MRT Circle Line Phase 4 and 5 Announced!

What about from Orchard straight to Tiong Bahru Station, stopping at Great World City in between?Originally posted by ^tamago^:The rationale of not building a ORC-OTP link is because the cost of building such a short link does not justify the savings in travel time. Neglecting waiting time before boarding, but including waiting time for transfer at either RFP or NEL, the travel times are as follows:
NSL-EWL: 11-17 mins
NSL-NEL: 11-17.5 mins
ORC-OTP (with 2 stops in between): 7 mins
BUS: 13 mins
Saving just a maximum of 10 minutes at (my) estimated cost of $1-1.2bn (for fully underground) is not worth it. Also, engineering difficulties at OTP with 3 stations interchanging is also another major problem. -
1. Tiong Bahru station has no space for an interchange.Originally posted by disappear:What about from Orchard straight to Tiong Bahru Station, stopping at Great World City in between?
2. Between Great World City and Outram Park, the route alignment is basically a straight line; while to Tiong Bahru, there will be a right turn. -
It is pointless to duplicate EWL for one station. Anyway, if it were to come to fruition, it would probably be a LRT line.Originally posted by tranquilice:1. Tiong Bahru station has no space for an interchange.

it is also possible for viaducts to be constructed. but i was suggesting that there is impossibility of having a tunnel, if any, as near as Jurong West Street 63. but building subways save precious land in Singapore, and make it easier to articulate in the industrial estate.Originally posted by tranquilice:Why is there a need for a tunnel after Pioneer Rd North, as viaducts can be build along Upp Jurong Rd.
i was at the site today and i realised that the MCP will have to be removed to extend the line. judging from the way NSL was extended from YSH and CCK ends, they dun seem to like to remove the end viaducts, probably for the purpose of holding trains there (i've seen such an incident at PSR before). but if they dun wan to remove the MCP they'll have to realign the whole end viaduct along Jurong West Street 63. But no tunnels there, i suppose. -
The proposal for the tunnels along St 63 came about because some people were suggesting that the area does not have enough space for the construction of viaducts.Originally posted by ^tamago^:it is also possible for viaducts to be constructed. but i was suggesting that there is impossibility of having a tunnel, if any, as near as Jurong West Street 63. but building subways save precious land in Singapore, and make it easier to articulate in the industrial estate.

If building viaduct is not a problem at all, then tunnels will not be necessary. It has already been announced that the extension will be elevated. -
i didn't read the announcement about the elevated part. anyway i was having the idea that subway could provide more manoeuverability in route of the line.Originally posted by kenmin:The proposal for the tunnels along St 63 came about because some people were suggesting that the area does not have enough space for the construction of viaducts.
If building viaduct is not a problem at all, then tunnels will not be necessary. It has already been announced that the extension will be elevated. -
If it is to be elevated the only logical way then is to build the viaduct over the MSCP or above St 63, which would involve realigning the tracks.Originally posted by kenmin:The proposal for the tunnels along St 63 came about because some people were suggesting that the area does not have enough space for the construction of viaducts.

Its not possible to build it over the MSCP.. The MSCP will have to go.. pls do your research before you make a firm statement.Originally posted by SBS9818A:If it is to be elevated the only logical way then is to build the viaduct over the MSCP or above St 63, which would involve realigning the tracks.
-
actually, there's no space for the viaduct to go higher above the MSCP, assuming that it will be so.. i believe the viaduct will be realigned instead of having the MSCP torn down, as the viaduct will have to make a weird S-turn to move onto the divider of Jurong West St 63.. it is more logical to follow the alignment of the road right from Boon Lay station..

Yes, most probably a LRT line, I expect demand will not be high.Originally posted by SBS9818A:It is pointless to duplicate EWL for one station. Anyway, if it were to come to fruition, it would probably be a LRT line. -
I expect the MSCP to go. I have also seen before trains parking at the end viaduct. As for the limited space outside the foodcourt (3rd bus stop from interchange), I guess the viaduct has to be aligned to the central divider.Originally posted by ^tamago^:it is also possible for viaducts to be constructed. but i was suggesting that there is impossibility of having a tunnel, if any, as near as Jurong West Street 63. but building subways save precious land in Singapore, and make it easier to articulate in the industrial estate.

