Yes, that's Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch. At 58 letters the longest place name in Europe and, presumably, the longest railway station name too.
This town is in Anglesey, an island just off the north west of Wales, and most people here speak Welsh fluently. The name of the town was extended to its current length in an attempt to boost tourism as long ago as the 1860s. This translates into English as 'The church of St. Mary in the hollow of white hazel trees near the rapid whirlpool by St. Tysilio's of the red cave'.
We stopped by during a recent short holiday in Anglesey. There wasn't much danger of taking the train here though, they only come by once every couple of hours or so.
