Officers from the Transit Safety Division conducted the operation last Thursday to detect weapons offences and enhance community safety.
Six people were arrested for a range of offences including carrying a concealed weapon, stating a false name, assault and being wanted on warrant.
Five of those arrested were charged on summons and will appear before court at a later date, the sixth was issued with a caution.
“In an ideal world, we would never have to run these operations, but the reality is a small number of people choose to carry weapons,” Transit West Inspector Fiona Curnow said.
“Our message is clear: we simply won’t tolerate it,” she said.
