-shaped split to serve both the CCLe and CCL1 towards Esplanade. and if the currently unused platforms are to serve CCLe, this makes the segment a level junction (see http://en.wikipedia.org/wiki/Level_junction), which LTA has been trying to avoid.
Well, it could be for the trains to change tracks. I'm not too sure about the signalling part, but they share Kim Chuan Depot's stabling area, which means the 2 lines' tracks meet in there. MTR's Tung Chung and Tseun Wan lines also use different signalling but the tracks are still linked.
But if the platforms will really never be used, why did they use wooden planks to cover it?

So you trying to say that the platforms behind those walls will never be used or what? What a waste.
CCLe is part of a greater "Stage 6" plan to become full circle, so it cannot be a shuttle using the unused platforms. not in the long run at least.
the most feasible plan now is when CCL becomes full circle. the dhoby ghaut to promenade stretch can then potentially form a new line terminating at promenade (since the platform end in a buffer at the unused platforms)
but promenade certainly is a weird place for a city terminus for any new rail line so I have no idea how LTA is going to modify their plans now.

Maybe is Dhoby Ghaut to Promenade shuttle?

well since the platforms are already built, I think it is better if LTA tries to plan a future line to use them than to really put it to death.
however this future line is very unlikely to be CCL or DTL.

personally I think it would be easier for everybody if trains terminate at Dhoby Ghaut and Marina Bay in alternating sequence till we move closer to full circle.

There is a tunnel to the right upon approaching the curve to Promenade from Esplanade. Terminal may be Bayfront or Marina Bay.

which platform does this tunnel look like it is leading to?
if it is really a future line, the Dhoby Ghaut to Promenade sector will be part of the new line and CCL will be a full circle (or run towards MRB and end in the meantime).

None, turn right across the river to Promenade lor lol. I put it in my diagram above already.

Paya Lebar cannot, the points are facing MacPherson only.

by river do you mean the active line between Promenade and Esplanade? sorry kinda dont get this part
I am referring to the "angle" the tunnel is turning out. does it look like it is joining the active or unused platforms?

Opps, i read the direction of your track diagram in reverse!

I think you got your perspective wrong haha. Okay, now we travel from Esplanade to Promenade, front view. The train starts to turn sharply to the left. At the start of the turn, there is a gap to the right. This is the tunnel I'm talking about. If you continue the turn, there's a green fence to your right and the empty trackbed on your left. Continue summore and you'll see the point towards Bayfront before entering the platform.

Sorry if this is a little off topic :D but recently i saw a very ambitious future subway MRT map and it consists of Bendemeer and Balestier on this blue line :S Anybody knows about it?

yup noted. so your guess is that it should now serve the CCLe shuttle?

Nope. My guess is that the tracks will be fitted in just before they open Stage 6 to have a Dhoby Ghaut - Somewhere shuttle. Not sure about the layout of Marina Bay and Bayfront so can't comment yet. Before that, it will be a Promenade - Marina Bay shuttle.

That map is a fake. However, what you are looking at is Downtown Line Stage 3 from Chinatown to Expo which is actually brown in colour.

then our guess is somewhat on the same page. I think it has the potential to be part of a future line that would most likely go beyond Dhoby Ghaut's buffers.
but this is definitely a deviation from original LTA plans so in a way, this segment is anybody's guess.

Okay, just finished redrawing the diagram. With a buffer at the end of the track, it should look something like this.
To the trained eye, you'll see that this idea makes no sense at all as the shuttle trains would have to either consolidate services to 1 level of the station, or have alternate trains arriving at alternate platforms (a la JEMP).
I have decided to extend the overrun to allow alighting on B3 and boarding on B2. This is to allow passengers going in the same direction ease of transfer. This might also be the actual case since the tunnel seems to turn left after Promenade. (Anyone with a video of the ride between Esplanade and Promenade can help me with this haha.)
This method is widely used in Hong Kong as most of the line's terminals are also interchanges.
With this, should Stage 6 pop up (HarbourFront to Dhoby Ghaut), the shuttle train going towards Dhoby Ghaut would go towards Bayfront and Marina Bay instead of Promenade as believed.
Sorry, even if that Stage 6 exists, it is only from Harbourfront to Promenade Via Marina Bay. This is because:
Fact 1: Dhoby Ghaut overrun is facing a dead end, in a direction towards Somerset (Based on the station map)
Fact 2: There is a NEL direct service plying from Harbourfront to Dhoby Ghaut, I dont see a need to do that again.

Oops, I typed wrongly lol. I wamted to type Promenade. No wonder as I was reading it, it didn't make sense the first time. I'll go change it now. Yeah Stage 6 is to make the Circle Line a complete circle.

This one makes for particularly interesting reading :
But I never comprehend on this map...... 我看�懂. Pai seh.

Oops sorry, I read it as Paya Lebar.
Tai Seng to Bartley, I only have a rough idea. But I think Samuel Lee has one.
Yes, I do, except between Stadium & Mountbatten, but the description is clear. (And of course exclude Bartley - Marymount -- If you guys really need, I may relook at the decision)
Read my beauty (art) world at BVE forum on CCL thread at here.

the currently unused platforms seem to be able to lead to Bayfront and Marina Bay if third rail and track is installed. this isnt confirmed and only rough estimation based on angle and it is still a dead-end right now anyway.
these unused platforms were however originally designed for Bukit Timah Line though so it is now anyone's guess whether it will lead to MRB (and eventually full circle via CCL6) or adapted for a future line use.

Based on your post, do you mean that the unused platforms seemed able to lead to CCLe, but from my observation during CCLD, it will involves a PMMP (Promendae Modification Project) to 2 points of existing tracks to become a slanted X shaped crossover or whatever it is called.
And by the way, I cant remember if it is Bukit Timah Line (The now DTL Stage 2) OR CCLE's original plan is to interchange with Nicoll Highway instead, but now is cramping everything in after the tradegy.

yes it seemed able to lead to CCLe, except it kind of doesnt make sense since the provisional tunnel looked like it is coming from an angle and not straight. but again I didnt manage to get a very close scrutiny on it thus I said I am not too sure.
IIRC Nicoll Highway is supposed to be Bukit Timah Line (DTL2) terminus and Promenade to serve Circle Line Downtown Extension (DTL1). so you are sorta right about the "cramming". it is also the cause of the uncertainty right now.
EDIT: after a little thought, the angle of the tunnel is just too weird. I suppose it is really part of some older plans. it doesnt even fit into the schematic below.
