London Tube by Jonathan Paterson is a free Johnston-style sans serif drawn from the spirit of London Transport lettering. The letters feel calm and unmistakably metropolitan, with broad round forms and clean strokes that give the font a measured, civic voice rather than a neutral modern one.
It fits naturally in posters, wayfinding-inspired branding, editorial cover lines, museum graphics, and title cards where that early transit character matters. As a free font, it also works well for logos and short headings, because the rounded geometry and plainspoken rhythm carry the look of public signage without becoming stiff.
