The climax of this was in 1845, the year in which the Caledonian Railway obtained its Act of Parliament, authorising the creation of capital of £1.5 million to build a railway from Edinburgh and Glasgow to Carlisle. Other Scottish trunk railways were authorised in the same year, and this encouraged the promotion of increasingly wild schemes intended to be submitted to Parliament in the following session. The West Highlands of Scotland were not omitted from the schemes proposed. Prospectuses were issued for the Scottish Western Railway and the Scottish North Western Railway, as well as the Scottish Grand Junction Railway and others. Some of the prospectuses told of abundant income and easy construction through imaginary gently rolling land. One line at least admitted the mountainous character of the area but proposed the use of the atmospheric system to overcome the difficulty.
