The fan is placed withinthe cooler so that it will deliver hotair to the boiler fire and at the same - ■ w WW* . f MM tBhh > ^ _. .. - ■•»-■ * FIG. 2. SMALL TANK ENGINE FOR HAULAGE OF LIGHT TRAINS.

The small switchboardand the instruments required, thecontroller for grouping the four mo-tors in series, series-parallel andparallel, according to the drawbarpull to be exerted, and the regulatorfor controlling the voltage in theelectrical circuit, and, consequently,the speed of the train, are all placedon the drivers platform within easyreach. The foregoing comprises the mainand auxiliary machinery of this ex-perimental locomotive. The wholeis mounted upon a strong under-frame, which is carried upon twoeight-wheeled compound bogies, soconstructed that they will easilynegotiate curves. Each bogie car-ries two of the four driving motorsalreadv referred to. So far, the engine is purely expe-rimental, although it has been testedto some extent on certain Scottishrailways; but the design presentsstrong possibilitie
