A West Coast extension to Haw Par Villa station, which is a part of the Circle Line, is under consideration.

[5] An LRT line for the Jurong area was first announced in November 1998 as part of feasibility studies by the Land Transport Authority (LTA),[6] though communications minister Mah Bow Tan said the sustainability of such a project would depend on demand and ridership.

[7] The Jurong Region Line (JRL) was formally announced on 23 October 2001 by transport minister Yeo Cheow Tong.

The light rail line was planned to serve the residents of Jurong living in areas beyond the EWL alongside students from NTU.

[8][9][10] However, in May 2008, the project was put on hold due to the lack of financial viability based on passenger demands of the time.

The first phase, JRL west, consists of ten stations from Choa Chu Kang to Bahar Junction and two branches to Tawas and Boon Lay.

[16][17] However, the restrictions on construction due to the COVID-19 pandemic has led to delays of the JRL project, with the completion dates pushed by one year.

Plenty of NTU students, while they welcomed the line connection, had commented they would prefer taking a direct bus route when travelling between the school and Boon Lay as they would have to transfer at Bahar Junction.

[20] To construct the line, a multi-storey car park in Choa Chu Kang was acquired along with the partial acquisition of 19 land plots, affecting only ancillary features such as green verges and fences.

[35] In November 2024, the JRL operation contract was awarded to Singapore One Rail (SOR) – a joint venture between ComfortDelGro's SBS Transit and RATP Dev Asia Pacific – for S$750 million.

[36] The partnership will operate the line under an initial nine-year licensing period, with a possible extension of two years granted by the LTA.

[40] On 25 August 2015, transport minister Lui announced the possibility of extending the JRL from Pandan Reservoir to connect with the Circle Line at Haw Par Villa station via the Pasir Panjang area.

[48] In response, Amy Khor, the senior minister of state for transport, said the LTA is still assessing plans for the extension in tandem with projected developments around the area.

[55] Feasibility studies for the West Coast Extension to connect the east branch to the Circle Line at Haw Par Villa are still ongoing as of October 2024.

[29][72] There were plans for a stabling facility near Peng Kang Hill station that would have allowed enhanced launching and withdrawal operations of trains.

[16][74] The JRL is fully automatic, using Siemens' Trainguard Sirius Communications-based train control (CBTC) moving-block signalling system.
