Railway and locomotive engineering : a practical journal of railway motive power and rolling stock . ••K-2 omy in fuel consumption has called intoaction the brightest minds in the electricalengineering world to produce the requiredilluminating power at the least possibleexpense. Hence those who may be fa-miliar with the details of the earlier prod-ucts should take the opportunity to famil-iarize themselves with the improvedelectric headlights that are now beingplaced in service to the end that the bestpossible results that a proper installationand maintenance of the appliance maybe obtained. The Pyle-National Type •K-2 andTurbo-Generators and Headlights em-body the most recent developments in thedesign and construction of electric incan-descent headlights for steam locomo-tives. The equipments are suitable bothfor switching locomotives and forlocomotives in road service on whichan incandescent headlight is capacity of the K-2 turbo-. •K. is 50O watts, and the normalcapacity of the K 350 watts, which isnot only ample to illuminate the headlightand cab, but also the classihcation, num-ber indicator, deck and marker speed and the voltage control are comliine<l in a positive regulating mechan-ism of the centrifugal type, which alsocompensates for variation in boiler pres-sure between 125 and 250 lbs., saturated orsuperheated steam. .Xn important andeconomic feature of the regulating mech-anism is to conserve steam. In yards andstations where the full capacity of theturbo-generator is not required, whereliossibly the cab lights only are necessary,or where the total requirement is belowthe capacity, as in switching sufficient steam to perform the actualwork is admitted to the turbine nozzle. The steam is conveyed to the turbine1 y a ^-in. pipe. A strainer, easilycleaned, effectively prevents scale or dirtfrom obstructing the nozzle. ExhaustMcam is disposed of through a I
