Yeah, with 3 duties on 920 and 1 duty on 922. During mealbreak
on weekdays for 922 usually one of the 920 duty will cover the 922
duty. For weekends is from 75.
For weekdays, it will be Service 920 doing the supplementary
trip to Service 922.. Not sure if it's still 920AM01 and 920PM02
for weekdays..
Service 75 doing the supplementary trip would be for Service 920
(evening, 75S150, 1 trip @ 6:47pm for weekdays, Saturday morning
would be 4 trips before doing Service 75), and Service 922 for
Sundays morning (9:30am++ trip one)
