Electric railway journal . ation, and with the gradual displace-ment of steam power by water power, it is reasonable toexpect in the near future an activity in water-powerdevelopment hitherto unknown. November 5, 1921 Electric Railway Journal 825 Australian Railway Rail Standard Specifications for Railway Rails and FishplatesJust Issued—Rails Generally Are Higher for TheirWeights than Their American Equivalents THE Commonwealth Institute of Science andIndustry, Melbourne, Australia, has published thenew Australian standard specifications for railway railsand fishplates which were adopted this year and havebeen approved by the Interstate Conference of RailwayCommissioners. The specifications include ten draw-ings giving dimensions of the five standard section rails(T-rails) and fishplates. The rails weigh 60, 70, 80, 90and 100 lb. per yard. The section of the standard 80-lbrail and fishplates is reproduced. The rails generally are higher for their weights thantheir American equivalents in either A. S. C. E. or. Section of Australian Standard 80-Lb. Railway Railand Fishplates A. R. A. series. The heads are also wider and ofslightly less depth, while the sides of the webs arestraight in contrast to the curved sides of the webs inAmerican rails. It is of interest to note the largeradius of the fillet connecting the top and sides of thehead. It is greater than that found in most Americanrails. The greater head width is probably for the pur-pose of securing a larger fishing surface for the topsof the fishplates. A difference in fishing angles willalso be noted, particularly under the head, the slope ofwhich is 1:3. It is of interest to note the use of theterm fishplate in contrast to the American terms,angle-bar or splice-bar, and attention is called tothe use of the T-rail in contrast to the British bull-head or double-headed rail. In reference to the fishplate designs, it seems thatthese could have been designed along more progressivelines as they are quite similar
