X-trafik is a train operator in Sweden. X is the code that was used for the county (län) of Gävleborg in a time (1907–1973) when all counties were coded with a single letter (and in one case, two letters). More info on the county letter codes on the Swedish Wikipedia page.
Where most other logos of train or other public transport operators have rather boring sans serif fonts, I love how X-trafik chose the playful FF Cocon for their logo. Although the official name seems to have the dash, the logo and trains are without the dash. The logo was introduced in late 2008, replacing the previous version in bold italic caps from Futura.
X-trafik use the typeface also at the front and at the sides of the trains saying “Xtåget” (meaning “the X train“), and there is a large X in FF Cocon on the side of the trains and buses. (There is no “Xbuss” on the bus, though.) The red X is used as the favicon on the website and as the logo for the mobile apps.
X-trafik is run by and under the responsibility of Region Gävleborg, the county government. More info in Swedish is available on Wikipedia.
