instead of guessing the rego why not consider
1. where did the news team shoot the bus
2. WT13 is under which depot
Q2 being more impt as it will narrow you down to only 2
buses.
1st point is at AMDEP which I said AMDEP/KJDEP earlier on. Even
if WT13 is under AMDEP, sometimes the SL might key in wrongly?
