Variations of the letter M... and other metro logos of the world.
How to find the subway? Nearly all metros have logos or symbols marking their station entrances and rolling stock, as well as printed matter, such as maps or tickets. The logos vary widely across the globe. Since most metros around the world are indeed called 'metro', quite a bunch of the logos are more or less fancy variations of the letter M. (Fewer metros are called 'subway', 'underground', 'U-Bahn', 'T-bana' or something completely different.)
193 metro logos, sorted by city
There are different kinds of metro logos: In some cities, a logo stands for the metro system itself, while in others, logos represent one or several operating companies. So there may be more than one logo in one city, while in another, a logo can consistently stand for the system.
Some logos are ubiquitous, at least nationwide:
Germany: all metros use a blue U logo (LRTs have slightly derived ones). Suburban railways use a green S logo.
Italy: most cities use a white letter M on a red square for metros.
Spain: most suburban railways (called Cercanias) bear the same red C logo.
Former Soviet Union: many cities are using derived versions of a red sloped letter M for their metros.
Due to the significant differences in usage, this list can merely give a rough overview. If a city uses a logo for the metro system itself, the list will prefer it over company logos.
