Concourse level of Punggol MRT/LRT station, with escalators leading up to the LRT platform.

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 10.3-kilometre (6.4 mi) 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. 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, which 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.

A covered middle platform at Punggol and a short track piece branching from Teck Lee have already been built. These are meant for Punggol North LRT of which it was subsequently scrapped and replaced by Punggol Coast MRT station.

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 signalling and communication system.[9]

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 6.45am to 8.45am and from 6.15pm to 8.15pm. Service frequency will be maintained at three to four minutes during morning and evening peak hours.[10]

On 15 December 2017, the Land Transport Authority said there will be limited services on parts of the Sengkang-Punggol LRT (SPLRT) on most Sundays from 14 January 2018 to 25 February 2018, to facilitate renewal and improvement works from (except 18 February as it is a Chinese New Year holiday). Only one platform will open for service at 5.30am on Sundays. The other platform will open from 7am.[11][12][13]On 22 February 2018, SBS Transit said the arrangement is expected to continue until end April 2018.[14][15]

From 27 May 2018 to 7 October 2018, limited services on Sundays will continue on the Sengkang-Punggol LRT (SPLRT). One platform will open at 5.30am and the other platform will open at 5.30pm.[16][17]

Rolling stock

Trains operating on the line are Mitsubishi Heavy Industries Crystal Movers C810s and C810As. Trains operate from the Sengkang Depot which provides maintenance and train overhaul facilities for both the Punggol and Sengkang LRT lines.

Train formation

The original system consists of single-car C810s. Each unit is 11,200 millimetres (11.2 m) long and can carry up to 105 passengers. 16 original C810s were modified to allow two-car train operation and 16 C810As came with this configuration. This boosted capacity to 204 per trip.

Train control

The line is equipped with Kyosan APM fixed block signalling system for Automatic train control (ATC) under Automatic train operation (ATO) GoA 4 (UTO).[18] The subsystems consist of Automatic train protection (ATP) to govern train speed, Automatic Train Supervision (ATS) to track and schedule trains, and a computer-based interlocking (CBI) system that prevents incorrect signal and track points settings.
