Amendments to safety regulations

Incident reports, the results of audits and operating inspections and the findings from preventive checks are all systematically evaluated and form the basis for improvements to the applicable safety regulations and standards. The FOT thus continually updates its public transport safety standards in line with increasingly stringent requirements to ensure the public transport safety for which Switzerland is renowned. The same rules apply without exception to all operators and organisations involved in the country's public transport system. Any other approach would not only jeopardise safety; it would also distort the competition among the various public transport providers.
