of a sheet iron cab containing the controller,instruments, air-brake, sand boxes, etc., and mounted on alocomotive truck. There are to be four G. E. 56 motorsone to each axle, giving a total drawbar pull of 14,000 lbs.The locomotives are to weigh 35 long tons and each trainis to consist of seven cars seating 336 persons and weighingloaded, 105 long tons. It is estimated that the road willcarry 43,000,000 passengers per annum at an average fareof four cents. The generating station is to be located at Shepards Bush.Six 1,300-h. p. Allis engines, each direct connected to anS5o-k. w. G. E. dynamo, constitute the power station equip-ment. The dynamos run at 94 r. p. m. with a frequency of25 and initial voltage of 5,000. There are to be four sub-stations equipped with step-down transformers and rotaryconverters. The line voltage is to be 500. The elevators, of which there are to be 49 will be of thedouble drum type and run at a speed of 150 ft. per minute.The capacity of each is 15,000 lbs.

MAP SHOWING ROUTE OF THE CENTRAL LONDON RAILWAY. laid in separate tunnels of 115^ ft. internal diameter exceptat the stations where they are widened to 3i ft. for a dis-tance of 375 ft. At each station are four vertical shafts, two23 ft. in diameter and S7 ft. deep and two iS ft. in diameterand 76 ft. deep; the larger contain two entrance and twoexit elevators and the smaller ones spiral stairways. Theroute and location of the 14 stations are shown on the map.The rails weigh 100 lbs. per yard and are laid on cross-ties. The third rail system of contact will be used, and theline sectioned and the feeder system controlled by signalboxes. In order to retard and accelerate the trains moreeasily at stops there is a 3 per cent grade on each side ofeach station ; it is estimated that by this plan a saving ofone-third of the power otherwise necessary for the acceler-ation of the trains will be made. The schedule speed willbe 1414 miles per hour with stops of 20 seconds. X-RAYS AND DAMAGE SUIT
