TRACK AND OVERHEAD CONSTRUCTION. The roadbed inside the city limits consists of 90-lb. to the ends and sloped off. The dummy or space betweenthe tracks was also filled with stone to prevent accumu-lation of weeds, and to furnish a reserve for filling inany points where the earth in fills, etc., might settle. Where the road runs on the county highways, the con-struction consists of 64-lb. T rails 6 ins. high, supportedon cross ties similar to those already described. Brokenstone was placed under the ties to a depth of 4 ins., andwas brought up to within 3 ins. of the top of the rail. Finestone and stone dust were then filled in to the tops of therails, and sprinkled and rolled until thoroughly compactedby a steam roller. This forms an excellent driveway, therails offering but slight obstacle to the wheels of vehicles

FIG. 5.—VIEWS OF VIADUCT girder rails, supported on Georgia pine cross ties, measur-uring 6 ins. x 8 ins. x 8 feet. These are bedded on afoundation of gravel. As the street through which theroad passes had never been paved, the railroad companywas required to furnish new cobble or mosaic pavementbetween tracks and 2 ft. on each side. The general con-struction of the roadbed on macadamized and pavedstreets is shown in Figs. 6 and 7, and that on the com-panys own right of way in Fig. 10. The greater part of the remaining track was constructedof 60-lb. 4;j-in. T rails, with six-bolt splice bars, supportedon ties similar to those used for girder track. The ballastconsisted of 6 ins. of clean broken stone, 2.\ ins. ring, un-der the ties and filled level with the tops of the ties, carried turning in and out, ami the construction is much cheaperthan paved girder track. This style of construction hasbeen used to a considerable extent in the vicinity of Balti-more, and has been entirely sati
