The work hasbeen under the charge of W. C. Gotshall, the well-known electric railway expert, formerly of Chicago. Tohim is due the credit of working out the technical detailsand pushing to success a plan which met with muchopposition on the part of local experts. He has provedthe soundness of his judgment in advocating the OVERHEAD CROSSINGS, THREE-WIRE SYSTEM, ST. LOUIS. John ScuUin, president, and Harry Scullin, general man-ager of the Union Depot Railroad also deserve the thanksof the other street railway men ot the country for givingthe sjstem a trial in spite of the assurances theyreceived from certain electricians that it would burn outthe entire station and bankrupt the company. The portion of the road selected on which to try theexperiment was the down town loop comprising fivemiles of single track. This is the part on which there isthe heaviest traffic and on account of its many curvesand crossings is the most difficult to successfully operateon the three-wire plan. It was admitted beforehand thatif the loop could be operated in this way there would beno difficulty on the rest of the system. Another reasonfor making the change on this part of the road was thatthere was a heavy drop in voltage on that portion. Figure 2 shows the lines now operated on the three-wire p
