The Pennsylvania steam railway between Rushville andConnersville makes a detour to the north to avoid the roughcountry, with the result that the electric route is aboutthree miles the shorter between the two towns. The Greensburg extension of the Shelbyville line passesthrough comparatively level country. The only noteworthy 672 STREET RAILWAY JOURNAL. [Vol. XXX. No. 15. structure on this line is a viaduct over the Flat Rock Rivernear St. Paul. The central portion of the steel structure iscarried by two concrete piers built up to a point about 20ft. below the track. The Connersville extension is built on a private right ofway 66 ft. wide. As in the construction of the portion ofthe line from Indianapolis to Rushville, the extension hasbeen built with a view of ultimately double tracking it. Forpractically the entire distances a roadway 28 ft. wide has. GLENWOOD SUB-STATION ON THE CONNERSVILLEEXTENSION been built. The cuts are 36 ft. wide at the bottom. Pro-vision is made for double tracks with 14-ft. track centersand center-pole trolley construction. The roadbed on both extensions is ballasted with 8 gravel under the ties, the ballast being obtained fromgravel banks along the line. The ties are of white or burroak placed two feet apart. The rails are 70 lbs. and arein 60-ft. lengths. They are laid broken. The maximum grades on the new extensions, and theseare on the Connersville line, are 3 per cent. Every advant-age was taken of the topography of the country to makethese velocity grades. There are no curves on them, withthe result that no braking of the cars is necessary, and thereis no loss of energy due to them. Vitrified clay pipe servedfor waterways up to 36 ins. in diameter, and cast-iron pipewas used for openings from 3 to 5 ft. in diameter. Thelarger waterways are of concrete constructio
