On 9 May 2018, the Land Transport Authority (LTA) announced that a joint rail and bus depot in the Tengah area will serve the proposed Jurong Region line (JRL).

[1][2] However, the restrictions on construction due to the COVID-19 pandemic in Singapore has led to delays, with the completion date pushed by one year to 2027.

[3] Contract J101 for the construction of Tengah Depot and its associated facilities was awarded to China Railway 11 Bureau Group Corporation (Singapore Branch) at S$739.5 million in November 2019.

Within the site will be a four-storey transport workers' dormitory which can accommodate 450 bus captains.
