The Talla Railway was a privately constructed railway line in southern Scotland. It was built 1895-97 to aid the construction of the Talla Reservoir, to serve the water demand of Edinburgh. The railway was about eight miles (13 km) long, running south from a connection with the Caledonian Railway's Peebles branch at Broughton. A private passenger service was operated for workmen on the reservoir construction. The reservoir was inaugurated in 1905 and the railway was lifted by 1912.
