Muni's iconic "worm" logo was designed by Walter Landor in the 1970s and is still with us today. It's a love-it-or-hate-it kind of logo, but it will never be mistaken for the municipal railway logo of any other city than San Francisco. For better of worse it's distinctive and memorable. That's probably why no one has tried to redesign it, even though it's obviously a product of its time and has not aged in a timeless looks-modern-even-though-it's-not way.
I remember seeing the logo as a child. It took a long time before I realized it was spelling out a word, and I was so struck by it that I remember wondering how many other people had figured it out.
If you grew up in San Francisco in the '70s it was just part of the identity of the city.
It's been parodied, bashed and lovingly commemorated in equal measure. San Francisco apparel company 4fifteen, named for the city's 415 area code, even made a "Muni Driver" cap that uses a "worm" version of its logo and only comes in the classic Muni uniform color combination of brown and orange.
Well, thanks to Metrobits.org, which compiled transit and subway system logos from around the world, I can finally compare Muni to other logos and pick out some of my favorite domestic and international transit logos.
Best American transit logos
Most transit logos (even the international ones) use an "M" as the mainstay of their logos, so it's hard to find logos that don't look generic. Here are some of the more distinctive American logos.
Each is successful mostly because of its simplicity and clarity. SEPTA and New York make use of diagonal emphasis to give a sense of movement, which is another plus.
Best abstract concepts
Like the Las Vegas logo, some transit logos take a conceptual approach and don't include any acronyms or letters to explain themselves.
Most of these logos get their abstraction from suggesting forward motion or moving to and fro. Some abstract the path or tracks, with Yokahama getting especially nice synergy between the intersecting tracks and the letter "Y."
Most interesting variations on the letter "M"
Since the underground is referred to as the metro in most languages, the "M" is a common theme. These are the logos that really explore the graphic possibilities of the letter "M."
A few of these make the "M" a dimensional object looping in on itself or take the idea of tracks and separate out the "M" into segments separated by a thin white line "track." It's a great creative approach to take the letterform and tie it to a concept like motion or make it evoke a physical object like a set of tracks converging.
As far as I'm concerned, Muni still comes out on top.
