Defective and damaged cables along the Circle Line will be replaced by the Land Transport Authority (LTA).
The Straits Times reported today that the faults in the cables were found to be due to poor workmanship and manufacturing defects.
As such, Alstom, the contractor in charge of laying the cables, will bear the replacement cost. It did not disclose how much the cost is.
The damaged cables were discovered after a breakdown in September last year that affected about 27,000 commuters.
A damaged direct current cable at Dakota station had caused the power trip, taking down the whole line.
Subsequent investigation showed that some batches of Circle Line cables showed manufacturing defects such as gaps in the cable insulation. Some were damaged during installation and were shown to have scratches on the external sheath, said the paper.
LTA said train service will not be affected by the replacement of the cables. It will be working with Alstom to do a site survey as well as assess how much needs to be replaced.
New checking processes have been implemented in a programme likely to start next year and end by December 2015.
As a result of LTA's finding, train operator SMRT will not be penalised for the four-hour breakdown as it was found to be not at fault, reported the paper.
Despite this, it will now increase the frequency of its checks - from six-month intervals, cables will now be checked every three months, reported the ST.
LTA said procedures to identify faults have been improved in order for SMRT to resume services more quickly.
