I wonder whether there is a serious design flaw of the controlling system. We cannot expect the signaling system working perfectly at all time and it will break down at some point some time. It is inevitable.

A false-safe mechanism must be in place even if the train is operated manually. The control board should be able to monitor the exact position of every train at any time. A device on board must be able to give warning to the drivers of two trains when they get too closed to each other even when the  power on train is down (like what is equipped on an aircraft)     

I just cannot understand how can an accident like this could happen under the technologies we have today.

Bun 7 Lik.  Learn how to read human words first before barking.

What I said is the controlling system and signalling system is just part of the bigger system controlling the operation of the train network.

Your computer science degree did not give you the ability to understand this?

What a bun 7.

as rocky said..the main control centre should be able to tell if the 2 trains are too closed coz the ...

That is something does not sound right to me.

最終底線: 無論控制中心指令, 無論司機人手操控, 列車本身都應有獨立最終的防撞系統, 絕對防止撞車, 絕對要求列車保留安全距離.

This technology and equipment are available.  It is an independent system to ensure the safety regardless the command from the control center (of course, it can still be overrided manually or ignored the warning).   That is the reason I cannot understand how it could happen.
