SMB209B went to 188, so could one of the O405s become its
replacement?
There is NO replacement for SMB209B on 307. Last time it is an
extra bus, meaning at any one day, at least one MAN will not be on
307 since its BC are on rest day. For example, for mondays, 307AP02
will be on rest, So SMB209B will do 307AP02, while the original bus
on that duty for the week, say SMB214K, will become spare and go
other svcs. Tuesday SMB209B will do 307AP03 while SMB214K will do
back 307AP02.
For now, the perm BCs for SMB209B will drive the MAN that is
supposed to have its BC having rest day. For example, tomorrow
(2/6), BCs for SMB215H are on rest so SMB209B BCs will drive it, on
tuesday (3/6) BCs for SMB210X are on rest so SMB209B BCs will
drive it etc...
