Construction began in 1825 with George Stephenson as the engineer, with the assistance of John Dixon as resident engineer and Joseph Locke in charge of track. In 1827, following the boring of Tyler Hill Tunnel, work stopped through a lack of funds. Robert Stephenson took charge. Money was raised to enable the completion of the line. Dixon left the company, being replaced by Joshua Richardson. The promoters returned to Parliament three more times to obtain authorisation for the raising of additional funds. The construction of Whitstable Harbour, under the direction of Thomas Telford, was completed in 1832.
