Electric Locomotive built by Messrs. Schneider and Co. Tenbrink heating tube. The cylindrical body of the boiler is of the oval section shown on the cross section and on Plate CLXXV. Provision is made for the admission of steam to the cylinders, when working with closed regulator valve. A cab is fitted in the rear for the firemen, and a second in front for the driver. The engine carries a Laval dynamo turbine for lighting the train. The boiler-plates, rivets, tie-bars, angle bars, connecting- rods and cranks, are of nickel steel. The large wheels are of cast steel. The tender illustrated on Plate CLXXIV., is carried on two trucks ; the following are some particulars : Diameter of wheels 1.060 ni. 3 ft. 5J in Total wheelbase 7.800 m. 25 ft. 7 in. Weight empty ... 24,000 kg. 24 tons ,, in working Order ... 1 59,000 kg. 59 tons The tender contains 28 cubic metres (989 cubic feet) of water and 7 tons of coal. The breaking strain of the nickel steel for boiler-plates, rivets, &c., averages 50 to 55 kilogrammes (31.75 to 34.92 tons per square inch) ; that of the connecting-rods and cranks 60 to 65 kilogrammes (38.00 to 41.27 tons per square in.). The driver communicates with the firemen through a speaking-tube and by ringing signals. ELECTRIC LOCOMOTIVE. The electric locomotive (Fig. 1095) built by Messrs. Schneider and Co., and exhibited in their pavillon, was designed with a view to carry out complété traction tests with heavy trains at a high speed, on the works track from Creusot to Montchanin, with a third rail for taking the current and return to o-round. It consists of a frame, with
