The period of 1844–45 proved to be especially busy with new lines from Birmingham to Wolverhampton, Shrewsbury, Newton, and Chester,; the Yarmouth Junction, from Diss and Beccles, the Irish Great Western, from Naas, by Tullamore, to Galway, the Metropolitan Counties Junction, from Gravesend, by Reigate, Dorking, Weybridge, Staines, Rickmansworth, St. Albans, Chelmsford, and Billericay to Tilbury, the London, Hammersmith, Staines, and Windsor, 25 miles, and several smaller lines. The Southampton and Dorchester Railway in 1847 was notable as "Castleman' Corkscrew": its promoters insisted that it should serve as many of the local communities as possible. At this time, Moorsom surveyed the line from Exeter and Plymouth to Falmouth, the West Cornwall Railway, from Truro to Penzance.
