COMPLAIN TO LTA! I want see what will SMRT do... probably nth...
hmm i am thinking if LTA upgrade our current NSL and EWL to fully automated driveless system, is it possible as least more constant... least of any oh how bake

Haha...it happens now & then....what can we do??

I encounter this mrt driver, stop, start, then stop and start again. quite irritating sia.
I would appreciate if the driver stop suddenly and park there for 1 min or so, pls announce it to the passengers on what is going on. some people might be in a hurry for work, appointments.
Erm... they only stop if there is a train in front.... or you rather they slam into each other?
i think theres train at the next station.this always happen in the morning where the train comes only in 2 min interval.quite iritating.like this isnt it the same.expect u are waiting in the tunnel rather than waiting at the station

feel sorry abt ur bad experience on the train man. well, i suppose ur not so familiar with how the system works i believe. Unlike buses where drivers can gradually stop the veheicle when seeing another veheicle infront, a train is normally running on Auto mode in layman terms auto pilot during dry weather or normal condition. in other words, the job of the driver is only to open n close the doors and press a button for the computer to take over and start moving the train out of the station. Braking and acceleration are all carried out by the on board computer of the train.
the sudden braking u experinced is mainly due to the ATP (Automatic Train Protection) system that kicks in when the train ur in is too close to the train infront which is around 1.5 - 2 min interval time. When the ATP system kicks in, force of braking might be rather high is order to stop the train asap to prevent any collision from happening. i hope im correct, the lao jiaos here correct me if im wrong.
so dun blame the driver la, blame the system haha. maybe we might need to change the system for a smoother braking maybe coupled with a increase in fare for overhauling the system?　haha Im sure u wont want so just suck thumb n endure loh.
in the future, will all the trains be driverless?
yes if our population continues to grow it will come to a point where NSL n EWL will require to overhaul their signalling system to improve the frequency of the train arrival. As such maybe they will consider incoperating the driverless system in. well just my 2cents tots...

no lar im not an enginner or worked at mrt before. just that i have special interest in auto-mobile n transport stuff so have a little bit of knowledge on these things. aniwae hope my explanation allows u to understand the system better. cheers.
yea do agree with E5's view. i over-looked the point on raining conditions that may cause over/under-run. But i think it still can be done. just look at both of our LRT systems which operates above ground . Mayb the sensors n systems may differ for MRT n LRT but im sure smth lyk tht could be work out in the near future. Nevertheless, i still feel more secure to travel on a train with a driver on board..still remember years back when a car went onto the tracks over at lentor ave when a train was approaching? wonder wad would happen if it was a driverless train. *shivers*
and if im nt wrong theres the traction control system on the train when there is a possiblity of a wheel spin or lost of traction isit? always hear the peumatic sound when the train suddenly comes to a halt when it enters heavy downpour or when it is stoping during wet weather condition. E5 dun mind if u could shed some light on that?
wow very comprehensive explanation. bro r u an engineer or smth?

zhlow, so TO's job is just maintain the train when it come to ATP mode? Control of the doors too? Is it difficult to control the train? Is like, when you pull down the brake, will the train slow down like those normal vehicle or it takes time to slow down? I play before those train stimulator game, when i want to slow down or stop the train, it take quite sometime to fully stop, is it same as those normal MRT?
Originally posted by E5:It largely depend on what train you drive as all of them has different characteristic when accelerating and braking. The following is the difficulty of driving C751B, C651 and C151 from easy to hard;
C751B -> C651 -> C151
What train simulation game do you play anyway?

here's the link that i've play this train simulation, is difficult to brake when it come to a station, not like those vehicle, when you depress the brake harder, it will stop in a lesser timing, but for train, will it be like those car?
Originally posted by E5:Yeah, it work the same as the car.
sure it work as the same as the car? when it depress the brake, the train will also start to slowly slow down like the car too? Not like the train simulation game? Did you try playing?
