-- BBT -- BGK -- CCK - (sub) -- YWT -- .....
there are substation like some u see between DVR and CLE under the railway viaduct. even myself saw it at a few metres away from CNG.
let say if UPD off the sub at CNG..
... -- DVR - (sub) -- CLE -- UPD -- JUR -- CNG - (sub/off) - LKS -- BNL -- PNR -- JKN
-- BBT -- BGK -- CCK - (sub) -- YWT -- .....
Trains can run until jurong east and thru NSL.. the effected area cannot run because the sub is off..
another example.. UPD wanna switch off at CCK
-- DVR - (sub) -- CLE -- UPD -- JUR -- CNG - (sub) - LKS -- BNL -- PNR -- JKN
-- BBT -- BGK -- CCK - (sub/off) -- YWT -- .....
trains can't run along BBT and BGK but CCK as terminal, CCK can run 1 crossover..
thus if UPD wanna switch of these 2 subs..
-- DVR - (sub) -- CLE -- UPD -- JUR -- CNG - (sub/off) - LKS -- BNL -- PNR -- JKN
-- BBT -- BGK -- CCK - (sub/off) -- YWT -- .....
can train running from Lakeside to Joo Koon??Good insight into the substations. Glad someone is on the same channel.
Adding on there are actually station-situated substations, especially at Jurong East and Bukit Batok, which feed the system. In fact we have so many substations for electricity that our system does not suffer from current drop like many other DC systems.
Additionally there is one substation between Choa Chu Kang and Bukit Gombak, slightly opposite of Swiss Cottage Secondary.
However the decision to stop the usage of even Bukit Gombak (despite having a switch after BGB towards BBT) is more of a operational concern more than technical constraint (no proper bus terminal). This is my personal insight, not company's.
The closure of the tracks would actually be more towards the switch and signal installation operation than third rail; electricity can be varied to cut off at certain sections before the work zone hence this is not the main/most important reason. And of course, the ability to maintain service frequency at non-affected areas, the fastest way to turn trains around is important.

Yes. Just to know: After Raffles Place there is a 1 turn (from Raffles Place to City Hall), EB to NB; SB to WB.
Off-service trains may go from Bukit Gombak, all the way via Raffles Place to Clementi, and then go to UPD.

Yeah the EB to NB, that crossover is directly right after the station

I've considered this also. But I don't think fresh trains will appear in City Hall, pretty unlikely.

BSD 46 trains to supply to NSL, so no need to worry from UPD.
Usually UPD supply the most number of trains. Thats y u will see it empty -

If really BSD can store 53 trains instead of current 46, then it means that UPD will be fully closed (Probably the substation is closed) and this will take place:
A) 18 of the 35 UPD trains are going for a "long vacation" (Actually 2 weekends la)
B) 7 of the 30 UPD trains will be deployed into BSD (53 - 46 = 7)
C) 10 of the 30 UPD trains will be deployed into CHD (40 - 30 = 10)
Well, since a large sector of EWL is affected, then they might not even need that much trains in the first place.
By the way, I would like to ask, if they built a substation in Pioneer or Joo Koon during BLE construction, then is it possible for a Lakeside - Joo Koon shuttle service or still only a Joo Koon - Boon Lay shuttle service in theory?
By the way, can somebody count the number of yellow train cars SMRT has such that IF they deploy 2 yellow cars to attach on each train's end, is it possible to run shuttle train service without relying on 3rd rail? (And of course if someone managed to view the TO cabin, inside got nobody one because the depot staffs / TO drive the yellow car thing). If that is possible in theory (even if they do not have sufficient yellow cars to implement my earlier suggestion, will that affect PSDs open close door as well IF JEMP takes place at 2012 or later) -- another theory question.

The yellow thingy, I don't think it'll be strong enough, and also fast enough, to be able to shuttle service.
If there's this shuttle service with this thing, it could only go for 15km/h at most. I'd rather have bus shuttle service instead.

I only see one maintainance truck couple with another by accident =P (Or should I say, they don't have couplers on both side, only 1 side)

the closure is due to the tracks, not because of the service, as you know that JEMP has 2 additional tracks, there is a need to be a switch somewhere near JE so that it can be installed and maybe intergrated to the existing lines
besides how to check if it s working fine w/o putting it to test first?? night time don't tell much , day time theres the routine service running by, so no choice, close the area to check for daytime issues and maybe defects, thats is what i think that is ongoing now and later, it would also explain why the services near or at Jurong east is affected.

What 2 additional tracks? JEMP adds a new platform and splits into 2 tracks as one is for trains from Bukit Batok and the other is towards Bukit Batok. Well, all these are in the EB side and that does NOT affect the WB side and in theory, it should be safe for 1 train to ply bi-direction from Clementi - Jurong East and Jurong East - Lakeside WITHOUT considering the substation issue yet. Regarding NSL, even the one FROM Bukit Batok, the track split is located at the point of Morning peak hour / NSL -> EWL crossover track and not on the main line itself, and if I am not wrong while the one towards Bukit Batok track connects onto the existing towards Bukit Batok track. Hence, it means that the From Bukit Batok track can again become a bi-directional shuttle service with a maximum of 1 train plying the service on Bukit Gombak - Jurong East, of course, without consider on the substation issue.
Of course, you may argue that the safety issue and any trains that come onto Jurong East may endanger the workers, hence, it might make sense on Lakeside - Joo Koon and Bukit Gombak replaces Jurong East as the terminus.
Dunno where can I feedback this suggestion leh.

Yes.. maybe UPD will switch off the BGK Substation but will on the CCK sub.. thus train can run until CCK only -
Hi there, these are the photos i took today

nice... anyway that means for EWL is trains from/towards PSR will terminate at Clementi & for NSL from/towards MArina Bay will terminate at CCK bah?

Train services disruptions expected in September
By Dylan Loh | Posted: 18 August 2010 1108 hrs
SINGAPORE: There will be disruptions to train services in September when the Land Transport Authority (LTA) carries out track modification works at the Jurong East MRT Station.
There will be no train services between the Jurong East and Clementi Stations on September 4 and 5.
Also, there will be no train services on September 18 and 19 between the Jurong East and Bukit Batok Stations.
LTA and SMRT will be providing free bus bridging services to ferry commuters between the affected stations during disruptions which will occur during weekends.
They have advised commuters to plan ahead for their journeys, to factor in the additional time needed to transfer from the train to bus, and vice versa.
The LTA said it has also been working closely with grassroots leaders to inform the community in affected areas of the service disruptions and of alternative transport options. - CNA/vmI bet that
On September 4 & 5:
PSR - CLE (Main line normal service, wow 1980s, I was not even born then), JKN - LKS (6 ~ 10 trains shuttle train?), LKS - CNG (1 shuttle train or 2, but at most 1 train at each platform --- Amazing!).
On September 18 and 19:
MRB - BGB (Main line normal service, wow never once with such arrangement.), BGB - BBT (1 shuttle train or 2, but at most 1 train at each platform --- Amazing!).

Train capacity to expand, waiting time shortened
JEMP works to complete by 2011

channel 5 news just said that je mrt station will be closed due to jemp...

So the article is correct.
