SBS9590E did went to SLBP do 97. Several LO3x like SBS9080K,
SBS9081H, SBS9083C were sent to BBDEP to do svcs like 99, 165 and
198.
Most of the BBDEP Mk4s (eg SBS2653D) went to SLBP to do 502.
Existing SLBP Mk4s in SLBP mainly from 66 and 105 also did 502
during that period.
Basically, there was a switch of SD/DD buses between BBDEP/SLBP,
BRBP/BNDEP and HGDEP/AMDEP during the IMF period in 2006.
SBS9083C is a BRBP bus, you mean SBS9082E?
The perm 502 Merczs were also spread around BBDEP services.
Last 3 days before IMF ended, SBS3733A and SBS3735U did cameo on
198. But I am not sure about the rest.
SBS1960Z MIAed on 99 (But it was not x-fered as I could see it
doing 99 before IMF ends). In fact, I could see all of 97 permers
did 99/198.
SBS2698A, SBS2762Y should be serving for IMF shuttle as they got
the DBS bank ad.
To conclude, BBDEP got 97/179 permers and SP buses. SBS9024Z and
SBS9031C cameoed on 198. SBS9080K and SBS9098K did 99.
