Stroudley is a sans-serif typeface, created in 1996 by Dalton Maag as commissioned by Kowloon-Canton Railway Corporation (KCRC), a transit operator in Hong Kong, for use on the corporate identity of its railway system; the version used by the rail company was named Casey.

Dalton Maag later amended Casey and released it as a commercial font named "Stroudley".

[1] Stroudley then served as a template for the Barlow typeface made for the signage at London St Pancras International station.

When the KCR West Rail (now Tuen Ma Line with merger of Ma On Shan Rail) started operation, its usage expanded to all signage and station nameboards in the WR stations, and even became the font used in the leaflets and brochures distributed by the Corporation.

In 2019, the font began its usage in the public transport system of Singapore, first introduced during the opening of Canberra MRT station and Thomson–East Coast MRT line, replacing the previous font, Ocean Sans.
