Anyway, SBS9177R is back out to AM SP from AM 13? I thought
someone posted before that it had a Sv 13 perm stix? 
From what I see everyday, there will be at least 2 SP LO3Xs on
sv13 replacing some of the double deckers. So far I have not seen
9177R doing it these past few weeks. So far I've been seeing all of
its DDs almost everyday and the LO3X that cameos on it is 9045M,
9194R, 9141T to name a few.
More often that not, it does sv25 in the morning, sv72, sv166
etc. There isnt any SD to DD conversion slot on sv13 so far I have
seen. Same for sv55, but this when 9449G went in, 9378C went
missing since now sv55 has an extra bus.
