It is still 6-7 mins frequency. There is no 5.5 mins. For
off-peak it works at 3.5 min on average, usually 2 min then 4
min then 2 min. Due to the demand still not very high, some parts
may be 5 or 6 mins during peak. Frequency was reviewed a long time
ago, just that that was for peak only.
EWL peak hr freq is equal being at 6 mins at e most less peak
time.
This was wat I saw and observed at around 1pm ytd.
