In January 1838, Samuel F. B. Morse and Alfred Vail first demonstrated publicly crucial elements of their telegraph system, using instruments that Vail had constructed during the previous months.

In the early 1830s, the merchants of Bristol, long dissatisfied with their communication with London, began to wonder if the new railroad technology might be a solution to their problem. The Bristol Chamber of Commerce, the Merchant Adventurers and other local industrial bodies formed a committee in 1833 to discuss the ambitious proposal of laying a railway to London. Matters progressed swiftly. Money was advanced and the search for a first-class engineer to guide the effort.
