 The thinly populated area brought little traffic to the railway and tourist traffic declined also in the middle decades of the twentieth century.The rise of motor buses accelerated the loss of passenger business, and on 1 October 1951 the line closed between Balquhidder and Comrie.However the track remained in situ until 1959 as the line was used sporadically throughout the 1950s to transport materials to the Glen Lednock hydro-electric schemes under construction in the area.
