200 ENGINEERING WONDERS OF THE WORLD. COLONIAL LOCOMOTIVES. In Canada the railways and locomotives are essentially American, so that Canadian loco- motives are relegated to the American section. On the other hand, so many of the South American railways are operated by British- built engines that they may be considered here. In India, parts of Australia, and in South America, many tracks have a gauge of 5 feet 6 inches, instead of the normal standard of 4 feet 8J inches, and the duties are suffi- ciently severe to call for very powerful loco- motives, which are easily provided, thanks to the large dimensions available. We should note, however, that even on the narrow gauges of Africa and of the countries named above very large engines are used. Most Colonial locomotives are designed and built in Great Britain. Fig. 14.—FOUR-COUPLED BOGIE EXPRESS LOCOMOTIVE, MADRAS RAILWAY.’ Cylinders, 18| inches by 26 inches. Driving wheels, 6 feet 2 inches. Heating surface, 1,357 square feet. Working pressure, 180 lbs. An interesting example of an ordinary four-coupled bogie engine, built by the Vulcan Foundry Company, Limited, for the Madras Railway. The design is essentially British, the only peculiarity being the use of the sun blinds on engine and tender, the latter of which is also provided with a cab to shelter the enginemen from the sun in the hot districts. Fig. 15.—SIX-COUPLED EXPRESS LOCOMOTIVE USED ON INDIAN RAILWAYS. Cylinders, 19 inches by 26 inches. Driving wheels, 6 feet 2 inches. Heating surface, 2,020 square feet. Working pressure 180 lbs. Designed by Messrs. Rendel and Robertson, and built by the North British Locomotive Company, Glasgow. It will be noticed that the Walschaert valve gear is employed.
