Punggol LRT station, the centerpiece of the line, is located directly above the Punggol MRT station, thus linking up the Punggol LRT Line to the Mass Rapid Transit system that spans the entire island of Singapore.
Construction began in June 2000 by a consortium comprising SembCorp Industries, Mitsubishi Heavy Industries and Mitsubishi Corporation, at a cost of S$354 million. Construction of the first phase was completed in June 2004, and underwent testing by the Land Transport Authority. The system was handed over to SBS Transit on 1 December 2004, who conducted more trial runs and staff training before the opening of the East Loop on 29 January 2005. The West Loop opened on 29 June 2014.

On 31 October 2012, LTA announced that by 2016, Sengkang and Punggol LRT systems will be upgraded to a two-car system for 16 of the 41 existing train cars, allowing double the number of passengers to board at any one time. Each train car can take up to 105 passengers. Hence, there is also the need to modify the signalling and communication system.
