Theselocomotives were fully illustrated and described in this journalon page 365 of the September, 1907, and 164 of the May, 1908,issues. The service with them in the past has been eminentlysatisfactory in every way and up to a comparatively recent datethey had sufficient reserve power for all emergencies. The in-troduction of steel passenger cars and Pullmans, together withthe increased passenger traffic, however, has finally brought theweight of passenger trains to a point where it was desirable tohave a more powerful Ineomotive. and before mnkinj the last. manner indicate that the superheater increased the lioiler ca-pacity sufficiently to allow increasing the diameter of the cylin-ders to 23/, in. if the stroke was shortened to 26 in. The boil-er was thus redesigned and changed so as to give a distancebetween tube sheets of 21 ft. 6 in. instead of 20 ft., as has beenstandard, also for the application of the superheater tubes, butwas not altered in other respects. One of the illustrations shows a view of the front end withthe superheater and it will be noticed that a special design andarrangement of steam pipes has been employed. It was desired,of course, to obtain the maximum free area under the table platein the front end and therefore the steam pipes were broughtout through the shell at a point just below the center and car-ried into the top of the valve chamber. This arrangement notonly gives a freer and better design of front end, but also greatlyimproves the cylinder casting and gives the most direct pa
