"In 1980, Josef Müller-Brockmann laid the cornerstone for a uniform visual identity for the Swiss Federal Railways (SBB) with his legendary Visual Information System at Train Stations and Stops. In view of Switzerland’s multilingualism, the manual proposed a signage system that largely did without language; with his functional typography, the pioneer of Swiss graphics conceived an intuitively comprehensible signage system for use throughout the country to also guide passengers unfamiliar with the terrain to their destination by way of pictograms. The visual concept was developed in dialogue with the SBB and still dominates the railways' visual identity even today."
