Thismethod of reinforcing poles has been found to add very largely totheir strength and it also adds a number of years to their life. The standard span wire is a .galvanized -strand steel cable in-sulated from the steel poles at its ends by giant strain insulators.,-\ No. 00 hard drawn trolley wire suspended from soldered earsinsulated by round top bells is used. The overhead construction is maintained by the crews of sixemergency wagons and two repair wagons. During the summer anadditional emergency wagon is used. The emergency wagons are onduty 24 hours every day in the year and extra wagons are avail-. SETTING WllH luUKK , able in case of fires or other unusual occurrences. The type ulwagon used for emergency work may be seen in one of the illus-trations. These w-agons arc built in the shops of the company anddesigned to suit its special needs. The wagon consists of a strongrunning gear and box upon which is a telescopic tower of steelangles. By means of a crank and chains the upper portion of thistower may be raised so that its platform is at the proper heightfor working on any portion of the trolley wire. The extension platform is mounted on a circle which allows it to be swuukthrough jGo degrees. This feature permits of the working uptm atrolley wire with but little trouble to cars operating on the track, aswill be seen from the illustration. Besides the materials for theusual line troubles these wagons carry tools f<ir <|uick repairs tocars and trucks. Jacks arc also carried lo aid in replacing dcraileilcars, A view of the interior
