Constructed on the former site of the Raffles Country Club and opposite Tuas Depot, the 50 ha (120-acre) SRTC will be used to test new rolling stock and rail systems for the Singapore MRT network.

Hailing it as a "worthwhile investment" expected to cost a few hundred million dollars, Khaw said that the ITTC will allow "robust" testing of new railway systems without the need to close MRT lines.

[16][17][18] The SRTC is constructed on the former site of the Raffles Country Club in Tuas, which was originally acquired for the planned Kuala Lumpur–Singapore high-speed rail.

[5] The SRTC will have 11 kilometres (6.8 miles) of track, which will be compatible with various types of signalling systems and will be powered by both 750V direct-current third rail and 25kV alternate current overhead catenary.

[11] As a shared testing and maintenance centre, the SRTC also aims for LTA engineers to collaborate with train operators and equipment manufacturers to improve rail capabilities in Singapore.
