HEAVY SWITCHING LOCOMOTIVE. New York Central Lines. For hump yard service on the Lake Shore two ordinarylocomotives have been required to handle trains over thesummits in switching. To provide in a single engine the greattractive power required for this work the American Loco-motive Company has built, at the Brooks Works, a number of. the heaviest and most powerful switching locomotives everconstructed. Two of these are used in the hump yard at Elk-hart, two at Collinwood and one is used in pusher service onthe grade westbound out of Cleveland. The grades in the humpyards are from to per cent., and the grade out of Cleve-land is 39 ft. per mile. One of these locomotives is intendedto handle as heavy a train as can be hauled into the yardby the heaviest road engines. With a tractive effort of 55,300lbs., a total weight of 270,000 lbs., cylinders 24 x 28 ins. indiameter and a total heating surface of 4,625 sq. ft., theselocomotives take a high place among the largest in use. Allof the weight is upon the driving wheels, which are 52 diameter, and a very large boiler is required for supplyingsteam to these large cylinders when working full stroke. In
