Above and be-low that particular point the cars can-not possibly meet. Here there is aswitch and the line widens out into twotracks with four rails; this slight devia-tion in the track does not effect the lineof pull of the cable to any noticeable ex-tent. It is. of course, only at theswitch that the four rails are flanges of the wheels run on theouter side of the rails, and the frog lieson the center line at the point, where itbranches out into the two rails requiredat the switch. This arrangement has theeffect of making the outer rail, for eachcar. continuous all the way. and witliflange of wheel on outer side, it is thecontinuous rail which deflects the caraway from the center line of pull at the.

In theupper halt of this incline the grade is^7 ft. in 100 ft., and the top of LookoutMountain is 1,700 ft. above the city,and from the top a fine view may be arrangement of the wooden guardstringers is interesting. If a derailed■car was going down and got off towardthe left side of the illustration it couldonly proceed out of line until the wheelsTjelonging to the middle rail caught theleft stringer, and though the car mighttip over at a considerable angle, it wouldprobably be held by the cable. If it gotoff the track so as to move toward theright side of the illustration the guardstringer would at once engage the outer■wheels and prevent the car from movingover and cutting or fouling the cable ofthe car be