There is no way for the viaduct to be build over (on top of) the MSCP, as the height of MSCP is higher than the end viaduct.Originally posted by SBS9818A:If it is to be elevated the only logical way then is to build the viaduct over the MSCP or above St 63, which would involve realigning the tracks. -
I think the end viaduct will stay, it is important that the trains still have some distances to stop in case they over-run the station.Originally posted by ^tamago^:actually, there's no space for the viaduct to go higher above the MSCP, assuming that it will be so.. i believe the viaduct will be realigned instead of having the MSCP torn down, as the viaduct will have to make a weird S-turn to move onto the divider of Jurong West St 63.. it is more logical to follow the alignment of the road right from Boon Lay station.. -
That explains the excess track at the ends of PSR BNL MRB PNG and CGAOriginally posted by tranquilice:I think the end viaduct will stay, it is important that the trains still have some distances to stop in case they over-run the station. -
Aiya, I care so much for what? Doesn't affect my carpark lot what.Originally posted by service_238:Its not possible to build it over the MSCP.. The MSCP will have to go.. pls do your research before you make a firm statement. -
HBF has 3 tracks (incl. an overrun tunnel) at its end.. as for MRB, it does not look like it has excess tracks to fill another train inside.. there is this point: does the end viaducts at BNL need to accomodate a whole train or jus to provide some excess track? if not, part of the viaduct can be realigned along Jurong West St 63.. i've only seen a whole train parked in the end viaduct at PSR, and i suppose tat's a rare case..Originally posted by service_238:That explains the excess track at the ends of PSR BNL MRB PGL and CGA -
I'm curious how come you know there's 3 tracks beyond HarbourFront station.Originally posted by ^tamago^:HBF has 3 tracks (incl. an overrun tunnel) at its end.. as for MRB, it does not look like it has excess tracks to fill another train inside.. there is this point: does the end viaducts at BNL need to accomodate a whole train or jus to provide some excess track? if not, part of the viaduct can be realigned along Jurong West St 63.. i've only seen a whole train parked in the end viaduct at PSR, and i suppose tat's a rare case..
The end viaducts beyond Boon Lay station need to accomodate a whole train, for unknown reasons. I have seen trains parked there at both Boon Lay and Pasir Ris. -
the SBST staff told me on the first day of operations (20/6/03). in fact, some even had the chance to go inside the overrun tunnels. but they usually dun allow cos they are afraid the train may get jammed inside then they have to evacuate passengers.Originally posted by tranquilice:I'm curious how come you know there's 3 tracks beyond HarbourFront station.

the train on reaching Platform B will turn right into overrun (middle) tunnel, then reverse back onto Platform A, if it ever goes beyond HBF. -
That's interesting. The overrun track has been used at least once before for trains to switch tracks instead of doing it the SMRT way.Originally posted by ^tamago^:the SBST staff told me on the first day of operations (20/6/03). in fact, some even had the chance to go inside the overrun tunnels. but they usually dun allow cos they are afraid the train may get jammed inside then they have to evacuate passengers.

Is the overrun tunnel like the one near Outram Park station?Originally posted by ^tamago^:the SBST staff told me on the first day of operations (20/6/03). in fact, some even had the chance to go inside the overrun tunnels. but they usually dun allow cos they are afraid the train may get jammed inside then they have to evacuate passengers.

For everyone's information...Originally posted by tranquilice:I'm curious how come you know there's 3 tracks beyond HarbourFront station.
Berita Harian published a full-page, full-coloured graphics report on the construction of HarbourFront Interchange, sometime in 2002 if I'm not mistaken. I still have the report.
Cheers and warm regards -
Hi everyone. I see that there are three types of trains currently in service with SMRT- the older trains, slighly newer trains with greener windows( a e-orh, e-orh sound can be heard when stopping) and the newest trains with the upper portion painted in black. Which is the siemens model and kawasaki model?
Are they still getting the newest trains after the gear box problem about two years ago? -
Kawasaki ones are the oldest one, Siemens are the one in the middle..Originally posted by eurofighter:Hi everyone.

The one with green windows are the Siemens ones. The new Kawasaki trains (black windows) are used only for peak hours now.Originally posted by eurofighter:Hi everyone.
