Liverpool Junction canal are among his works under this head. The improvement of the River Severn was carried out by him, and he made a series of reports on rivers. In 1841 he designed a new wharf on the Regent's Canal at Camden in London to allow transhipment of goods between the canal, road and railway. The Bute docks at Cardiff, the Middlesbrough docks and the coal drops on the Tees, and the Black Sluice drainage were undertakings which he successfully accomplished. Railway man After the introduction of railways Cubitt's evidence was sought in parliamentary contests. As engineer-in-chief he constructed the South Eastern Railway: he adopted the scheme of employing a monster charge of 18,000 lb. of gunpowder for blowing down the face of Round Down Cliff, between Folkestone and Dover (26 January 1843), and then constructing the line of railway along the beach, with a tunnel beneath the Shakespeare Cliff. On the Croydon Railway the atmospheric system was tried by him. On the Great Northern, to which Cubitt was the consulting engineer, he introduced the latest innovations. The Hanoverian government asked his advice on the subject of the harbour and docks at Harburg. The works for supplying Berlin with water were carried out under his direction; and he was surveyor for the Paris and Lyon railway. On the completion of the railway to Folkestone, and the establishment of a line of steamers to Boulogne, he superintended the improvement of the port there, and then became the consulting engineer to the Boulogne and Amiens railway. Among his last works were the two large landing-stages at Liverpool, and the bridge for carrying the London turnpike road across the River Medway at Rochester, Kent. Cubitt joined the Institution of Civil Engineers as a member in 1823, became a member of council in 1831, vice-president in 1836, and held the post of president in 1850 and 1851. While president in 1851 he had major responsibility for the erection of the Great Exhibition building in Hyde Park. At the expiration of his services he was knighted by the queen at Windsor Castle on 23 December 1851. He became a Fellow of the Royal Society on 1 April 1830, and was also a fellow of the Royal Irish Academy, and a member of other learned societies.
