SMRT will be required to carry out more stringent checks and replace the running rails earlier where necessary, the Land Transport Authority said in a statement today.
LTA said it is concerned and is investigating the root causes of rail cracks after the latest incident occurred on the North-South Line earlier this week.
LTA added that it is too early at this stage to determine if there is any underlying link or systemic issues that contributed to these four recent rail cracks.
LTA also said SMRT, which operates the North-South/East-West Line, has a system of running rail replacement similar to the approach adopted by operators in other cities - whereby individual running rail segments are replaced when there are defects, or when the wear and tear for that rail segment warrants it.
To better determine what further measures can be taken to address the situation, LTA will be appointing an international trackwork specialist to assess the condition of the rail and to advise on possible changes to the operator’s running rail maintenance regime.
