Circle Line Stages 1 & 2

so anybody is going on sat morning for the first train for either side?

I got this off LTA's website, DTL section.

If this plan is not editted, the siding leads to DTL. How now?

this diagram isnt conclusive since it isnt a full-fledged technical schematic illustrating the routes of tunnels on both platforms. if we were to try and infer anything from here, it is that the current platform being used now has a Y-split. and the unused platforms have nothing.

in the schematic that I posted, the unused platforms are shown as empty with no tunnels running out of it. so where that tunnel leads remain unanswered. from its angle it may be a cross-track onto DTL but it is really just my guess. remember that this tunnel isnt designed for DTL nor CCL use right from the start.

and yes I understand trains from both lines can inter-operate if signals are compatible. the question now is we cannot confirm if CCL and DTL are using compatible signalling. if I have to make a guess again, I will say yes, reason being Alstom and ST Electronics, the turnkey contractor for CCL, will be doing E&M for DTL as well.

Notice something last train terminates at Mountbatten not Dhoby Ghaut.

They may be training on LTE or Evening Peak!!!

According to the 27 march straits times, they said it is to facilitate the transfer to DTL.

But based on my observation, i think that when ccl extension open, the dhoby ghaut to promenade route is just a shuttle. If u have noticed it, when the train departs for dbg, there is a track leading straight to a wall.

Dhoby Ghaut leg will become a spur shuttle unless govt goes on to link up HBF & Promenade into a real 'circle'.

Else it's unlikely a CCL Extn or CCL shuttle will occur.

maybe the CCLe becomes CCL stage 6 i guess

just that LTA names it CCLe at the beginning

Wow this is a complicated debate...

Here's my take after reading... According to Samuel, DTL is going to have a new platform and according to one of the plans I saw earlier, DTL is even lower than the current platform we saw during open house.

I conclude that the boarded up platform is for CCLe (or stage 6 I would too presume). I think so too because it was mention earlier that there are provisions for a 90 odd degree right turn from ESP to bayfront (This prolly answered my question about a branching segment i saw from ESP to Promenade on the right side.

And if this holds true, I think (just a guess) that running CCL would be like running the BPLRT. DBG to ESP is like CCK to Bukit Panjang (ESP is bukit panjang here) the lines split into 2 after ESP like service A and B, one gg to Bayfront while the other goes to Promenade.

As for the mysterious boarded up platform, could there be services that just run in a circle? (gg round the whole circle without gg to DBG via ESP) I'm just making this up as i go along. So this full circle thingy could be sort of a 3rd service.

Am I making any sense here? shoot me down if I'm talking gibberish =) But I do think that would be quite a feasible way to run the circle line as there are 3 different services to ply every direction.

Wow this is a complicated debate...

For continuous circle, trains will still use the current platform A & B because the unopened platforms have no link to Nicoll Highway station.

Which means a great probability for trains to/fro BayFront & Esplanande to share the current platforms A & B.

It is up to LTA to plan something out for the unopened platforms.

Able to picture the scenario at Tanah Merah when Changi Airport line ran to/fro Boon Lay? Probably that's the case.

Not really. I would read it as Harbourfront via (IF CCLe / Stage 6 is fully constructed as a full circle) Marina Bay via Bayfront is CCK then Promendae is BPJ. Dhoby Ghaut - ESP will be Ten Mile Junction. But there are certain things that is cannot be using BPLRT as direct comparison.

PS: It is not possible for Bayfront to turn to Esplandae without via Promendae, as there is no provisional crossover for that.

Look carefully when travelling from Esplanade to Promenade to your right just before the train turns left. It's a flat wall. Before that there's a green fence. No tracks yet, maybe no tunnels yet. But I'm sure there's a use for it. since it's quite odd for the tunnel wall to curve nicely away from the track.

Samuel Lee SG

O ya, the green fence. It is weird, but does that mean that the tunnel can be extended there? I doubt so, becoz, there is a wall blocking it, if I did not remember wrongly.

But if your theory is correct, then the unused platform will go straight, forming a slanted X crossover with current Circle Main Line, then heading a straight towards Bayfront or whatever, which is a running parallel as the current Promendae overrun.

Isn't that what I posted?

Samuel Lee SG

I see, I had misread the earlier diagram again. But I think that between the main line overrun and the parallel track's crossover will be done at somewhere further out of scale instead of too close to Promendae (Was that your second possibility?)

NickLim™ SG

It's a diagram. *facepalm* Not a geographically-accurate representation. Grr. In fact, I tried to make it so that the way the track turns can be visible to the untrained eye. Real track diagrams have no main lines running vertically, only horizontally and diagonally.

NOTE: Not to scale.

Anyone know why the EWL PYL Int announcement does not play "passengers who are continuing their journey on the Circle Line......." don't tell me they wait until CCL1 and 2 open 17 Apr 2010..

duh. play for what since its not open to public yet.

Samuel Lee SG

Obviously, I do know that is not drawn to scale. I think I have somewhat confused on the Possiblity 1 & 2 as on how to connect the lines.

PS: I am trying to say that, I personally, do not think that the either / or layout by NickLim is correct as it seriously will need a major change to the tracks, which I think the either or layout, will have the 3rd possiblity, which is neither, and they crossover at somewhere further on the right instead.

Oh thats quite a revelation... I didnt realise that. Erm would u know the station layout of Bayfront then? Stacked just like Promenade?

Some insight here... Lets say the continuous circle is a no go... Is it possible that both unopened platforms at PMD would travel in the SAME direction? just like the current and future NSL platforms at Jurong East? Having 2 platforms gg same direction just to ease traffic flow?

I have a new theory: CCL trains can only travel as 1 line, in 2 directions just like NSL. trains start from DBG, go down to promenade and then nicoll highway as per normal to cover the circle, basically in order from stages 1 to 5. Assuming the full circle, trains continue from HBF to MRB to Bayfront and ultimately terminate at Promenade (unopened platforms).

The second direction is exactly opposite, starting from both unopened platforms assuming my same direction idea holds true, now going clockwise to eventually end at DBG.

Food for thought. =) I think this is quite a cool idea though haha! Wonder if it works...
