national disgrace!!!!!!

 

you dun see the same thing happen to HK or thai land!

I dont think welding is allowed as this claw is attached to the third rail. The third rail is not 100% straight, it varies due to rail structure or expansion n contraction of rail(rain n hot sun).

 

So u must allow for some elasticity in the claw.

 

They should instead design a bracket clamp to secure the claw. We have WITS in SAF, SMRT should learn from SAF. It is the ppl who work on the job knows what improvement is required. Rather than some expert from nowhere.

 

Remember US invented the pen that can write in zero-gravity??? The russian just use a pencil in space.

 

True, the best and most appropriate improvements should come from people on the job itself.

 

But i've got a nagging suspicion that the maintenance department has already been sidelined by SMRT's management eons ago. Thus, whatever issues and ideas being raised by them had already brushed aside in the name of higher costs. -_-

The invention of aircon has been perceived as the greatest of all time, helping tropic countries work within comfortable environment and achieved greater productivity. Especially for Singapore.

Cable ties should be a close 2nd. From propping up highly stressed structures to identifying ownership of utensils. The humble plastic had contributed greatly to our nation's progress.

The one who suggested to use cable ties for holding the claws probably had been commended for helping the company saved lots of money [laugh]

best invention not duct tape meh??

Cable ties failed to stop rail claws from dislodging

 

SINGAPORE - An SMRT line manager revealed that rail claws on SMRT's rail network continued to dislodge even after they were secured with cable ties.

 

Night duty officer Mr Loke Kwok Hoong was working after the train disruption on Dec 17.

 

He revealed to the Committee of Inquiry (COI) that cable ties were placed around all claws on the North-South and East-West lines during a thorough joint inspection by the Land Transport Authority and SMRT.

 

 

When asked why the claws could have dislodged, Mr Loke said the cable ties used were "normal", and not "special ones".

 

COI member engineering professor Lim Mong King asked Mr Loke if he knew of other times when claws have dislodged even with the cable ties in place, to whcih Mr Loke replied in the affirmative.

 

Mr Loke was also questioned about a cracked mirror of a multi-function vehicle used to inspect the third rail prior to 17 December.

 

Loke said he did not know about the cracked mirror till after the 17 December disruption, and added that if he were on duty on Dec 16, he would have been concerned and asked for inspections to be done.

 

But he clarified that not all night duty officers have the same knowledge about the inspection vehicle.

 

The hearing continues.

 

Now who are they trying to kid?

 

Its obvious that the cable ties idea is given and implemented by idiots at the first place. And is there something such as "special" cable ties?

 

SMRT is a bloody joke to think that such a "quick-fix" solution combined with reduced speeds are adequate enough as stop-gap measures. <_<

I believe special cable ties = apron string [laugh] Perhaps evidence they called themselves Singapore Mentally Retarded Trainees

Any news on mrt fare discount? Since the justification on fare hike is improving service quality.. Now no service delivery, more time wastage, 20 min journey become 30minutes journey bla bla.. So can commuters be charged the old fare before the hike?.

i remember studying something like moduless elasticity,i think the metal claws being non elastic if not allowed to vibrate and being welded down may result in breaking.

You got the point. You are right. However, SMRT got many Professionals said nothing at all?

Maybe now the inspectors have to use more cable ties to fasten the existing cable ties and prevent them from loosening? [laugh]

Trial and errors expertise from mentally retarded to suggest using cable ties at all :o

Why didn't SMRT use superglue and rubber bands in addition to cable ties as well?

 

The above are also cheap and fast solutions which I am sure the SMRT management will approve in a hearbeat.

 

 

[laugh][laugh]

Thats more advanced? [laugh]

Yeah, and please use some of karung guni's raffia string for added rigidity as well. :D

 

So much for "Tried & Tested", "Recommended by OEM" and "International Experts"...

I believe we are paying for such expertise from such experts [sweatdrop][shakehead][thumbsdown] Every morning they announced: this train will be slightly delayed due to congestion arriving and departing the platform. We apologise for the delay to your journey (meaning we can live beyond age 100?) [laugh][thumbsup]

Saw saw it coming. And she sees to it that she is out of judgement calls when the shiits start spilling out.

Very Heng.

Allow me to offer my say. i think being a critical support structure which lends mechanical strength, you wouldn't want elasticity to be a big feature of the material used. I wouldn't want to use Young Modulus as a critical parameter to evaluate possible materials.

 

In our context, cyclical stress is highly pronounced and metal fatigue will be highly exacerbated. You need forged rather than cast metals in this instance. Like Shull, i am in favour of welding. Specifically line welding over spot welding. In the absence of credible calculations, i am actually still doubtful whether welding in itself is sufficient to withstand for a turnover period of say realistically 10 years.

Good engineering practice does not allow either of these methods. But got many engineering professionals employed by SMRT for malingering?

Those $1 pack c/w 3 stick elephant super glue. Cheap and effective. [laugh]

Mercy-mercy. They may not be able to apply such advanced techniques (perhaps glued themselves there insteasd) [laugh]
