What do “A” and “D” represent on the train arrival screens for trains travelling towards Jurong East on the North-South Line?
These letters represent the platform, which the train would be berthing at, upon arrival at Jurong East interchange. Several trains during the peak hours would typically alternate between berthing at platform A or platforms D/E at Jurong East.
Trains travelling towards platforms D/E at Jurong East are represented by “Jurong East D” on the train arrival screens. Likewise, trains travelling towards platform A at Jurong East are represented by “Jurong East A”.
The benefit of having that information is especially useful for passengers who are heading towards Tuas Link on the East-West Line, as they may choose to only board trains that end at platform D.
This would allow them to simply cross the platform to transfer to trains heading towards Tuas Link at Jurong East, as opposed to taking a relatively longer route to transfer from platform A to platform F, by going through the concourse level.
