Preparations for Circle Line Stage 6
-
Well, I learnt about them from various source such as rail forum and Wikipedia.
If it's confirmed that SMRT is operator for DTL, I can safely say that CCL and DTL will share train like NSL and EWL unless DTL depot is being built, then DTL will probably have their own train.
As for train model and design on DTL, I don't have the information so I can't give you the answer on this. But I am sure that the manufacturer for DTL train is still Alstom as Alstom has specialization in building driverless train.
I remembered somewhere that it was mentioned DTL depot will be built along DTL Stage 3 as the available land along DTL Stage 2 is reserved for residential development or some other developments in which land resource has to be planned and optimized. But I can tell you it's still under planning and is not confirmed yet. Who will know if they have decided to build depot along Stage 2... So just wait and see for latest news from LTA.

Circle Line to exceed original budget of $6.8b
14 September 2007 1535 hrs (SST) 0735 hrs (GMT)
SINGAPORE: The Circle Line MRT project will exceed its projected $6.8 billion budget.
But this increase is unlikely to be more than 10 percent of the original cost, according to the Land Transport Authority's estimate.
The costlier project is due to the disruption in the supply of sand and granite faced by the construction industry recently.
Aside from costs, LTA says the Circle Line project is on schedule.
At the Farrer Road and the Botanic Gardens MRT construction sites, work is well underway to beef up the stations' structural frame.
There are 10 stations in the permanent works stage which involves laying the foundation and putting up critical support structures.
At the Botanic Gardens station, 192,000 cubic metres of earth have been excavated. It will use some 54,000 cubic metres of concrete. This process takes roughly 18 months.
But other stations are even nearer to completion, with just the finishing touches to go.
In fact by the end of the year, LTA will hand over the first four completed stations to operator SMRT. These include the Dhoby Ghaut, Bras Basah, Esplanade and Promenade stations.
SMRT will oversee caretaking duties leading up to the Circle Line's operational date of 2010.
Lim Bok Ngam, LTA's deputy chief executive for infrastructure and development, said: "Overall, the Circle Line is about 65 percent completed. For individual elements, tunnelling works, we are about 70 percent completed. On the station side, I think 10 of the 29 stations are already into the architectural and fitting up work phase."
LTA had to grapple with cost issues arising from the recent disruption in sand and granite supplies.
The agency will compensate its contractors 75 percent of the increase in sand and granite costs. The increase in costs has affected phases 4 and 5 of the project.
LTA's Mr Lim said: "The few stations and the Circle Line 2, for example Nicoll Highway, Dakota, Mountbatten, they're also affected. But contractors are working closely with us, there's no big concern about supply."
LTA says it will not know the final increased cost of the project until it is completed. For now, it says, it will be able to manage the situation. - CNA/ir -
Bishan PSD picture taken by tamago
That is taken on the parts of platform which is at between 1st and 3rd car of train on SB towards the driver's front cabin.
The backmost parts of platform (between 5th car and 6th car of a train) are now being built and PSD metal will be installed soon, following by the center parts of the platform which has yet to be built. -
i recently passed by some parts of CCL stage 2 and i couldnt help noticing that there are stage 3 stations that are more completed than some stage 2 ones...
if i'm not wrong, Tai Seng (former Upper Paya Lebar) has station exits all done up and ready, jus like stage 1 stations, but Macpherson, which is just before Tai Seng, still has a long way to go. I think i can safely say that Serangoon station has progressed faster than Macpherson...
btw Tamago thanks for the pics... didnt expect the construction to be so fast... -
Alstom trains that good meh? from the NEL the braking seems lousier than the Kawasakis and Siemen ones... thought it can accelerate faster, the braking takes quite long lei... or isit sbs programmed it to take longer time to stop?Originally posted by Novawin™:As for train model and design on DTL, I don't have the information so I can't give you the answer on this. But I am sure that the manufacturer for DTL train is still Alstom as Alstom has specialization in building driverless train.
and i'm curious to know... if i'm not wrong, the high pitch screeching during braking indicates wear and tear of braking system right?
i notice NEL's train brakes produce much more screeches than those on NSL/EWL... Are the brakes on Alstom trains really bad or is it because of the autopilot? cos i notice the BPLRT also got screeching... -
I don't mean to say that Alstom is good. I have not seen Kawasaki and Siemens ever building driverless train before. Or perhaps they lost to Alstom during LTA's tender process to build driverless train? You can enlighten me more with this information if you have any on whether Kawasaki or Siemens are able to manufacture driverless train.Originally posted by SMRT 32373238:Alstom trains that good meh? from the NEL the braking seems lousier than the Kawasakis and Siemen ones... thought it can accelerate faster, the braking takes quite long lei... or isit sbs programmed it to take longer time to stop?

