SBS209S
(BRBP 139 
Awaiting De-registration)
SBS464X
(BRBP 63 BRBP 139)
SBS2689B
(BRBP SP BRBP 63)
no more SP MK IV in BR (:
1) According to Businfohub redeployment list,
SBS209S is replaced by SBS494J,
however, the above past redeployment shows
SBS464X. So which is the correct one? Service 139 has 1 extra bus according to
Sgwiki now.
2) Also, any bus replaces SBS287R on Service 59 and SBS8817J
on Service 231?
