[Whiny Motor] ALS R151 (849/850) from NS13 Yishun to NS16 Ang Mo Kio

I initially filmed this video to test out my new phone camera, since my old phone had too many "green lines" covering the screen for me to even use it anymore. In this video, I decided to film the whiny motor on trainset 849/850 at car 11850 door A4 which I personally kinda like it. The whiny motor is still present as of date of upload of this video. _________________________________________________ Train model: R151 Train set: 849/850 Train run number: 233 Recording device: Samsung S25 Ultra All train footages were solely recorded and copyrighted by ‎‎‪@papaguette‬.
