"SMRT train collision due to 'inadvertent' removal of software protection feature
SINGAPORE: The “inadvertent” disabling of a software protection feature has been identified by the authorities as the reason for an SMRT train hitting another, stalled train at Joo Koon station on Wednesday morning (Nov 15).
Twenty-eight people were injured after a train “moved forward unexpectedly” and “came into contact” with another stationary one in front of it, according to earlier statements from the Land Transport Authority (LTA) and SMRT.
At a joint press conference held later Wednesday, LTA deputy chief executive of infrastructure and development Chua Chong Kheng said preliminary findings indicated that the first train - in front - departed Ulu Pandan with a software protection feature which was “inadvertently removed” when it passed a faulty signaling circuit.
“This train then arrived at Joo Koon station without the feature,” said Mr Chua. “This resulted in it giving off a train profile on the new signaling system of a three-car train instead of a six-car train.”
“As a result, the second train (behind) detected the first train as a three-car train and misjudged the distance between the two, causing a collision.”
Mr Chua said that as a precaution, operations from Joo Koon to Tuas Link will be suspended for the entire day on Nov 16 while assurance checks are conducted with signaling contractor Thales."
Looks like somebody has to suffer physical harm before the series of mishaps really get the authority to be very serius!!
Hope that the injured passengers, especially the 2 categorised as "emergency cases" recover well.
In the meantime, let's hope this "inadvertent removal" of train safety protection software after "passing a faulty signalling circuit" is not random!! Otherwise it will b a very stressful trip everytime someone gets on the train!!
Maybe it is time to shut down the lines n do a total check!! Let SMRT lose money as it is private n using our own taxpayer's money anyway!!
Siah...
