I think many of the well known train manufacturers are now moving to China to do the heavy and labour intensive work. It inevitable for cost consideration.

Singaporeans have learnt to tell their bosses good news. Even if it not their fault but the supplier's fault, they will help cover it up and sometimes it becomes a hole they keep digging as in this case.

The local press has also become the "official certifying authority on all facts" that readers lap it up. Poor critical thinking has made this a vicious cycle.

Steel/Alloy production is like baking. Ask any pastry chef and he will tell you how easy it is for things to go wrong. Cooking can be done "to taste". Baking requires precise measurements and temperatures.

Get anything wrong and a whole batch is ruined. That is why the integrity of the manufacturers in paramount

The decision to write off millions of dollars of product is a painful but necessary decision which requires putting quality and reputation above immediate profit.

I doubt if any Tiong company reached that level yet. Even leading American companies were making "business" decisions regarding quality a little more than a decade or so ago.

I think you misunderstood that there is only one type of bolster, installed between the bogies and the car body and it is not made of aluminum alloy. I think that is not the case. There are 2 types of bolsters. One is attached to the bogie via suspension and it can rotate. This type of bolsters are not made of aluminium alloy. There is another set of bolsters welded to the car body. These bolsters are made of aluminium alloy. They are aluminium beam welded across the bottom of the body to reinforce the car body and help to transfer the weight of the body to the bogie. They are called car body bolsters. Not the same as the bolsters of the bogies. The car body bolster sits on the bolsters of the bogie and have attachments for coupling them together.

The official statement said that cracks are found on the car body bolsters (not the bolster of the bogies) so my comments were based on their statement. Anyway, I think the bolsters of the bogies are made of steel and it is unthinkable to find cracks in steel which was invented to replace iron to overcome the brittle nature of iron.

Below is an extract from LTA'so statement :

"We did not send all of the trains back at once as they were still fit and safe for service and we wanted to ensure sufficient train-availability for commuters."

I felt that it takes a very experienced PE with vast exposure to conclude that the car bodies are still fit. He or she must have good knowledge of how aluminium alloy stress crack propagates and felt that it is still safe.

As to why the need to send back the car body with bogies, i believe that it is easier to return the whole thing rather than dismantling it. If I am not wrong, they also deliver the body with the bogies assembled together. Otherwise, they will need to assemble the bodies to the bogies.

Looks like you bought Govt story hook, line and sinker.

There were cracks on the bolster which is made of steel and not aluminium. There were cracks on car body made of aluminium. There are cracks and defects on the bogies itself. All 3 components can be separated easily at any service dept. These are modular in nature.

Yet the entire train is being returned. New car bodies will be fitted and all the bogies and bolsters will be replaced.

Govt well known for what is stated and what has been omitted. Common sense will tell you if its only the bolster, they should have been fitted in a matter of days. It only 2 per car and modular construction. New ones can be sent to Singapore.

Why change the entire car body. Why even sent the heavy bogies back? You got to learn to ask question to clear your own doubt.

If its hairline crack only, why need 4 months to fix? They can build an entire brand new carriage in 4 months. Must be more serious then that. Also ST Aerospace is specialist in refurbishment of aircraft including testing and fixing of structural metal fatigue problems in planes, which after all are made of ..................ALUMINUM ALLOY!! So, if it cannot be fixed in singapore, its way more serious then they say. Lying pieces of dogshits.

Actually they want to fit toilets in the cars to enhance commuter's travelling experience.

I do agree. It just means that if you Chinese, the scrutiny has to be many fold. And it is something many know what to do when it comes to Chinese products. Obviously our Govt has not idea despite getting royally screwed in Suzhou

Thats exactly wha they are doing - practically building a new train.

How could they admit? when the founding father's fathers were honoured at their ancestral village...it is like telling you, "we are one family" , what is taking a few billions ?..." ji get yang".....psst!..quietly it is translated as " dieu ai see futt"..

I read the LTA statement again. They have actually stated that the entire car body will be replaced. Below is extracted from lta's statement :

Due to the nature of the defect, the most effective way of addressing it is to replace the entire car-body shell. As the trains were under warranty, we required the contractor to replace the entire car body shell. Hence, since July 2014, the affected trains have been progressively sent back to the factory for rectification works. The costs of the shipping are borne by the contractor.

the aluminum plates and alloy parts needed to be reproduced from scratch and replaced as there are some flaws in their manufacture. the transfer of energy is dynamic and the cracks can occur anywhere and all over. so instead of piecemeal and modular replacements it's better to send the whole damned car back and have all aluminum parts and panels replaced. you're wasting your breath trying to convince a fool who believes in his own hubris - such as a narcissistic nerd who tries to teach a pimp how to fuck his prostitutes. someone half-baked in train technicalities and armed with half-baked theories is more dangerous and destructive than a complete moron. the tpx is no longer interested in science and rca but stoking the fires with wild conspiracy theories.

I think you are missing the point and the big picture. They cannot adequately let alone convincingly explain why the whole train has to go back. No one will accept that thus far LTA have provided sufficient clarity and the matter can now be closed.

I think the LTA guy who drafted the statement is a technical chap and took too many details for granted that the public will understand and did not elaborate on why the whole train has to be sent back. The PR person must also have been overdosed on the technicalities and overlook the concern that the general public will raise.

It is fair for a layman to question why ship back a whole train if the defect is confined to just the aluminum alloy of the body and sub-floor. However, if we consider the amount of electronic components, wiring, sensors ... that are installed or hidden in the car body, it is not possible to replace the car body at site. In fact, some of these parts may have to be installed when the body is partially built so that there is easy access. I think they are actually rebuilding new cars and re-using whatever electronic parts from old cars that can be savaged.

Then there is the issue of alignment. If the assembly job is not properly done in a designed factory with proper working space, facilities, tools and equipment, there will be loose connection and misalignment resulting in vibration which will be translated to noise and more future failure.

Perhaps LTA should have provided a better picture of the actual auxiliary work involved for changing a car body shell especially when the issue was brought to light by others which raises suspicions and speculations.

i showed the post where it says the car body parts and bolster assemblies can be easily replaced and or repaired in the depot to bart engineers and we looked at one another and laughed so hard. laymen and wannabe experts do not know that many parts and panels especially at the sub floor are welded. thank you guys for the entertainment.
