The best logos tend to be simple, memorable and versatile. Some are so versatile they can be put to uses the original designer never imagined. That’s the case of San Francisco’s ‘worm’, as the logo of the city and county’s municipal transport network is affectionately known.
The San Franciso Municipal Railway’s classic wiggly logo is the star of a new ad campaign in which its distinctive form is used to represent more than the network’s train lines and its abbreviated name – muni. Some think the campaign is ingenious design, but not everyone agrees. In fact, some are arguing that even the original logo is a stinker. But even it does break some of the rules of how to design a logo. But does that really matter?
The Muni logo is often hailed as a design classic. Created by Walter Landor in 1975, it represents transport lines but also spells out the network’s abbreviated name. And while it’s clearly a product of its era, with smooth, almost psychedelic lines reminiscent of the early 70s, it’s stood the test of time. It proved iconic enough to resist change when the SF Municipal Transportation Agency (SFMTA) was created in 1999 and it remains in use today.
Now a new campaign cleverly reworks the Muni logo into different shapes. The “Muni Moves You!” campaign is designed to draw commuters back to the network in the wake of the Covid-19 pandemic with print and digital ads that see the abstract Muni worm morph into icons representing noodles, art, dating and shopping (see below).

The designs have been delighting many in Reddit’s r/DesignPorn (opens in new tab) community – particularly people who know San Francisco. However, others have rubbished both the new designs and the original logo, describing the former as “confusing” and the logo as “unreadable”. One person has pointed out that the ramen icon looks like a toilet.
“Seriously, what is this supposed to be?” one person asked. “That logo is horribly unreadable,” someone else protested. Even some San Franciscans admit that they never realized the original logo was supposed to spell ‘Muni’.
The debate raises some interesting questions about logo design. I’d usually agree that readability should be a primary goal – unless you’re designing for a metal band. But should we always be so prescriptive?
Perhaps you have to know San Francisco to make the connection and understand the new ads, but then the campaign is entirely at San Francisco residents who’ve seen the Muni logo for decades and will immediately recognize it in the new icons through the forms and the colors. “To San Franciscans (like me), the Muni logo is everywhere,” one San Franciscan has pointed out in the debate on Reddit. “The tie-in was obvious and fun.”
As for the original logo, we’ve been quick to criticise logo designs for a lack of readability on occasion, but I wonder if it really matters here. A logo represents a brand, not a word. Those that don’t see the ‘Muni’ in the design, simply take the logo to represent a public transport system, which is what it is. The ‘Muni’ hiding in there is almost a bonus, like in several logos with a hidden meaning. Sometimes the rules can be broken and still result in a classic design, otherwise, people start asking why all logos look the same.
