may be because @ dat time AMDEP/ BR hv take in
500+ kubs to replace their old buses already ! and
now AMDEP almost all svc cover by kubs and some citaros !
At that time AMDEP/BRBP/SLBP got hundreds of 0405s to clear off
so the K230UBs were meant for fleet renewal down there.
Whereas for now it is the MK3s turn to be
replaced, so this time round HGDEP/BNDEP/ARBP/BBDEP got to take in
the Citaros.
