Description

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Conduit current collection is a system of electric current collection used by electric trams, where the power supply is carried in a channel under the roadway, rather than located overhead. The power rails for conduit cars are contained in a vault between and underneath the running rails, much in the same fashion as the cable for cable cars. The vault contains two "T" section steel power rails of opposite polarity facing each other, about 12 inches apart and about 18 inches below the street surface. Power reached the car by means of an attachment, called a plough, that rode in the conduit beneath the car. The plough had two metal shoes that pushed sideways against the power rails and connected to the car's controller and motor. The running rails are not part of the electrical circuit. In the United States, the cars were sometimes popularly but incorrectly called trolleys but did not typically draw power through a trolley pole from an overhead wire as trolley cars do.show more
