n any way either around the property of the railroadcompany at Highwood or the neighboring residence dis-trict, and is dissipated in the coldest weather without theformation of any ice on neighboring objects as might be up with their shafts in one line and are provided with mag-netic clutches for driving any desired one or more of thegenerators from either or both engines; this being proba-bly the first railway plant in this country completelyequipped with this system and its magnetic clutches, bymeans of which machines may be coupled or uncoupledwhile the apparatus is in motion. The general arrange-ment of the engines and generators is shown in the powerhouse plan, Fig. 4. There are three generators, one a 250-kw direct-current machine designed to supply that partof the line which can be reached economically with directcurrent from the power house. The other two machinesare 25-cycle three-phase alternators, each rated at the samepower as the direct-current machine, or 250 kw. As will

The alter-nator located outside of the large engine can be drivenfrom that engine alone, but either or both of the machinesbetween the two engines can be driven from either or bothOf the engines, working either independently or coupledtogether. The arrangement of the shafts and couplingsfor accomplishing this purpose is shown more clearly inthe section of that part of the shafting between the twoengines, reproduced in Fig. 6. In this drawing it will beseen that the rotating parts of the two generators aremounted, not on the solid shaft itself, but on hollow shafts together and thus join the dynamo quill to the
