When Singapore left Malaysia in 1965, there was no border control between the two countries. When the two countries established border controls, both the Malaysian and Singaporean Customs, Immigration and Quarantine (CIQ) officers were stationed at Tanjong Pagar for clearance of railway passengers. Road travellers clear immigration at the Malaysian side of the causeway and Woodlands, Singapore upon entry to Singapore. In this case, the CIQ of both countries are separated.
