Four people have been charged during a police operation run on trains between Wolli Creek and Cronulla.
Operation Blueline, held on Thursday, is designed to stop crime and anti-social behaviour on trains.
Police Transport Command officers patrolled stations throughout the day and were joined by their colleagues from St George, Sutherland and Miranda.
More than 58 trains were patrolled, 13 people were searched, 19 move-on directions were issued and 54 transport infringements issued.
Police also made four arrests for goods in custody, possession of a prohibited drug and transport offences.
Police Transport Command Chief Inspector Craig James said police will continue to focus on reducing crime on public transport.
“People should feel safe and secure while using public transport in the Sutherland Shire and George’s River district,” he said said.
“The Police Transport Command will continue to focus its attention on anti-social behaviour especially throughout the warmer months of the year.’’
