The Community Safety Accreditation Scheme (CSAS) and Railway Safety Accreditation Scheme (RSAS) are initiatives designed to foster partnerships between public and private bodies and the police, enhancing community and railway safety through an additional uniformed presence aimed at reducing crime and anti-social behavior. These schemes require company employees seeking accreditation to be vetted and approved by the Chief Police Officer in their area and to complete specific training, ensuring a qualified workforce committed to safety and security within communities and the rail network.
