At Stadler Rail in Bussnang, a wooden model of a new generation of S-Bahn trains for Regional Verkehr Bern-Solothurn (RBS) is currently being built. From 2018, the new “Mandarinli” (or ‘little mandarin’) will enter revenue service on line S7, replacing rolling stock from the seventies.
With the mock-up in Bussnang, the interior design of the new RBS trains is being evaluated, because nothing can beat a 1:1 scale tangible model when it comes down to validating spatial experience and practicality. Train drivers, passengers, representatives of the association for disabled people, all stakeholders will get a chance to refelct on the proposed design. If needed, modifications can be implemented before the first final product is being built.
In 2016, RBS ordered fourteen new 4-car EMUs for an amount of 134 million Swiss francs. Design agency Tricon made a vehicle design for RBS, before a tender was issued to find a manufacturer. An extra challenge for Stadler Rail, that has to develop a custom-made design.
