The Barca d'Alva–La Fuente de San Esteban railway is a closed Iberian gauge line which connected the Barca d'Alva railway station on the Douro line in northeastern Portugal to the Spanish railway network. Passenger and cargo trains ran from Porto to Salamanca from its opening in 1887 until its closure on the Spanish side in 1985, with the Portuguese side also subsequently truncated to Pocinho three years later.[1]
