Basically, there isn't any trial for VSOs to be sub buses for
services that use Double Decks. If it's a bus that is not utilise
on that day, it can be taken out and operate on another service,
whereby its bus(es) may have gone for maintenance, or broke down.
Such operation is a norm to any bus operators.
Regarding to depot changes for the 2 interchanges, I feel that SBST
per se is trying to group their bus interchanges with accordance to
the NEL. There was one newspaper article (around 1999) stated that
if SBST takes over NEL, its benefits would be to rationalise both
Bus and Rail, which was happened in July 2003, and now, depot
transfers.
