British Rail Alphabet (1965)
"New Rail Alphabet is a revival of the British Rail alphabet designed by Margaret Calvert of Kinneir Calvert Associates in the early Sixties. Originally drawn in two versions, 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. Now produced in six weights, Off White, White, Light, Medium, Bold and Black, with non-aligning numerals, corresponding italics, and a subset of Eastern European characters."— https://www.typeroom.eu/woman-of-type-design-museum-margaret-calvert-rail-alphabet-2-typeface
