Thisis in substantial agreement with British designs which havebeen in service for some years. There is every reason tobelieve that the average contours of both worn rails andworn wheels are so nearly alike upon different propertiesthat the committee should be able to settle upon a designwhich will approximate the average wear so closely that itmay be readily accepted, and we are inclined to the view thatthe form of contour substantially as above outlined should beselected.
