They actually purchased 1400 buses bet 1988 and 1993... This is
excluding the 200 Superbuses that's introduced in late 1993
Of which alrdy 200 has been replaced by the double decks and
they'll leave mostly at the end of this year... The remaining 1200
would be replaced now, starting with 100 of them
So cos of the max 19 year usage, the mass purchase is starting
again
