The roundel design first appeared at Underground stations in the early 1900s.
Each of our transport divisions, or modes, has its own roundel. These communicate that while they are part of TfL, they also operate independently.
Strict rules exist about how the roundel can be implemented, and copyright exists on its reproduction. Only name/words (companies, stations etc.) already used by TfL can be written through the bar of the logo and any third party wishing to reproduce any of these logos must first seek the written authority of TfL.
