Paper by Philip W. Davis, Engineer I have always found the street railway man of an inquiring turnof mind. Necessity has made him careful, and he does not always. .Miles a 5f. j c 8 10 , 12 Strc-et Ry .Journal confine himself to the question, does it pay? he is interested inknowing why. It is this side of the question that Mr. Stone hasbidden me pursue, and I will try to do it without being unpleas-antly technical, but I trust you will excuse me if I introduce a fewfigures. With a view of avoiding the want of exactness which usuallyaccompanies a general statement, I have figured out the solutionof a railway transmission problem by three different methods andhave presented it in a graphical form so that the results may beeasily compared. While this problem is a special case of a linebattery, still I think it illustrates fairly well the value of a storagebattery in all its phases. The diagrams represent at the bottom asingle track with turnouts, marked by loops, 2 miles apart. It issupposed that 8 miles from the power station is a rather long andsteep grade, reaching perhaps as high as 8 per cent. The track is
