The positive andnegative feeders will necessarily be used in diverging di-rections to avoid the possibility of short circuit. The feed-ers are also provided with double-pole switches, so they.

For night load the company has a Russelltandem compound engine, directly connectedwith a 350-kw. General Electric generator. On the south side of the station is a switchboard, whichfor a number of reasons possesses unusual interest. Oneof these is that it has the largest three-wire street railwaypanel switchboard in the world. While the company hasnot yet commenced the operation of its lines on the three-wire system, and has no immediate plans for changing tothis system at any stated date, the advantages of thatmethod of operation were considered so great as to war-rant the installation of the necessary apparatus on the can be connected to either the positive or the negative busbars, which will facilitate the balancing of the two sides ofthe three-wire system. The construction of the switchboard is the standardWestinghouse No. 5 type, the slabs being
