[Slow & Delayed Faulty PSD] KSF C151A (559/560) from NS19 Toa Payoh to NS20 Novena

I've seen multiple Full-height Platform Screen Doors (FHPSD), which are seen in underground stations, facing common issues like having to reopen slightly a few times due to some doors being unable to close properly. This issue somehow mainly happens on the North-South & East West Lines (NSEWL). However this time, a PSD at platform B of Novena station, specifically at door 16, seems to be experiencing a different issue where its doors are way more unsynched and delayed when it opens and closes compared to the rest of the other doors. At timestamp 2:00, you can see that when the train doors of trainset 559/560 were fully opened, the PSD still remained closed momentarily until it shortly opened afterwards but very slowly. At timestamp 2:24, you can also see the PSD closing very slowly compared to the other doors as seen from the overhead orange indicator lights above each PSD, where all of them have been turned off except for door 16 which was still slowly closing even after the train doors have fully closed. Honestly, I've seen this kind of thing happening a few times with the Half-height Platform Screen Doors (HHPSD) for the overground stations on the NSEWL, more commonly for door 24 which is the last door located at the back of a platform. I don't know why but I used to see them facing delayed door openings compared to the rest of the other doors for some reason haha. I just decided to film this for fun since it was kind of rare for me to see this kind of slow and delayed door opening and closing for the FHPSDs in underground stations. _________________________________________________ Train model: C151A Train set: 559/560 Train run number: 203 Recording device: Samsung S25 Ultra All train footages were solely recorded and copyrighted by ‎‎‪@papaguette‬.
