Miranda do Douro
The line ran from Pocinho station, which was a junction with the main Douro railway line through the Douro Valley to Oporto. The northern terminus of the line was at Duas Igrejas, a tiny settlement several kilometres from the municipal capital of Miranda do Douro. The line opened from Pocinho to Carviçais in 1917, with extensions to Lagoaça in 1927, Mogadouro in 1930 and eventually reaching Duas Igrejas in 1938. The line was never completed as far as Miranda do Douro. Much of the route was located within a few kilometres of the border with Spain.
