million. Originally projected to open in 2012, then Minister for Transport, Mr Raymond Lim, announced on 12 February 2009 that the date was pushed forward by a year, to 2011. Construction started in 2009 and was completed and handed over to the operator at around the first quarter of 2011, with the new platforms and track being tested since then, before the announcement on 16 May 2011 about its operation date on 27 May 2011. To connect the new train tracks to the existing tracks, train services between Joo Koon and Clementi were halted on 4 & 5 September 2010 (affected substation is Chinese Garden, Clementi and possibly Dover), followed by train services between Jurong East and Bukit Gombak on 18 & 19 September 2010 (affected substation is Bukit Gombak). Initially, the new platforms and track were only operated on weekdays except public holidays, during the morning peak hour period from 7:00 am to 9:00 am. Evening peak hour operation from 5:00 pm to 8:00 pm on weekdays started from 27 December 2011 while the morning peak hour period was extended by an hour later to 10:00 am after the next batch of new trains became ready for revenue service. It was then extended progressively to between 6:00am and 11:00am, and after 5:00pm till 9:00pm. To make full use of the new platforms, terminating NSL trains heading to Ulu Pandan Depot also use Platform A to minimize interference to through services as well as for the last train to Kranji, overnight parking of the trains were being done at Jurong East Platform A from 1:15am to 5:00am daily; the other location that was being done is at Tuas Link Platform A to minimise dispatches from depots at the start of service. The station was retrofitted with half-height platform screen doors in 2009 which commenced operations on 18 December 2009. High-volume low-speed fans were installed at the station between 2012 and 2013. Noise barriers and privacy screens were installed between January 2011 and September 2014 to reduce the amount of noise generated towards residential areas. The former spans from PIE to Block 266 Toh Guan Road, and from Block 266 Toh Guan Road to Boon Lay Way and Block 108 Jurong East Street 13 to Jurong Town Hall Road in the latter.
