Why MRT cannot have 1 min interval like hong kong?
-
I have been to Hong Kong recently and find that HK MTR interval for each train is < 1 min during peak hour. Although is very crowded, ppl will queue orderly for the next train because they know that after one min, the next train will arrive.
-
MTR got so many lines, so many trains, obviously they can rule out the one minute interval.Perhaps you haven't see the 1 minute interval for Singapore, the next train have to wait for the train at the station to leave then the waiting one can enter. You think it's so easy for SMRT to rule out one-minute intervals? Wait long long.
66 C151 - EWL/NSL
19 C651 - EWL/NSL
21 C751B - EWL/NSL
21 C151A - EWL/NSL
40-1 C830 - CCL
25 C751A - NEL
73 C951 - DTLTotal is 264 trains, and it is only with effect of year 2012.
And i think you have heard of what bunching means right. You will not expect one train come damn full next train about 30seconds behind empty empty.

Because "queue orderly" and "Singaporeans" are two terms that never go into the same sentence without a "don't" in between them?
Seriously though, the only time that there is ever a one-minute frequency is when there are delays that cause back-ups, resulting in the next train being just hundreds of meters away from the first one. There probably can be one-minute intervals, but it's just not going to happen with the people in charge.
I wrote to LTA a few years ago regarding this subject, and they gave me some crap about the number of trains and how only some trains are compatible for rush hour service.

Damn lot of reasons. I will list down later.

Simple.Coz' HK's got a much higher population and thus more demand.Vice versa for SG.
And if it is crowded it will take abt 3-5 mins to get to the door.so i don't see much difference. -
Easy to say,Hong Kong is larger than Singapore.The bigger the country,the bigger the population.
-
cos SG what.. here public transportation is about packing as much ppl as possible in each train to maximise the profit lor..... who cares about 1 min interval?
-
Because hong kong is bigger than singapore, if singapore mrt have 1min intervals, there will be traffic jam, and we all don't like that.

are compatible for rush hour service. When there is 1 minute internal, who will still rush into the trains without letting people going out first? Then all these queue orderly will be gone.
And who said Singaporeans don't queue orderly?

do a search in google

nid to upgrade e signal system first
but ironically, pui... MTR is BOT project, service so much better than SMRT who does not nid to spend a single cent on e infrastructure.

We can hv 1 min interval, having more trains mean need to pay more fare.
-
well other thn train bunching problems, our track signalling system does not support train to be kept 1 min apart. hence its quite impossible to do 1 min interval. Its lyk trying to make ur com run at 2.4GHz speed when it is only 1.66GHz.

MTR Peak: 30-45 seconds
MRT Peak: 1-2 minutes
MTR Non Peak: 3-4 minutes
MRT Non Peak: 6-8 minutesMTR Fleet (Urban Lines) currently: 99 M-Trains + 13 K-Trains = 112 Trains
MRT Fleet (Main Lines) currently: 66 C151s + 19 C651s + 21 C751Bs = 106 TrainsMTR Total Length (Urban Lines): 13.3km (ISL) + 14.7km (KTL) + 16km (TWL) + 12.3km (TKOL) = 56.3km
MRT Total Length (Main Lines): 44km (NSL) + 49.2km (EWL) = 93.2kmTherefore, MTR has more trains to cope with shorter distances, and MRT has less trains to cope with longer distances. It may be due to the lack of trains to remove short working trips and add full trips.

Well justification and eloboration of the problem.
You score a 10/10 for this essay question

Even though MRT has lesser trains, you will still quite a number camping at depots.
MRT Peak: ~28sec from door open to close
MTR Peak: ~57sec from door open to close
So probably MTR is actually roughly 2mins/train.
So, LETS SEE if SMRT can do 2min/train.

Here are some of the reasons why you won't get to see a consistent 2 mins per train frequency:
1. We are currently facing "train shortage".
2. SMRT & LTA prefers to have the system to perform at it's optimum (24tph), rather than at it's maximum (28~30tph).
3. Normal Mode and Fast Mode Exist in Auto Mode. A train coasting @ 40~60km/h is not utilizing every seconds. When accumulated enough over time, it will have sufficient headway to allows an extra train to be placed into the system for revenue service.
4. Inefficient schedule. Trains are given too much time to travel in between stations. (See point 4)
5. Schedule of train's frequencies are inconsistent.Train C <--5 mins frequency--> Train B <--2 mins frequency--> Train A
6. During CM, performance of system decrease as TO are not trained well enough to operate a train as well as a computer.
7. Automatic system has it's constraints and because of these constraints, multiple redundant failsafe mechanism are required to prevent an accident/incident from occuring. These failsafe mechanism decreases the maximum performance acheivable when compared to a system where trains are driven manually.Train congestion, is acceptable as long as there is no more than one train stopped completely waiting for the front train to clear. This problem can be minimized by enforcing effective & efficient scheduling of train as well as "dwell time abuse".
When the system are pushed to it's maximum:
North-South/East-West Line: 45~70 seconds (6-car formation) (ATC-4)
Keikyu: 0~30 seconds (4,6,8, 12-car formation) (C-ATS)
Keio: 15~24 seconds (10-car formation) (ATS-S)
Yamanote: 25~30 seconds (11-car formation) (D-ATC)Frequencies given above are obtained by having the timer:
- Start: The moment the train starts to move off
- Stop: Front-end of the train behind touches the back end of the platformAs different train system has different no.-of-car/train length, it's unfair to determine frequency by:
- Timer start when train totally cleared station, timer stop when train behind made a complete stop in station
- Timer start when the moment the train starts to moves off, timer stop when train behind made a complete stop in station
- Timer start when train has totally cleared the station, timer stop when front end of the train touches the back end of the platform -
1 min per train interval = only in HK island lei....
yes... very effective

No, all the urban lines get the same frequency.

I do agreed with u (in urban areas)... been to Tung Chung lately (end of the yellow line) .. waited for almost 5 mins...
for a return trip back to Kowloon...The most effective is the island line ... dun have to rush to catch a MTR...

hey hk girls more chio or sg girls more chio?heard that hk girls skin is fairer and nicer rite

HKMTR signal system is more efficient than Singapore's signal system. Please understand that.

why cant sg emulate hk signal system then, just like china learn from us. -

TCL and AEL has frequency equal to our CGL. 12 mins during off peak and 4 mins during peak.

Last night, it was also clamp (9pm+).
