Dão line

The Dão line (Portuguese: Linha do Dão) was a metre gauge railway line in Portugal. It ran close to the Dão River (Rio Dão), between Santa Comba Dão and Viseu.

The line opened in 1890; it was closed to freight in 1972 and to passengers on 25 September 1988. The tracks have since been lifted and largely replaced by an "ecotrail" cycleway.
