This Amsterdam Railway System map takes a motif from tulip, the Dutch symbol. With the Centraal Station at the centre, lines of tram, metro, & railway spreads out like the stamen & pistil of the flower. The IJssel (Het IJ, river) forms the petals, & layers of fan-shaped canals complete the tulip. City Railway System is a new approach to projecting the identity of a city onto its subway map. Whereas conventional subway maps aim at conveying information as clearly & concisely as possible, the City Railway System by Zero Per Zero instinctively incorporates symbolic elements of each city into its map while preserving clarity. As a special consideration for tourists, major landmarks & tourist attractions are indicated on the subway maps, so that tourists can easily figure out the quickest way to get to the destination at a glance. The railway map itself is also good as a souvenir.
