. A report on the alternating current, single phase, interurban railway line between Bloomington and Peoria . ich will he given later. The sections of thetrolley operating on the different currents are separated bydead sections in the trolley which consists of a section ofthe regular 000 wire placed between two section unsulatorsmounted on adjacent poles, which gives a dead section of 140feet. The type of section insulator is illustrated in the terminals operate on the direct current and the pointsof change from the alternating to the direct current are atthe connection of the Peoria and Pekin Union tracks, in EastPeoria, about one half mile from the river, at the west end;and the other just west of the under crossing of the LakeErie and Western at Bloomington; that is, about one mile fromtVie terminal. The high tension line is carried on the same polesand consists of three #2 hard drawn copper wires which carryvoltage of 33,000 volts. Ho,312 Locke insulators are used,cemented to truss pins and fastened to a cross arm 5-3/4 x3-3/4 x 10», which is fastened to the pole with 3/4 x 13. Figure 5 Telephone Booth -8- inachine bolts. Angle iron cross arm braces are used to keep thearm in line. As the high tension line extends over the entireIllinois Traction System, power may he carried from any of thepower houses to any of the sub-stations at which it may he Peoria Power House normally supplies the power for the Peoria -Bloomingtoiij Bloomingt on-Decatur and Mackinaw-Lincoln Divisionsand the Peoria City lines, a total of 110 miles of track,exclusive of the city tracks. This pole line carries the companys telephone wires,which also extend over the whole system and may he used for com-mercial purposes in connection with their business, hut it isintended primarily for the transmission of train orders. The line consists of a pair of #10 hard drawn copper wires mounted -To on Locke insulator, of the same makef ^ avoid the induct-ance effectsj The cr
