The London TFL Dot Matrix Typeface is a set of dot matrix fonts that replicate the styles used on TFL’s Underground network arrival boards and rolling stock led announcement boards. The font set includes four different weights, each representing a specific typeface. The typefaces come in various character sets, including upper and lower cases, numbers, and symbols. However, some characters are unverified, and the creator requests anyone with photographic evidence to contact them on Twitter. The typeface is distributed under the SIL Open Font License and can be built upon using Adobe Illustrator templates and FontForge.
