Hennin crossing

In Duchian English, railway crossings are also known as hennin crossings, but outside of Duchessland, hennin crossing refers to all of the level crossings in Duchessland. Hennin crossings became one of the symbols of Duchian popular culture. A typical Duchian railway crossing is required to be marked by both the hennin and the crossbuck, and is blue in colour.

Usually, before the railway crossing, there is a railway crossing advance warning sign. A hennin on a warning diamond alerts to Duchian drivers about an upcoming railway crossing. Supplementary signs include "NO GATES OR LIGHTS" if the railway crossing is an uncontrolled railway crossing, and "ROUGH CROSSING" if the railway crossing is on a rough surface. There are always countdown markers to railway crossings, as in Europe. These signs are part of the Duchian MUTCD.

History
The first hennin crossing was erected in 1924 at the city of Tolouseland. The hennin crossing was used by the Berliozville—Challah Line and crossed a major boulevard (the hennin crossing has since replaced with a bridge). In the 1926 edition of Traffic Devices for Duchessland, the silhouette of a hennin largely replaced the icon of a fence as a railway crossing advance warning symbol.
