The Upsala -Lenna Jernväg (Lennakatten)is a 33 km museum line that runs regular steam and railmotor services north-east from Uppsala throughout the summer. It is part of the once extensive 810mm gauge network that once ran north-east from Stockholm. A summary of the complex history of these lines can be found on the preservation society's web site, available in English and German as well as Swedish:

Another part of this network still exists as part of the Stockholm region commuter network, see separate subcategory on this web page.
