While Transport has since been an enduring success on road signs, it was designed around the specific needs of road users - such as visibility at speed and in all weathers.

In the early 1960s, British Rail trialled new signs at Coventry station that made use of Kinneir and Calvert's recently launched Transport typeface. This style persisted for nearly 15 years. Lettering was to use redrawn versions of Gill Sans lettering on a background of the regional colour. In 1949 the Railway Executive decided on standard types of signs to be used at all stations. The font was designed specifically for signage and the designers included features to support this such as a bespoke letter-spacing system and two slightly different weights to provide optimum visibility on both light and dark backgrounds. The font also has some similarities to Akzidenz-Grotesk, which had earlier provided the same designers the broad inspiration for the Transport typeface used for road signs in the United Kingdom. Rail Alphabet is similar to a bold weight of Helvetica, but with some differences in character shapes, stroke width and x-height to aid legibility. , whilst the BR 'double arrow' logo will also be restored as the primary brand identifier for the network. ДЄ modernised font Rail Alphabet 2 is planned to be used across the Great British Railways network.

First used at Liverpool Street station, it was then adopted by the Design Research Unit (DRU) as part of their comprehensive 1965 rebranding of the company. Rail Alphabet is a typeface designed by Jock Kinneir and Margaret Calvert for signage on the British Rail network. Rail Alphabet in use at Castle Cary railway station
