SBS2723K (HG SP)
got 159 perm svc guide cutouts. It was on 43 today though. But why
suddenly more and more buses got the 159 svc guide cutouts?
Somemore 159 already got 3 extra buses already.
According to my observations, these are the missing buses on
159: SBS2733G SBS2745Y SBS2751D SBS2766L SBS2824C SBS6400R. I only
spotted 19 buses running, is there a reduced fleet during ITE
holidays?.
I have spotted SBS2733G, SBS2745Y SBS2751D running on
other services a few times already, suspect these buses are still
spare. And SBS6400R does not even seem to appear on 159 at
all.

i think whenever this buses cameoed on 159 they SL just go
slot/pasted the 159 svc guide on the buses only so dat y suddenly
happened so many buses go perm this svc haha... 

btw for 6400R yup ! was not doing on this svc at all now just
saw a few times on 100 116 158 this svcs
