(DETRAIN AT TANAH MERAH) SMRT R151 819/820 withdrawn at [EW4/CG] Tanah Merah

Slot 305 is a morning deployment from Tuas West Depot, to do a Full Day Late Night revenue service on the East-West Line on Saturdays.
However, this slot has been rather uncanny on the day itself.
This video shows me catching the first replacement by chance.
1) At [EW4/CG] Tanah Merah, 819/820 dumped all its passengers and was withdrawn into CHD from Platforms C/D, and 063/064 was freshly deployed from CHD to replace it at Platform A towards [EW1] Pasir Ris.
2) 063/064, heading Westbound afterwards, was withdrawn at [EW29] Joo Koon back to TWD and replaced by 059/060.
3) Not long after 059/060 was doing revenue service Eastbound, it was replaced by 509/510 at [EW1] Pasir Ris.
In summary,
305 509/510 FD LN (replaced 059/060; 063/064; 819/820).

So weird

[@USS_BSG75]

0:55 why the door open one side instead of both side like Ang Mo Kio

[@tswub]

So that passengers do not go to the wrong direction, as they are heading towards [EW1] Pasir Ris or alighting at [EW4/CG] Tanah Merah.
