Wales' longest station name: How it got its name, and what it means. TAKE a deep breath and say it with me: Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch. No, I didn't just drop something on the keyboard, that is the actual name of a train station in Anglesey, serving the village of Llanfairpwllgwyngyll.
