This locomotiveis the lightest in proportion to maximum horsepower capacity,of cinv locomotive of this type which has yet been built andthe design is the result of an unusually painstaking studyboth by the railroad staflf and by the builders. The locomotive has a total weight of 345,000 lb. of which230,000 lb. is on the drivers. It has a maximum tractiveeffort of 54,800 lb., and, using Coles ratios as a basis ofcomparison, has a maximum horsepower capacity of 3,030. 1000 900 800 Miles from Counc 700 WO1 Bluffs i 1 Max.

Eastbound the sched-ules call for average speeds of from to miles anhour between Evanston and Green River, to milesan hour from Green River to Rawlins and 35 to 37 milesan hour from Rawlins to Laramie. Few stops are called foron any of the overland trains except at division points. To maintain these schedules widi Mikado t\-pe locomo-tives it has been necessary to resort to high running speedson the down grades to make up for the comparatively lowspeeds on the heavy up-hill pulls. This has had a marked ef-fect in increasing track maintenance and to some extent thecost of locomotive maintenance. The Mountain t\pe locomo-tive with its high sustained capacit\- is expected to bring themaximum and minimum operating speeds
