Those buses were spotted with the 159 service guide cut out.
Perhaps its like the same case as some other DM3500s
(like SBS2833B,
which had 3 of them), but
stayed as spare until some other buses were transferred out of
159.
Maybe SBS6125K and SBS6197C are due to be transferred out
once their ad contracts expire? Or perhaps some other buses are
also due to be transferred out.
I'm currently confirming the fleet of 159, buses currently
spotted are: SBS1967E, SBS1994B, SBS2636D, SBS2761A, SBS2772T,
SBS2813J, SBS2833B, SBS6125K, SBS6197C.
SBS2745Y and SBS2751A (the new additions) are still spotted
running around on other services, same case as the to be 159
permers a few months ago.
so messy bus deployment on 159 at the moment ! even like 8622
out of 159 still now still hv perm 159 sticker and cut out 159 svc
guide on bus .
