The Public Transport Security Command (TransCom) Chinese: 公共交通保安指揮處) is a specialised transit police unit of the Singapore Police Force. It was first established as a unit of the Special Operations Command under the name Police MRT Unit in 2005 in response to the need for greater security concerns in public transport operations in Singapore as a result of global security issues. From 15 August 2009, the unit was upgraded into an independent unit and took its present name.
