Lifespan of MRT system.
-
i've got this question for very long liao.
the tracks, overheads and underground, wouldn't they need to be replaced one day?
for those overhead ones, how long can they last?
if there's a need to replace it, how are the MRT gonna do ? -
I have no answers to the first question. But I've been wondering another thing about the MRT. Since it's introduction in 1987, the first trains should be 15 years of age now or at least, soon. Is it gonna be replace or something? 21 new Kawasaki trains were bought recently, but is it to replace the first batch of trains?
Cheers and warm regards -
Well, all the tracks are being maintained and replaced regularly during the off service hours, to ensure that the trains run smooth (or least vibrations) on the tracks. But for the viaduct structures and tunnels, how are they going to be maintained?Originally posted by foga:i've got this question for very long liao.

The very first batch have reached 15 years of age in Nov 2002. But I don't think that they will be replaced soon.Originally posted by Superbus:I have no answers to the first question.

21 EMUs are not enough to replace about 50 older EMUs. Anyway I think the older EMUs will be replaced once they hit 20 or 25 years of age.

I have an uncle who is one of the head engineers of the SMRT. I have an interest in locomotives as well as EMUs (Electric Multiple Units), and DMUs (Diesel Multiple Units), and when I asked about the yellow locomotives in the depots, and how often they go out for maintenance, he told me that they do it every night. I have never gotten a timed exposure of one of these locomotives, but I will one day! Oh, and if you don't know what i'm talking about, re the yellow diesel locos, if and when you pass a depot at AMK, or Tanah Merah, or somewhere, look at the depot, and you will find some yellow locos stabled there.Originally posted by tranquilice:Well, all the tracks are being maintained and replaced regularly during the off service hours, to ensure that the trains run smooth (or least vibrations) on the tracks.

For now, these trains are primarily used to supplement the existing old Kawasaki and Siemens trains during peak hours. You can often see streches of these new trains parked in Bishan depot during non-peak hours, especially on Sundays.Originally posted by Superbus:I have no answers to the first question.

Yes, I've seen this yellow locos many times. Sometimes I see it runs along the tracks as early as 11.45pm. Usually it starts its maintenance works at around midnight. BTW Windy, do you have any info if SMRT is going to buy new EMUs soon? The first batch of EMUs have gone for an exterior refurbishment works recently, and they look quite 'new'. I also remember that SMRT tested bench seats similar to those on buses and plans were under way to implement those type of seating on future trains. Though we all know now that the plans have been scrapped for good.Originally posted by Windy_hates_B10TLs:I have an uncle who is one of the head engineers of the SMRT.

Bench seats? ie. forward facing/reversible seating? I wish they did thatOriginally posted by Superbus:Yes, I've seen this yellow locos many times.

But sorry, mate, I haven't a clue. All I know is that the trains for the NEL will be driverless. -
I don know so much techinical info..but the viaducts, etc. are concrete structures what..should be able to last very long right?
The "Death Railway" built during WW2 is still in use now i believe...so shld be ok what.
Maybe in about 50 years time they totally remake the MRT..flying or something. (Nuts?) -
Hi,
Does anyone knows why there are extra concrete below the MRT viaducts, particularly when the viaducts overpass a road below it, or when there is a track crossing on the viaduct? What is it for actually? Strengthen the viaduct structure?
Cheers and warm regards -
Yes, it is to strengthen the structure. Notice that when the viaducts pass over a big junction, a wide river or has a triple track cross-over, the distance (length) between the 2 rows of pillars are wider, so 2 pillars are used instead of 1 for strengthen purpose.Originally posted by Superbus:Hi,

I remembered asking an SMRT engineer about the strength of the pillars, he jokingly replied that it can still stand should a small plane crash into it. Ridiculous perhaps, but it says much about the strength of them.

Wel last time i went to stay in my cousin house in Northvale in cck beside the mrt at the hoildays.At midnight(wed),there will be a yellow colour one carrige train(loco) that comes here and there.It is the maintaince train.And sometimes there is a Four-carrige 1st generation mrt train that comes ramdomly.It is the train where smrt collects the money from that station(cck) earned from ticketing machines.Originally posted by tranquilice:Well, all the tracks are being maintained and replaced regularly during the off service hours, to ensure that the trains run smooth (or least vibrations) on the tracks.
