The central portion of the pit, however,will be entirely open with the exception of sufficient plat-form to enable those taking part in the tests to secureindicator cards, make observations of temperatures andobtain other information of this character. A traveling electric crane E of 10 tons capacity, andhaving a span of 43 feet between centers or runwaysF, serves the entire space occupied by the testing plant,also sufficient space beyond the pilot of the longest loco-motive to be tested, to reach the cars loaded with suppliesfor the plant. The crane will be used for handling thesupporting wheels, axles, brakes, pedestals and otherparts, when necessary to change their setting and, further,for handling all of the coal used during the tests. The water required for locomotives under test will be. Locomotive Testing Plant at the Louisiana secure as nearly as possible constant speed, there is a by-pass around the main valve controlling the supply ofwater for all the brakes, and in this by-pass is an auto-matic valve controlled by the speed of the the speed increases beyond the desired number of revo-lutions per minute, the by-pass valve opens, so as toincrease the pressure on the brakes, and if, on the otherhand, the speed of the locomotive falls below that desired,the automatic valve closes, and decreases the pressure onthe brakes. The supporting wheels resemble in form, the usuallocomotive driving wheels, having cast steel centers withtires shrunk on, and held in addition by retaining rings. The contour of the tire is approximately that of thehead of a rail, but provided with means of keeping awayfrom its bearing surface the oil. which will necessarilydrip from the locomotive while running.
