POLARIS is the abbreviation for POpular LAndscape Railway In Switzerland. The trains are particularly accessible and customer-friendly. With low-floor entrances and a modern customer information system, the new models also make travel faster and smoother. The new double railcars are compatible with the current fleet's trains, allowing them to be combined in multiple units in the future. New multi-purpose areas also offer more storage space for sports equipment. The modern exterior and interior design was developed by the renowned Italian design studio Pininfarina.
