Discussion on “2400-volt railway electrification” (Hobart) and “trunk line electrification” (Kahler). New York, May 20, 1913. (see proceedings for May, 1913)

A. H. Armstrong: The two papers presented before the Institute at this meeting arrived at the same happy conclusion as to the benefits to be secured in the electrification of steam roads, but differ as to the means of securing this end. In other words, one paper advocates the single-phase and the other the direct-current motor. Instead, therefore, of following the usual procedure of side-stepping the question of single-phase versus d-c., I will confine my remarks to a broad discussion of this question as affecting the general subject of electrification.
