Burke and McLaren – LONDONS PUBLIC TRANSPORT DIAGRAMS 1981

Description

This article by Michael Burke and Ian McLaren reviews and compares graphic conventions used in public-transport diagrams for greater London, highlighting fundamental differences between rail and bus mapping. Rail maps—exemplified by Harry Beck’s seminal topological underground diagram—favor schematic, topological geometry and have evolved varied interchange and station symbols, while bus/tram maps are more topographic, reflecting street-level experience and denser interconnections. Several British Rail diagrams are praised for encoding service frequency via station symbols; others suffer loss of clarity when converted between colour and monochrome or when overly decorative elements are used. Beck’s 1938 proposal to unify London Transport and British Rail cartography was never adopted, and comprehensive integrated maps remain lacking, causing potential confusion for users. The authors note recent electronic display innovations and argue that despite long-standing attempts, insufficient effort has been made to reconcile rail and bus cartographic identities into a coherent, user-friendly system.
