In relation to public transport, the Disability Discrimintation Act (DDA) stresses that new vehicles and new stops and stations, as well as those that are being upgraded for reasons including maintenance, network development and operational safety, must meet the needs of passengers with reduced mobility. In such cases, modifications for persons with reduced mobility can be carried out at a reasonable cost. Buildings, equipment and vehicles that cannot be adapted for disabled people easily and inexpensively, must be adapted as part of a special programme (“DDA implementation project”) by the end of 2023 at the latest. The Federal Parliament has earmarked CHF 300 M spread over 20 years to finance such cases. The cantons must also expect additional costs of around CHF 300 M for these special cases. Customer information systems and ticket machines must be adapted in accordance with the law by the end of 2013.
