The story
In 1879, tracks for a horse-drawn railway line were laid for the construction of a new lighthouse. The tracks were converted for locomotive-hauled trains about 10 years later, and the line opened in 1888 as a successor of the horsedrawn line. The network reached its peak length in 1938, with a track length of about 45 km (28 mi). The line celebrated its 125th anniversary on June 15, 2013.
