Even the largeelectric locomotive, however, is not entirely untried, andwhatever doubts steam engineers may have as to theirability to do the steam engines work, there is no doubtin the mind of the electrical engineers acquainted withrailway work. In our January, 1895, issue, we gave the details of the for the overhead work. But in this case electric tractionhad to be adapted to the traffic instead of adapting thetraffic to electric traction as is generally found best. Thetunnel is only a link in a through line and long trainsmust be hauled in their entirety, hence the necessity forheavy locomotives. These locomotives take from 500 to3,000 amperes of current when in service or about tentimes as much as any electric motors now taking currentfrom trolley wires. This is also far beyond the carrying <^0jwdfj{aJA\^\f^^^ 489 •/.■,^^///////W////y,^^//A. capacity of any solid wire made. The conductor selectedtherefore was a trough formed by two 3-inch iron Z barsin which the shuttle-like brass trolley shoe slides. TheseZ bars are if, inches thick riveted to a cover plate J^inch thick and 11^2 inches wide. The trough is made in sections 30 feet long and weighs 90 pounds per method of suspension of this trough is made plain inthe engravings. Lattice steel poles on each side of theroad carry between them transverse trusses. Fromthese trusses which are 150 feet apart are stretched
