REALIZATION OF GRAVITY DRIVE IN METROPOLITAN RAILWAYS FOR LOW LOSS RECUPERATION OF KINETIC ENERGY OF VEHICLES WITHOUT LINEAR INDUCTION MOTOR
One of the advantages of the Cyclo Train gravity drive with a great slope lies in the possibility of a very flexible position of the line in the vertical plane and, additionally, in a high transport velocity (e.g., 32 km/h at 512 m distance between stops). The disadvantage lies in the large tunnel depth and in the necessity of applying the linear induction motor with variable frequency, synchronous and asynchronous, respectively. If the maximum slope is limited to 100 exp 0 /oo, it is possible to omit the linear induction motor and make the drive interact by friction between the wheel and the rail. If the distance between stops is increased from 512 m to 662 m, the mean transportation velocity of 32 km/h can be maintained. The maximum tunnel depth is reduced from 38 m to 21 m with stations provided in open hollows of 120 m length, inclusive of the open slopes, and with 2.5 m deep platforms to save space for traffic on the zero level. The maximum transportation rate is 12,000 persons per hour in one direction for platforms of 64 m length, 2.20 m width of the vehicles, and a sequence time of 90 s. If the platforms, arranged sidewards of the tracks, have a width of 2.5 m, a total width of 10.0 m is needed for a station. This value would increase to 14 m for full profile trains.
