Upsala-Lenna Jernväg, known as Lennakatten, will celebrate 150 years with extra trains and jubilee programs on 27–28 June.
The railway opened in 1876 between Uppsala and Länna to transport iron. It quickly became popular for pleasure trips among residents of Uppsala.
The museum association Museiföreningen Stockholm-Roslagens Järnvägar took over operations in 1974. Uppsala kommun purchased the line to Faringe in 1978. Today around 250 volunteers run the railway.
During the anniversary weekend trains will run nonstop throughout the weekend and all night. Special program points are planned along the entire line.
