There was an engine shed at Broughton, which was demolished when the line was extended to Peebles, and the Neidpath Viaduct built between Lyne and Peebles still stands and is used as a footbridge over the River Tweed. The nearby Neidpath Tunnel was used as a refuge during World War II.
The "Tinto Express" operated services on the line to Edinburgh in competition with the "Peebles-shire Express"; as the journey was longer, the service was sold with an emphasis on comfort rather than speed. Services to Glasgow were faster than those of their competitors.
The Talla Railway was a reservoir construction line which briefly operated from Rachan Junction (near Broughton). The line was doubled from Broughton to there in 1895 in connection with this.
The North British Railway built a line connecting the new station to their existing station in Peebles (formerly the Peebles Railway). This connecting line was called the "Caledonian Branch".
The line from Peebles to Symington was closed to passengers on 6 June 1950, from Peebles West to Broughton closed on 7 June 1954, and the final closure (from Symington to Broughton) was on 4 April 1966. The section of the old line between Broughton and Biggar (starting beyond the coal yard in Broughton) is used as a footpath.
As of 2008, a feasibility study is to be undertaken to examine the possibility of reopening Symington station or building a new station in the vicinity, in order to provide the town of Biggar with a rapid public transport service to Glasgow.
