Because of the connection being on the front axle it wasnecessary, in order to obtain a good length of main rod. to lo-cate the cylinders about 3 feet further ahead than usual in thistype of engine, the distance between the centre of the cylindersand that of the front driving axle being 11 feet. This permit=the use of an 84-inch main rod. Increasing the normal distance between the front drivers andthe cylinder center 3 feet involved, of course, an increase of alike amount in the length of the boiler; though, in this instance,this was accomplished with an increase of only 2 feet in thelength of the tubes. A very simple valve motion, involving no complications in. BALANCED SIMPLE ATLANTIC TYPE LOCOMOTIVE WITH SUPERHEATER—CHICAGO, ROCK ISLAND AND PACIFIC RY. a view to experiment after an experience by this company, ex-tending over four or five years, with balanced compound andsimple two-cylinder Atlantic type locomotives of practically thesame weight and power both with and without superheaters. As will be seen from the accompanying illustration, the en-gines present a very attractive appearance, the lines of the de-sign being symmetrical and pleasing. In working order they havea total weight of 202,000 pounds, of which 116,000 pounds iscarried on the driving wheels. This is an increase of 14,000pounds over the weight on driving wheels of the roads standarddesign of two-cylinder Atlantic type engine, this increase beingpermissible because of the balancing of the reciprocating partsand the elimination of the hammer blow. In the arrangement of cylinders, the design follows the VonBorries and Vauclain ba
