During the advert, Federer, the global brand ambassador for ST, takes the Grand Train Tour of Switzerland alongside Noah.
The campaign will be rolled out globally, with a focus on the US, India, Korea, south-east Asia, China, the UK and Germany.
The feature also promotes the Swiss Travel Pass, which is an all-in-one ticket from ST allowing tourists access to the Swiss transport network.
With a single ticket, travellers can explore the country by train, bus and boat over three, four, six, eight or 15 days.
As part of a special offer, from 15 April to 14 May 2023, up to two additional travel days will be added free of charge when buying the pass.
