This video features a KHI C151, 079/080, which is from Kranji to serve NSL for the whole day, only to swap with 675/676 to an AM Withdrawal Run, from NS7 Kranji to NS9 Woodlands. Seems that 079/080 is suffering from some regenerative braking issue where thee regen brake is inconsistent. Throughout the whole journey that I was on 079/080, it keeps on using friction brake for some reasons... For this video, you caan see that 079/080 uses friction brakes when it arrived at Marsiling (when you can't hear the strong deceleration that was present) and some uses normal braking when arriving at Woodlands (when you can hear the strong deceleration present)). Interesting... Strong Motor +Flatwheels can be heard on car 1079 A4/B4. Since 080F leads, strong deceleration can be heard.

Eventually, this would be the last time that 079/080 appears on NSL after swapping to Run 218 AM Peak to UPD, and would randomly appear on EWL a few days later.
