The opening of the Ceneri Base Tunnel in December 2020 will mark the completion of the New Rail Link through the Alps (NRLA), turning the long-held dream of a flat rail link through the Alps into reality. The NRLA provides Switzerland with modern, high-performance rail infrastructure on Europe’s north-south corridor – and an environmentally-friendly alternative to road transport and travel. The opening of the Ceneri Base Tunnel is not just the final part of the Rhine-Alps corridor, an epic feat of engineering, but also a symbol of northern and southern Europe moving closer together. The design of the special stamps highlights this aspect in particular. On the left, a freight train is travelling through the Netherlands. On closer inspection, its destination can be made out – the port of Rotterdam. On the right, a passenger train is arriving in Milan, represented by the world-famous cathedral. The two special stamps are linked by a gutter which shows the Ceneri Base Tunnel. Here the Alps are not a barrier between north and south, but are instead depicted as nature – an allusion to the climate-friendly mobility that the tunnel promotes.
