Starting on June 4, 2023, 16 new trains will be gradually introduced into passenger service on the North-South and East-West Lines (NSEWL) in Singapore. This is the first batch of the 106 new trains ordered from Alstom and will replace the earliest generation of six-car trains on the line. As the new trains successfully complete testing, approximately two trains will be put into passenger service each month, leading to the phased retirement of trains from the original fleet. All 106 new trains will be fully operational by the end of 2026.

Additionally, the Land Transport Authority (LTA) has procured six additional trains for the Northeast Line (NEL) and 23 new trains for the Circle Line (CCL) from Alstom. These trains will accommodate for the increased capacity when the North East Line Extension (NELe) and the Circle Line 6 (CCL6) commence operations.

The LTA has already completed testing on the six new NEL trains and will hand them over to SBS Transit (SBST) for further operational testing. Out of the 23 CCL trains ordered, two have been delivered and will be transported to the Integrated Train Testing Centre to initiate testing and commissioning in late June 2023.
