The S.R.A Law Enforcers


Thousands of commuters travel on the City Rail Network each day. To ensure the safety of passengers and to protect the income of City Rail you will see the "Law Enforcers" throughout the network. These men and women can be seen patrolling the stations and trains and also checking if the passengers hold a current ticket.
There are all different sections that these people work under. They include On Train Security Guards (OTSG), Revenue Protectors, Protective Security Services and more
Most of the radio traffic of the Law Enforcers is heard on the GRN. You can find the GRN frequencies along with other SRA frequencies elsewhere at
