The BIG Breakdown or Meltdown

Its all in the numbers my dear, which is why I love crunching them.Hmmmm... 3boys. Good point. Assuming that the numbers are correct. Good point. I'm half convinced. Need to think.
Still doesn't resolve problem of maintenance...
I see a big fine for SMRT coming up from the regulators (LTA), which is deserved. They will need to invest more into maintenance, or face punitive action (or we will demand it). -
i am not a engineer...so how long can this plastic cable work?
[quote]Even as they deemed the initial assessment of last week's major service disruptions reasonable and fair, transport experts yesterday questioned SMRT's use of plastic cable ties for short-term repair.
Those my paper spoke to felt that the transport operator should justify this move. The cable ties, along with steel support brackets, were used to secure the \"claws\", or metal grips, which had become dislodged.
An overnight joint investigation by SMRT and the Land Transport Authority (LTA) last Saturday revealed 21 missing claws along the North-South and East-West lines. These secure the \"third rail\", which supplies electricity to trains.
Associate Professor Lee Der Horng, a transport researcher with the National University of Singapore, said he believes SMRT will be looking for other ways to provide \"even a temporary solution\", because if further vibrations occur, the plastic cable ties would not be able to take it.
Transport analyst Tham Chen Munn, who is the director of Transport and Urban Design Consultancy Services, said: \"Can any mechanical system that is subject to extreme loads and frequencies be secured with plastic cable ties?\"
As a result of the dislodged claws, the third rail had gone out of alignment, preventing the collector shoes on the trains from getting power, according to preliminary investigations.
LTA officials also said on Sunday that the claws might have fallen off due to vibrations in some sections of the tunnel tracks.
Still, Dr Park Byung Joon, programme head of the Master of Science in Urban Transport Management at SIM University, said that other measures which have since been taken are a step in the right direction.
This includes imposing a speed limit on trains running through the city area, where most of the missing claws were found.
\"Slowing the trains down is the only way to make sure impact (on the third rail) is minimal... For the time being, it's the right way to reduce vibration,\" he said.
However, experts agreed that other factors, including an increase in passenger load, should not be ruled out for causing the disruptions.
Prof Lee said: \"More passengers means the train becomes heavier... At this stage, we cannot exclude (other) possibilities.\"
Mr Tham said: \"An overload on any system, coupled with other factors such as wear and tear, can cause a chain of events.\"
Meanwhile, SMRT saw its shares fall as much as 3.6 per cent yesterday, to its lowest level in more than two months, reported Reuters.

Find it scary as on sunday, I was taking train from Ang Mo Kio to Yio Chu Kang to collect books from Waywei (one of the kiasuparents), the train just cannot stop at Yio Chu Kang. It overshot Yio Chu Kang by about one carriage, I felt like hanging midair, as I'm at the front end. If the door had opened and one is daydreaming, one would have walked in the air. :scared: In the end, I had to get out from Khatib and took the opposite train back to Yio Chu Kang.
My opinion is something wrong with the brake as the train can't stop exactly on the right place. Really really scary! In the end, I take bus back home instead. -
My question is how long has this problem been there? Did SMRT do any maintenance on the tracks and train? How many times they do it in a year?

A big fine is no going to do any good as the co can in the near future submit a proposal to increase fare to transport council by citing increase operating costs. Invariably, co can recover whatever fine that is imposed upon them. A better strategy will be for the co's board to withold the coming bonuses of top management till the findings are out.
Remember is the neligence caused by people running the operations. -
I’m not blaming or pinpointing anyone. I just hope that the problem can be resolved quickly. Many lives will be involved if an accident really occurred from it. It’s not a laughing matter! Even $$ cannot make a dead person alive!

Depends on the amount of vibrations & friction.i am not a engineer...so how long can this plastic cable work?
I don't think the plastic cable ties can hold for long.
As they are so-named, they are usually for bundling cables together.
Not really for these mechanical parts...
Dunno why they dare to show this to general public. -

we were told they are supposed to be doing it on nightly check -

what kind of news reporting .........
and SMRT has not shown any concern yet
