“Designed by Margaret Calvert of Kinneir Calvert Associates in the early Sixties. Originally drawn in two versions [for positive and negative use], as a constituent part of an integral signing system, it first appeared in the United Kingdom’s National Health hospitals and, subsequently, British Rail and Danish Rail stations, followed by all BAA airports.” [A2-Type]
Best known for its use in the signing system for British Rail which Calvert designed together with Jock Kinneir in 1965, as part of the new visual identity program coordinated by the Design Research Unit. Replaced Gill Sans on British rail station signs. Also used for lettering and numbers on and inside trains, trackside notices, letterheads, timetables, posters, etc. [The Beauty of Transport] Adopted by Danish State Railway (DSB), where it was replaced in 1997 by Via.
“In Britain, Kinneir Calvert’s sign system began to disappear in the 1990s, as British Rail was privatised and split into smaller companies, each with its own logo and type. Station signs, the responsibility of Railtrack (the group in charge of the infrastructure), were eventually replaced by The Foundry’s custom typeface Brunel.” [Eye, 2009]
Revised by Henrik Kubel in close collaboration with Margaret Calvert and released as New Rail Alphabet for general licensing, expanding the design to 6 weights plus italics, with a much larger character set. Despite small differences, this version is used for the sample.
