SBS8030L, SBS8033D, the Sunlong hybrids (SBS8000Z and SBS8001X)
and this bus (SBS8002T) are/were under Soon Lee Bus Park (SLBP)...
Seems likes it is the depot for the new demonstator buses (except
the Volvo B9TL Wrights).
It's not so much about the depot but the routes. This bus serves
almost identical routes to the Sunlongs last time..which IMO, might
be their way of comparing the hybrid capabilities of the Volvo
system vs the Sunlong system.
And anyway, I think you forgot 7888K. That's a Scania demo
that's not under SLBP. Haha.
