Joints were placed oppo-site, making but one twin tie every 60 ft. Both re-sistance-type and motor-generator machines were usedin the welding. The electrical resistance of 3 ft. of railat the joints was equivalent to an average of less than 3ft. of unbroken rail, owing to the use of the cross-sectionof the joint plates and the International steel tie platefor conductivity. Flat joint plates, furnished by the In-dianapolis Switch & Frog Company, and plain angle barswith the lower leg planed to give welding space wereused on different parts of the work. No cross-bondingwas necessary as the rails are welded to the steel tiesat joints. From a summary of a few jobs on which costs arecompleted the following statement of the average costper foot
