Street. New York, March, 1924 No. 3 Southern Pacific Heavy 4-8-2 Type Locomotive Designed for Heavy Long Run Passenger Service Over Two Per Cent Grades In 1921 the Southern Pacific placed in service a numberof powerful 4-6-2 type locomotives which hauled 11 heavypassenger cars on a 1.5 per cent grade and established arecord for long locomotive runs. These locomotives havebeen regularly hauling passenger trains between Ogden,Utah, and Sparks, Nev., a distance of 536 miles, and haveaveraged better than 10,000 miles per month, fully meet-ing the expectations of the Southern Pacific in adopting which is made without changing locomotives, thus estab-lishing a new record for long locomotive runs. It is antici-pated that these locomotives will average about 12,000miles per month. The general design and specifications for these locomo-tives were worked up under the supervision of Mr.George McCormick, general superintendent motive power,and Frank E. Russell, assistant mechanical engineer; the

Heavy 4-8-2 Type Locomotive of the Southern Pacific—Built by American Locomotive Company a longer stroke for superheated passenger locomotives,thus keeping down cylinder clearances and obtaining amore economical steam consumption. The Southern Pacific has been the leader among therailroads of the country in developing the growing prac-tice of extending locomotive runs, and has just made an-other advance by placing in service ten 4-8-2 type locomo-tives to haul their heavy passenger trains between LosAngeles, Cal., and El Paso, Tex. These locomotiveswere especially designed for this long run over that diffi-cult mountain and desert territory, a distance of 815 miles, design l>eing completed and details worked out with theAmerican Locomotive Co., who built the locomotives.The outstanding characteristics sought in this design weremaximum tractive power within the weight limits, andample boiler capacity for the long-sustained runs. Thisrequired refinement in design throughout to prov
