One of the great things about Switzerland is its passenger rail system. Service is frequent and convenient, and the network is dense so you can get almost anywhere in the country by train. And you can even ride the rails high into the Alps on the many cog wheel railways and funiculars. But Swiss railways really outdid themselves with this rail service diagram. If you download the full sized version (and you should) and zoom in, you will see that the diagram contains train arrival times for every station pictured (for those train services that run daily). With only a copy of this diagram you’d have all the information you needed to navigate the entire Swiss rail network, although you might need a magnifying glass to read the small print. The Human Transit blog explains how to read the notation.
