don't think so, 161 has only 2 SD left, if these two are
redeployed and replaced with DDs, its high likely it will revert
back to SD, demands are high on 161, especially peak hours. a SD
can't do really much especially then. once, a DM3500 (think SBS
2836T) came, can't even board, in the end have to take the next
bus. another one time was when SBS 9808D came, it was almost full,
but luckily until near exit.
