Two of the new trains are also fitted with an automatic track inspection system, the first trains on the North-East Line to have them.
This system monitors track conditions while the trains are at work via cameras and sensors installed on the underframe of the vehicle.
“This will improve detection of track defects, such as rail cracks, rail corrugation and missing rail fasteners,” said LTA in the press release.
The six new trains were manufactured and assembled by Alstom in Barcelona, Spain. They arrived in April 2021 and have been undergoing testing since then.
In addition to the new trains, LTA added that the mid-life upgrade of the 25 first-generation North-East Line trains is “progressing smoothly”.
Four trains have been upgraded so far, and the remaining ones will be progressively upgraded by 2026. They will get newly renovated interiors, as well as new condition-monitoring capabilities and air-conditioning and ventilation systems.
