East–West Line (EWL) The station was constructed as the terminus of an extension of the
East–West Line from
Tanah Merah station, which in turn was part of Phase 2A of the MRT system. The contract for the construction of the stations from Changi Depot to Pasir Ris and of tracks was awarded to Sato Kogyo Pte Ltd at a contract sum of S$91.89 million (US$ million) in March 1986. The contract also included the construction of the
Tampines and
Simei stations. The station opened on 16 December 1989 as the eastern terminus of the EWL as announced by then-deputy prime minister
Goh Chok Tong on 4 November that year. The opening ceremony, officiated by then-Minister of State
Mah Bow Tan, included an MRT ride for Mah and four other
Members of Parliament from Simei to this station. The installation began at Pasir Ris station in August 2009 and the doors began operations later in November.
High-volume low-speed fans were installed above the platforms of the station between 2012 and 2013 as part of a national programme to improve ventaliation at station platforms. On 29 June 2018, the
Land Transport Authority (LTA) announced that the EWL overrun viaducts would be extended by . A new crossover, in conjunction with the implementation of
communications-based train control (CBTC), will allow faster turnarounds for trains and segregation of platforms at the terminus. The station's operations will be unaffected by the works as the enhancement works will be done away from the station itself. In March 2019, the contract for the construction of new overrun and crossover tracks was awarded to China Civil Engineering Construction Corporation Branch Office Singapore / Gates PCM Construction Ltd (JV). The S$56.7 million (US$ million) contract included the partial removal of existing overrun tracks. Construction commenced in 2019 and was completed in May 2024. , only off-service trains uses the
turnback tracks.
Cross Island Line On 17 January 2013, transport minister
Lui Tuck Yew announced that the proposed
Cross Island Line (CRL) will serve the Pasir Ris area. On 25 January 2019, the LTA confirmed that Pasir Ris station will be an interchange with the CRL. The CRL station will be constructed as part of Phase 1, consisting of 12 stations between
Aviation Park and
Bright Hill, and was expected to be completed in 2029. On 10 March 2020, it was announced that this station will serve as the eastern terminus for the CRL extension to Punggol station. The Punggol extension, consisting of four stations between this station and Punggol, was expected to be completed in 2031. However, the restrictions imposed on construction works due to the
COVID-19 pandemic has led to delays and the dates was pushed by one year to 2030 and 2032 for CRL1 and CRLe respectively. The contract for the design and construction of Pasir Ris CRL Station and associated tunnels was awarded to a joint venture between Daewoo Engineering & Construction Co Ltd and Dongah Geological Engineering Co Ltd Singapore Branch at S$980 million (US$ million) on 26 April 2021. Construction was scheduled to begin in the fourth quarter of 2021, with expected completion in 2030. When completed, the CRL station will be the second deepest MRT station on the network at underground, behind
King Albert Park's CRL station at . On 8 October 2023, a part of Pasir Ris Drive 1 between Pasir Ris Drive 8 and Pasir Ris Central was closed off to facilitate the construction of the station.
2016 rail incident On 22 March 2016, two SMRT maintenance trainees were run over and killed by an oncoming
C151 train at around 11:10am. They were part of a team of 15 personnel tasked to investigate a possible signaling system fault, after a high voltage alarm set off. The incident took place at the track switch away from the station. This led to a 2.5-hour train service disruption from 11:10 am to 1:56 pm for train services between Pasir Ris and
Tanah Merah, and had affected at least 10,000 commuters. After an internal investigation, SMRT sacked both the engineer who led the track team and the train driver and also disciplined the staff involved for their role in the incident. The sacking of both employees attracted online controversy, with Singaporeans on social media questioning whether it was fair to sack the train driver.
SMRT Trains, the director of control operations and the SMRT engineer who led the track team were charged for the incident. Upon investigation, it was revealed that safety protocols were not implemented that would have prevented the train from entering the worksite. The engineer who led the inspection team was charged with
negligence causing death under the
Penal Code and was subsequently sentenced to 4 weeks in jail. SMRT Trains and one member of SMRT management were charged for violating the
Workplace Safety and Health Act for lapses which led to the accident, and $55,000. On 20 July 2018, the Land Transport Authority fined the operator S$1.9 million (US$ million) for this incident and the
Bishan tunnel flooding. ==Details==
