[CCL6 Open House; Withdrawal + Horn!] ALS C851E (877) from CC30 Keppel to CC32 Prince Edward Road

I was planning to film a tunnel view ride from Keppel to Prince Edward Road station when suddenly a loud random alarm was being sounded shortly after departing Cantonment station. The alarm then played again moments before arriving Prince Edward Road station. The train was actually withdrawing from service temporarily at Prince Edward Road station while another C851E trainset 883 took over in its place for the shuttle train between PER & KPL. Surprisingly, I also caught the C851E horn at 4:24 right after the train stopped at the station, it kinda sounded like a KSF horn ngl haha. _________________________________________________ Train model: C851E Train set: 877 Train run number: 866 Recording device: Samsung S25 Ultra All train footages were solely recorded and copyrighted by ‎‎‪@papaguette‬.
