East of FP, I believe maspeth/arch st. etc is 'as needed' though they seem to be in maspeth at least 2 or 3 times during weekday afternoons. I've never seen them switch the stone customer though, so my theory is that happens early in the morning or at night. East of maspeth there's just arch st. & allied - probably once, twice a week? It'll be a 5-6 day a week operation when the MSW starts moving.
No idea about bay ridge. I've seen that move maybe twice over 10 years, in the evening both times.
They work bushwick at least 5 nights a week, though I believe they drop empty msw cars there in the morning too on occasion. They go all the way down to morgan ave a bit less than to the small yard at varick where the trash is picked up / dropped off.
West of FP: There's the train for the central branch, but there's also whatever goes to huntington... Same crew, different days?
I think there's a 'schedule' in old threads on here but I've never known what symbol goes to what branch at what time...
