Punggol LRT line
The Punggol LRT line is an automated guideway transit line in Singapore. The line, which initially opened on 29 January 2005, connects the residential districts and suburbs of Punggol to Punggol Town Centre, where it connects with the North East MRT line and the Punggol Bus Interchange. It is the third line of the LRT system in Singapore and like all other LRT lines, it is fully elevated and uses automated trains.
The first phase is a line with 15 stations in two loops. It is the second LRT line to be operated by SBS Transit.
History
Plans for the Punggol LRT line were drawn up and announced in January 1999 with the development of Punggol New Town. Construction began in June 2000 by a consortium comprising Sembcorp Industries, Mitsubishi Heavy Industries and Mitsubishi Corporation, at a cost of S$354 million. Meanwhile, the Punggol LRT line was awarded to Singapore Bus Service on 20 May 1999. 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 that year, which conducted more trial runs and staff training before the opening of the East Loop on 29 January 2005. However, due to limited developments around some stations on the loop at the time, only the stretch of stations from Cove station to Kadaloor station were opened. The West Loop opened in stages on 29 June 2014.A covered middle platform at Punggol and a short track piece branching from Teck Lee had already been built in anticipation of a possible Punggol North LRT line, but these plans were subsequently scrapped, and a new Punggol Coast MRT station is being built instead.

Improvements
On 31 October 2012, the Land Transport Authority announced that by 2016 the Sengkang and Punggol LRT lines would be upgraded to two-car trains, doubling the passenger capacity. An additional 16 more cars were to be ordered, bringing the total fleet size to 57. The longer trains also required modifications to the signaling and communication system.On 29 December 2016, trains started operating in the two-car formations on the line's East loop during morning and evening peak hours from 6.45 am to 8.45 am and from 6.15 pm to 8.15 pm.
