How come morning train alway like that one ....
-
I recently started to take train to school at habourfront every morning
i usually go out very early , so no problem
but these few day , i go out a bit later
and i reach otram station at arounf 7 - 7.20 am where the train is alway VERY crowded.
That alright , but people haven finish going out the train start making the annoucement that door is closing. people haven entered the train , the door already closed.
on 1st attemp , most people had alighted , i was about to board the train and the door immediately closed , i was almost get caught in between the doors , i missed the train
another incident , people just alight , i learn my lesson , i squeeze my way in before door close , but this man also wait for all people alight then board ,but the door closing, he hop in and his suitcase stuck by door , door was reopen and closed
My point here is that , why the rush since outram park to habourfront only 1 stop away ? people haven start boarding the door already closing -
Bcos if they hav to wait for all ppl to onboard..
den the door can perm. open down there..
another tink is, as u know its peak-hr..
so the frequency for e train to arrive is very fast -
I dun like North East Line because it sucks!
The train doors will not open immediately after the train stops and passengers have to wait the stupid computer to do its calculation (4-5 seconds ) for the opening of the doors.
The NEL Train is like wad you mentioned, very inconsiderate and not understanding to passengers. The train doors can suddenly close even there were passengers still boarding.
In addition, I have noticed many platform LCD Plasma TV that shows Train timing are faulty and POOR train timing information given, unlike NSL and EWL.
SBS has done such a poor job. SMRT did better than SBS. -
but like that dangerous leh , i seen so many time and im not the only that that got stuck by the train , seen so many ppl got leg stuck , ppl go in bag stuck on door wateverOriginally posted by a-Lost-9uY:Bcos if they hav to wait for all ppl to onboard..

if were to happen ardy happened leh..

One reason is because , mrt have operators manning the train and running it but NEL is fully computerised unless it breaks down then will ask operator to run it . Mrt the operature can see the passenger flows in real life while NEL depends on traffic controllers to check using cctv from site .As long as theres nothing wrong they will let it run by its own computers . Not to mention you all i once board their lrt with a strong shit smell and even have traces of shit inside .

Well, the new WestingHouse doors are slower to open even for SMRT's case (see Changi Airport Stn), but Alstom's trains also does its own checks to ensure the correct alignment thus the delay becomes significant.Originally posted by MsSwanLover:I dun like North East Line because it sucks!

the arrival timing is also quite hugely based on scheduling rather than updating the location of the train.
when there's a disruption the timings have to be manually given or a notice displaying indicating a rough interval. SMRT's timings are based more on train location and the train can indicate back to backend if it is delayed and its schedule has since changed. in fact SMRT follows more on japanese standards, accuracy to 15 secs, and they set their speed nicely. very good. -
Dun say NEL
SMRT one also... @ Orchard always kena
so many ppl haven't board, train officer close the door liao -
sori, me dun take train de.

Well, one thing is the train can't stop at a station for too long because it would mess up the accuracy of the schedule. Accuracy is VERY IMPORTANT during peak hours because it affects the number of passengers boarding a train. Assuming X passengers arrive at the station to board the train every minute, every extra minute contributed for the waiting for passengers to board in the previous station would lead to an extra of X multiplied by number of minutes.Originally posted by Unidentified:I recently started to take train to school at habourfront every morning

As far as I know, PSDs have sensors installed so as to not KIAP people when the doors are closing. As long as the doors close onto somebody, it would reopen. However I suggest that passengers not to abuse the sensors by purposely standing in between the doors to garuantee entry into the train as it would affect accuracy of schedules. Every minute makes a difference.
It is always notable that during peak hours, more trains are deployed so at the very least you can wait for the next train. A few minutes won't hurt at all. -
Well, IMO, the TO can't see is people have already boarded or not so they usually go by the schedules (There is a fixed waiting time per train per station based on passenger volumes) and so after that fixed time, doors would close and the train would move on. Sometimes the TO waits for a little extra but sometimes it doesn't.Originally posted by sbst275:Dun say NEL

As far as I know, SMRT Platform Plasma TVs showing the train arrival times are computerized systems. I think they have a sensor throughout the tracks from one station to another, and that signifies the amount of time.Originally posted by ^tamago^:Well, the new WestingHouse doors are slower to open even for SMRT's case (see Changi Airport Stn), but Alstom's trains also does its own checks to ensure the correct alignment thus the delay becomes significant.

For example, if a train crosses the 6 minute sensor, the Plasma TV in the preceeding station would then jump to 6 minutes.
This could be the reason why when new trains are deployed into service, the station cannot track it's position because it is not within reach of the sensor. Only when it crosses the sensor will it change the data. (Sometimes you see the next train timing as 5 minutes but suddenly it jumps to 1 minute. This is the reason that an empty train had just crossed into passenger service tracks and only after crossing the 1 minute sensor the TV reads 1 minute as next train.) -
That's why I suppose there needs to be someone at the platform manning it during the peak hoursOriginally posted by Oceane:Well, IMO, the TO can't see is people have already boarded or not so they usually go by the schedules (There is a fixed waiting time per train per station based on passenger volumes) and so after that fixed time, doors would close and the train would move on.

today i bo chup , people come out half-way i heard the door closing beep i just squeeze my way in , there no way i can be courtesy unless the train would wait

Why people die die must board the train when train doors closing announcement already warning ppl and with LED flashing? Sinkaporeans loves to be kiap everyday???

lol. The above concept is the reason the problem of bus bunching.Originally posted by Oceane:Well, one thing is the train can't stop at a station for too long because it would mess up the accuracy of the schedule.

My point here is that be grateful that the freq of trains are much more regulated than buses. -
They have too much fats.Originally posted by Manager433:Why people die die must board the train when train doors closing announcement already warning ppl and with LED flashing? Sinkaporeans loves to be kiap everyday??? -
Like I've said befOriginally posted by Manager433:Why people die die must board the train when train doors closing announcement already warning ppl and with LED flashing? Sinkaporeans loves to be kiap everyday???
Many of these ppl could have been rejected onboard the prev train -
If I remembered, dwell time at Orchard Stn is 15 sec
By the time ppl alight, it's alrdy 15 sec liao -
Nope... 25 ~ 30 seconds.Originally posted by sbst275:If I remembered, dwell time at Orchard Stn is 15 sec

That's during peak hrsOriginally posted by Oceane:Nope... 25 ~ 30 seconds.
off peak shorter... but still lots of ppl wanna board
Another issue abt Orchard is that the ppl that wanna board tend to be at the front (Northbound)/ rear (Southbound) end -
They want to rush home asap. Who doesn't want to reach home in the shortest possible time? It is understandable after standing for "long hrs" depending on individuals to define it and to them, it can be frustuating.

short dwell 30 secs, long dwell up to 50 secs.Originally posted by sbst275:If I remembered, dwell time at Orchard Stn is 15 sec

tat's only for orchard, most stations dwell 30 secs until the schedule is rush.
u bring a clock with seconds go and observe the schedule of the trains. -
Jurong East Interchange Stn also like that...

You are right. But it does a bit of guesswork.Originally posted by Oceane:As far as I know, SMRT Platform Plasma TVs showing the train arrival times are computerized systems. I think they have a sensor throughout the tracks from one station to another, and that signifies the amount of time.
For example if a train arrived 15 secs late at the previous station. If the train scheduling system updates it schedule to rush to beat that 15 secs, the system will be informed of its ETA at next station and it will change at the exact second of the ETA a minute or two away.
