The British Rail typeface, also known as the Rail Alphabet, is a distinctive sans-serif font that has been a visual hallmark of the UK's railway network for over six decades. Designed in 1958 by J. R. Holmes, a British typographer and lettering artist, this iconic typeface was commissioned by British Railways (now known as Network Rail) to create a unified brand identity for the organization.

Although British Rail was privatized in the 1990s, the typeface continued to be used by various railway operators in the UK. In recent years, there has been a renewed interest in the British Rail typeface, with many designers and typographers advocating for its revival. In 2019, a digital version of the font, called "Rail Alphabet," was released, allowing designers to use the iconic typeface in digital projects.
