The Polmont line remains in use today by services to and from Edinburgh, but the Denny line was closed to passengers by the London and North Eastern Railway on 28 July 1930, with the Kilsyth branch following suit on 1 February 1935. Freight traffic to Denny and the power station at Bonnybridge continued until 1971. Passenger traffic to over the South Alloa line was withdrawn as a result of the Beeching Axe on 29 January 1968, though line as far as Throsk remained in use for M.O.D freight traffic until April 1978.
