As the details may not be entirelyfamiliar to you, a brief review is given on page 604. This plantwill practically inaugurate the use of the heavy-duty type engine,in connection with single phase railway systems in America. The new engine equipment, now nearing completion, consists oftwo 500-hp Westinghouse double-acting engines of the horizontal.
