Chitchat Only a software glitch - train collision

[halsey02]

More nonsense to confuse the public. Let's get the fact clear :

1. From Pasir Ris to Ponieer it is under old system - fixed block, so train behind cannot move if the 'fixed block' in from is occupied.

2. From Pioneer to Tua, it is under their so-called bubble system, ie moving block

For moving block system, the key safety feature is that when any one train loses its "protective bubble", the system will stop all trains under automatic mode. That was what happened to the circle line the last time. The system kept receiving conflicting signals.

So we can override the system to go on restricted manual mode as reported. Isn't it a clear breach of safety rule to allow a faulty train to operate on manual mode without a protective bubble and at the same time allowing the trains behind to continue on automatic mode; knowing that the system cannot "sense" the faulty train. They have also not explained why the 2nd train knew how to stop 36m away if there was no bubble in front before moving off again 1 minute later.

I can comprehend what you are saying & many others, reading do too, but, those BLOCK heads will still vote in the immovable BLOCKS, who will hide under many layers of their explanations to come out roses.

We have a mismatched system of old & new...the argument will come in again that, we have to pay for better softwares, better hardwares, better people who can make the system work...by raising fares, taxes & so forth.

So, you can explain the BLOCK whatever till the cow comes home.....in which is an interesting read & learn....but those BLOCK heads of the 70%...don't learn, even they can read...

It is easy to blame software or hardware but easier to not blame the actual management of it.

my uncle say pm lee is a laughing stock for wanting to have first land to have driverless car when he cannot even manage a few driverless train.
