StateRail has invested significantly over the last five years in passenger safety and security. Security guards on trains from 7.00 pm were introduced in 1998. More recently, additional lighting, 5,700 closed circuit television cameras (CCTV) and emergency help points have been installed on CityRail stations. In addition, CityRail has employed some 100 transit officers to patrol its network and intends to employ another 200 transit officers in 2003. While substantial steps have been taken to reduce crime and improve passenger safety and security, the results have been mixed. Overall, the risk of a passenger becoming a victim of a crime on CityRail has increased.
