Electric Rail Welding.—In the ElectricalWorld and Engineer recently appeared a descrip-tion of the electric rail welding plant of the LorainSteel Company, Ohio, as employed in making 7,500rail joints in the Buffalo street railway system. Thetrolley wire current is transformed by a rotary con-verter carried on the car into single-phase current of300 volts pressure, and then down to 5 or 7 volts byanother special transformer. The pressure being sogreatly reduced the current obtained is enormous,as much as 25,000 amperes being produced. Thejoint is made by means of fish-plates, welded on toeither side of the web under heavy pressure. Eachjoint takes fifteen minutes to complete.
