This means of conveying current tothe locomotive remained in use until lastMarch, at which time the overhead systemwas abandoned and the third rail systemsubstituted in its place. The third rail isplaced along the outside of the east andwest bound tracks. It is supported bymeans of a guard and insulator stand,which is attached to ties at centers of THE ELECTRICAL THIRD RAIL SYSTEM ON B. & 0. R. ELECTliM MdTciK IN MiUNT liUVAI. STATION. HALTIMciUK.

These guardand insulator stands form a support forplanks placed on either side of the rail,acting as a guard to prevent employescoming in contact with it. Through the two passenger and Mount Royal, which are abouta mile and one-half apart at the ends ofthe tunnel passing under the city, it wasnecessary to modify this construction insuch a way as to ]irevent all possibility of the traveling public coming in contact withthe charged conductor. To accomplish this,there were several precautions taken. Thethird rail was laid through the station atthe standard height and on the insulatorsin the regular way, but it was completelycovered over, the conducting shoe beingallowed to make contact through a woodencovered slot supported by iron membersfrom th
