Not illustrated. 1918 edition. Excerpt: of the drums was used as a reheater. By setting back the front tube sheet in the boiler and making longer drums a higher degree of superheat was obtainable. In 1911 the Locomotive Superheater Company applied a "Schmidt" type firetube superheater to a Chicago & Northwestern engine. This had a cross header, the superheater tubes coming from the bottom of this and being bent to the horizontal to go into the fire tubes. This superheater should be interesting because the greater part of the superheaters applied today in the United States are practically of this design. At about this time other variations of the smoke tube superheater were introduced in both France and Germany. In this country the use of superheated steam on locomotives began to grow rapidly and by 1912 there were about 2500 superheater locomotives in the United States and Canada, largely of the fire tube type. Switch engines also began to be equipped. By the following year practically all of the engines under construction had superheaters and nearly all of them were of the smoke tube design. It was in 1912 that the Southern Pacific first used the smoke tube superheater. ' In 1916 there were over 16,000 superheater locomotives in service in the United States and this number has greatly increased since then--I have not the figures as to just how much. At present I suppose it is safe to say no locomotives are being built in the United States without superheaters, and that all are of the "Schmidt" smoke tube type. The superheater has justified itself and is recognized as a necessary part of the locomotive. Many roads have been converting saturated to superheated locomotives, and the Federal Railroad Administration has inaugurated a regular plan more
