Twin screw, turbine geared, cross-channel train ferry steamer, Twickenham Ferry, on trials June 18, 1934. Built by Swan, Hunter & Wigham Richardson Ltd. for Southern Railway, England, for service between Dover and Dunkerque CROSS CHANNEL FERRIES Twin Screw, Geared Turbines, Coal Burning N IMPORTANT project for A“ improvement of transpor- tation across the English chan- nel, between Dover, England, and Dunkerque, France, is nearing reali- zation in the completion and success- ful trials on June 18 of the steamer TWICKENHAM Ferry, first of three especially designed vessels under con- struction at the Neptune yard, Walker, Newcastle-on-Tyne, of Swan Hunter & Wigham Richardson Co. Ltd., for the Southern Railway. The second vessel, named Hampron Frrry, was launched on July 30 while the third vessel the SHEPPERTON Ferry is on the stocks. In order to perfect the efficiency of this service, locks are being con- structed at both ports which will en- able the vessel to link up with the shores on level terms at any state of the tide which has a range of about 20 feet. The new vessels combine all the advantages of the most modern cross channel boats and the conveni- ences of an ocean liner, with high class accommodations and promen- ade decks. Railroad Cars and Automobiles Each vessel is capable of carrying a train of 12 sleeping cars, or alterna- tively 40 loaded freight cars. In addi- tion, a special garage is provided on the after end of the upper deck for the accommodation of 25 automobiles. Cars can be driven directly on the ship by an inclined ramp. During the voyage motorists are at liberty to use the passenger deck accommo- dations and on arrival at destination can drive their cars off the vessel. 12 Additional parking space for auto- mobiles is available at the after end of the train deck, where the surface between the rails is raised for this purpose. About 25 automobiles or heavy motor driven vehicles can be accommodated in this space after the railroad sleeping cars or freight cars have been secured in place on board. The new service will make it pos- sible for a sleeping car express to leave Victoria station, London, at midnight and arrive at Paris the next morning in time for breakfast without passengers leaving their berths unless they desire to do so tc enjoy the luxuries of a first class Principal Characteristics NAG eres ne one a seu wes Twickenham’ Ferry Builder.Swan, Hunter & Wigham Richardson Ltd.

This represents a marked advance in rapid and comfortable transit and the service to Paris can easily be ex- tended to more remote places on the Continent. It is also easy to visual- ize the inauguration based on this service, of a wide range of short ex- cursions to the Continent from prac- tically all parts of England. Both the design and the building of the TWICKENHAM Ferry and her two sister vessels have been carried out under the general direction of Sir Westcott Abell, professor of naval architecture at Armstrong college, Neweastle-on-Tyne, who has been re- tained by the Southern Railway com- pany as its expert advisor. In the de- sign of these vessels, representatives ot the owner wisely decided to take full advantage of all the modern facilities and high individual talent in naval architecture and marine en- gineering for which Great Britain is justly famous the world over. Utmost Care in Planning No vessels of comparable size and importance were ever, it may be said, more carefully planned. Model ex- periments of both hull and propell- ers, aS reported in a preliminary ar- ticle on these vessels, published in the July issue of Marine REVIEW, were carried out with the utmost care and under the most skillful supervi- sion, to an extent hardly ever before realized. These model experiments were conducted at the National Phys- ical laboratory at Teddington under the direct supervision of G. S. Baker.
