if is BBDEP the 1st depot to get it massively, they might kick
out some VO3x then send to SLBP, while the leylands are going to
lay up by then.
just like how they did for last time when ComfortDelgro bodied
B9s came in.
nothing is for sure.
there may be major cross-deployments taking place as well
like VOs from HG or BB going SL and etc
meanwhile, if these new buses come in. they'd better be
maintained properly