You are right, that's why I said earlier that Stage 3 construction is fastest. Serangoon station will be completed early before MacPherson station.Originally posted by SMRT 32373238:i recently passed by some parts of CCL stage 2 and i couldnt help noticing that there are stage 3 stations that are more completed than some stage 2 ones...

By the way, Channel 8 news showed several completed CCL station that evening just now. Will upload the pictures soon. -

wow nice! thanks haha i hardly watch tv...
those are probably stage 2 stations right? cos they look very NEL-lish in design haha most of the stage 1 stations have unique outlooks... -
Yup, they are Stage 2 stations. For the first picture, I not sure which station is this one. For second and third picture above, this is Dakota station.Originally posted by SMRT 32373238:wow nice! thanks haha i hardly watch tv...

I think the first picture should be from Tai Seng station. Tai Seng has been ready for several months now. The empty section at the side of the wall in between the two escalators also matches the description for the art work by LTA.

CONSTRUCTION WORK ON SCHEDULE, BUT...
Circle Line will exceed $6.7b budget
By Christopher Tan
CONSTRUCTION work on the Circle Line MRT is on schedule, but it will cost more than the original $6.7 billion budgeted.
Inflation, more expensive concrete and more stringent design and engineering standards following the 2004 collapse at the Nicoll Highway station have pushed costs up.
Giving a progress report yesterday, Land Transport Authority deputy chief executive Lim Bok Ngam said part of the 33.5-km line should be ready by 2010, with the rest of it completed by '2011 or 2012'.
The new timeline takes into account delays after the 2004 collapse. Before the accident, which killed four workers, the first phase of the line was to have been completed by 2006, and the second phase by 2010.
Yesterday, Mr Lim said: 'In all mega projects, there will be some areas of works that are ahead of schedule and some slightly behind. For the Circle Line, we are satisfied that the overall progress is on track for completion from 2010.'
About 65 per cent of the line has been completed.
The structures of 14 of the 29 stations are done, and by next year, LTA expects all tunnelling work to be finished.
The Circle Line, which is expected to carry 400,000 to 500,000 commuters daily around the city centre, may yet open in stages.
The LTA said that a stretch measuring about 8km - with seven stations between MacPherson and Marymount - was in advanced stages of completion.
In fact, architectural, electrical and mechanical works are being carried out now, and are expected to be completed by mid-2008.
The Straits Times understands that as the train depot is along the stretch, it is feasible to open it as early as the first half of 2010.
But Mr Lim would not commit to this.
'It's not just the construction. Testing and commissioning of the system can be quite complicated,' he said.
Mr Lim said a new contractor will soon be picked to finish the MacPherson and Tai Seng stations - where construction stalled last year when Sweden's NCC stopped work because of the sharp rise in concrete prices.
Mr Lim said another episode such as this was unlikely, saying 'the NCC case was an exceptional case'.
Industry players said NCC, a relative newcomer to LTA work, may be the first casualty of cost overruns which have hit Circle Line projects since the 2004 collapse.
The Nicoll Highway station has been re-designed. It is now one-third smaller, but costs 10 per cent more to build.
Higher engineering standards - which have pushed up costs - were evident at other stations along the line.
For instance, the Farrer Road Station under construction now has retaining walls that are 1.2m thick - 50 per cent thicker than the collapsed walls of the Nicoll Highway station.
The higher standards affect the western half of the Circle Line more, as construction there started well after 2004.
Mr Lim said the eventual cost 'has not been worked out', but the higher cost of sand and granite would only add 'a single-digit' percentage increase to the project.
He said the LTA will compensate the contractors 75 per cent of the rise in sand and aggregate cost.

