 The SCR found that construction of its main line was more demanding, of time and of money, than it anticipated, and it allowed the Crieff branch to be put into abeyance.Crieff was the second largest town in Perthshire, and the branch line to Crieff had to be built.The SCR arranged for a nominally independent company, the Crieff Junction Railway (CJR) to be formed; it obtained its authorising Act of Parliament on 15 August 1853.
