The acconipanymg diagram shows the ratio between thecentrifugal force and weight for speeds up to 125 miles per hourand radii of curves up to 13, 000 ft., and shows clearly the advantagewhich the suspended niono-rail system has in this respect over theordinary two-rail system. The lines of the road can follow ex-actly the lines of the streets, and the corners can be turned without.

Also it must befurther taken into consideration that the width of the elevatedstructure for a suspended railroad is only equal to the distance be-tween the center line of the tracks, whereas, in the case of the it is evident that the Langen system darkens the streets much lessthan the usual elevated structures. In case of a car running on two tracks there is always somenoise resulting from shocks produced by the inequality in theparallelism of the rails; as the Langen railway only employs onerail the noise is greatly reduced on account of lack of resonancepf the structure, as the road bed of the common elevated railwayforms a compact structure, whereas in the Langen system it con-sists mainly of two beams. Furthermore, the suspended car can bebuilt much lighter than an ordinary car on account of the fact thatthe vertical parts of the car withs