yeah!!!!!!!
I checked Chinese CNA (Channel newsasia) and it names the 10 stations with completed structures!!!
They are:
Dhoby Ghaut, Bras Basah, Esplanade, Promenade, Stadium, Macpherson, Tai Seng, Bartley, Serangoon, Lorong Chuan, Bishan, Marymount, One north and Harbourfront.
and it has a nice pic:

Helping you to show image instead of putting up a link.
Since yesterday's news mentioned about 65% of tunneling works for overall CCL are completed, Stage 3 construction seemed to be fully completed. But too bad, CCL only open on 2010 along together with Stage 1 and 2. -
the opening will be earliest 2010 meh? do they really have to wait for nicoll highway to open 2 and 3 together with the rest of stage 1? cant they open 2 and 3 first?
i thought macpherson was still quite screwed up... well from the outside at least... -
Even if they want to open just Stage 2 and 3, it'll still be 2010.
-
Supposedly, Stage 2 and Stage 3 could be opened by late 2008. However, LTA mentioned they only can open CCL Stage 2 and Stage 3 on 2010 with Stage 1 as soon as Nicoll Highway construction is done.
Even if Stage 2 construction is completed and is ready for service before 2010, still have to wait for Nicoll Highway station and tunnel construction to be completed.
And I think MacPherson got another station box meant for future DTL as I read somewhere that provision has been made to CCL MacPherson station during construction for interchanging with DTL Stage 3. -
New doors have arrived!
As of today, Bishan SB New Platform was spotted with 5 new sets of doors... picture will be taken the next time.
Or you can visit it yourself.
It's exactly the same design from that of NEL PSDs, so I guess other CCL stations are tendered from the same PSD manufacturer. -
1. Alstom trains are programmed to brake by the Main Control Centre in Sengkang.Originally posted by SMRT 32373238:Alstom trains that good meh? from the NEL the braking seems lousier than the Kawasakis and Siemen ones... thought it can accelerate faster, the braking takes quite long lei... or isit sbs programmed it to take longer time to stop?

2. The longer braking time actually helps prevent wear and tear as friction is applied slowly instead of all at a shot in SMRT trains.
3. Yes, the high pitch frequency of the brakes will spoil them because the brakes used by Alstom suck. o_O -
CCL trains stations follow designs that of NEL.Originally posted by Novawin™:Yup, they are Stage 2 stations. For the first picture, I not sure which station is this one. For second and third picture above, this is Dakota station.
Even PSDs are same (I'll take picture next time though) -
i'm quite sure stage1 stations are more unique... well not the PSDs la but at least the layout...Originally posted by Oceane:CCL trains stations follow designs that of NEL.

if its like that, why isit that new trains are purchased from Alstom instead of Kawasaki? i think the Kawasaki ones, especially SMRT's 3rd gens are the best... its quite smooth and silent too...Originally posted by Oceane:1.

well, since they are using different systems. for SMRT, buying siemens seemed like a mistake. it was loud, and had certain incompatibility issues from wat i observe. going back to KHI was probably best.Originally posted by SMRT 32373238:if its like that, why isit that new trains are purchased from Alstom instead of Kawasaki? i think the Kawasaki ones, especially SMRT's 3rd gens are the best... its quite smooth and silent too...
for alstom, they have a proven record in singapore of delivering turnkey solutions for driverless metro, as seen from NEL. and they had to do everything from control interfaces to signalling to trains. -
All PSD on NSL, EWL, NEL and CCL are manufactured by same PSD manufacturer, Westinghouse.
Therefore, CCL PSD will sport the same layout and looks as NEL PSD.
