Katia, 26, and Cyril, 24, are train drivers in Alsace, France. They met on Twitter after Cyril was transferred to Strasbourg.

Cyril likes to photograph trains; Katia has just moved to Mulhouse and is looking to make friends. But everyday life is not always so rosy: “One day, someone tried to throw themselves under my train,” says Cyril seriously. “I experience harassment on a daily basis, especially certain colleagues,’ says Katia.
