I love the work Eden Spiekermann did with the DB house font (http://edenspiekermann.com/en/work/projects/deutsche-bahn). One might even go as far to say that I would travel to Germany just to see it in use. But I was wondering whether there were any "alternatives" (specifically to the sans-serif face)? By "alternatives" I don't mean copies, but rather faces that follow a similar set of principles. For instance, I would consider Forza (http://www.typography.com/fonts/font_overview.php?productLineID=100041) by Hoefler & Frere-Jones to be along similar lines... it's refined, quite "square", the wonderful way that strokes meet vertical strokes by thinning etc etc.
Is there anything that springs to mind?
