In this country the steam turbine is now operating in severalplants. The first prominent installation was at the WestinghouseAir Brake Companys works, at Wilmerding, Pa., where the firstunit was started in August, 1899, two more shortly after, and thefourth unit in April, 1901. Thus the plant has been in service, forthe most part, more than three years, and the fourth unit abouteighteen months. The plant operates regularly eleven hours aday, the service being electric power and lighting. With the ironfoundry running at night, one turbine is run twenty-two to twenty-three hours per day. In general, the units have run quite to their. FIG. I.—LONGITUDINAL SECTION OF WESTINGHOUSE TURBINE ultimate promise, or whether it has been well tried and its advan-tages proved. What has it accomplished? What justifies its use?What otherwise unattainable results will it produce? What are itslimitations? It is this aspect of the case on which the light isneeded. It is of little moment what the direct or contingent advantagesof the turbine may be, if its reliability remain in doubt. Offered,as it is, in large units, and being apparently more related to theclasses of service which impose the most exacting requirements,the demand is imperative that in this one vital respect there belittle left to chance. Before recurring to actual experience it may be instructive toconsider for a moment the general character of the turbine as atype of motor, contrasted with the piston engine.
