A quiet train station in Tsuruga, Fukui Prefecture, has become a mecca for train spotters, known as "tet-chan" in Japanese.
Whenever a dark-green train called the Twilight Express sleeper service pulls in at Tsuruga Station on the Hokuriku Line, many passengers hop off to take photos of the locomotive being switched for another engine.
Because it is a long-distance train, the locomotive added at Tsuruga replaces the one used from the departure point, which is taken in for maintenance.
