Suspect:
SBS1874P: BBDEP 92
BBDEP 92A/ 200 (x-over)
Seen service guides of Sv 74 and Sv 200 inside the bus before when
i took it for a joyride up Mount Sinai a few weeks back. It was on
92, not 92A.
However, I have seen it on several ocassions as 200, most of the
time on peak hours. Suspect it could be an extra bus during the
peak hours. Today when i was in the Dover vicinity. I saw SBS1724P,
SBS1839S, SBS1895D as well as SBS1874P most of the time. Thus, i
presume it is a peak hour crossover.
Since most people say that MK2 NAC never do the full 92 route.
Thus, my guess is that SBS1874P serves 200 during the peak hours,
doing x-over from 92. It serves 92A then during the non peak hours.
My guess, so possible not true
