Notes:  After the collapse of the "Railway Mania" bubble, a more cautious approach set in, with only well-researched projects, particularly those supported by the larger railway groupings, able to attract funding. In this period what became the London, Chatham & Dover Railway (LCDR) struggled to emerge, extending from Chatham to London and as far as Canterbury in the other direction. Meanwhile the LSWR reached Exeter, in competition with the GWR; a railway line ran the entire length of Cornwall; and the GWR reached Nayland in Pembrokeshire, from where Brunel dreamed of capturing the transatlantic traffic. The Midland Railway now had its own main line as far south as Bedford with a continuation to Hitchin and another unsatisfactory connection, this time with the GNR, who now had a direct route on from Peterborough to Doncaster. In Scotland, Inverness was connected to the rail network via Aberdeen.
