SINGAPORE - SMRT is working with the authorities to address vulnerabilities that are unique to its Bishan depot due to its location and design, the public transport operator said in a statement today.
The depot has seen three security breaches since 2011, with two of them taking place six months apart this year.
SMRT said that the recent breaches point to vulnerabilities that must be addressed, adding that it is determined to ensure the adequacy of security measures at the depot.
It said: "The original open design of the Bishan depot poses a number of unique challenges because of its size and full visibility from adjacent buildings.
"It has a fencing perimeter of 6.5km, and this has been reinforced with enhanced security features following the breach by vandals in 2011. These fences were not found to have been breached in the two recent cases in 2014.
"Further security measures were, however, put in place within the depot perimeter following the incident in May this year.
"We have noted that the 30-hectare Bishan depot, built on a concrete platform deck over swampy land which is the flood plain for the Kallang River, has a network of canals and drains running underneath. This presents vulnerabilities that are unique to the Bishan depot."
SMRT said it has been collaborating with the authorities to urgently address the identified points of vulnerability to further safeguard the depot and its transport assets, while keeping in mind the pertinent drainage considerations.
The public transport operator has pledged to develop "an effective strategy that encompasses deterrence, vigilance and swift response against the prevailing threats" with assistance from national security agencies.
