About 70 or 80 percent of the traction energy employed in the operation of metropolitan and suburban railways on lines with the stops arranged at short intervals are used for the kinetic energy of the vehicles. If at all, this energy is recuperated only at a rate of approximately 30 percent. Gravity traction allows the kinetic energy of the vehicles to be recuperated at a rate of about 90 percent during deceleration, which would decrease the overall energy input by 63 to 72 percent. However, this requires the line to be arranged uphill and downhill, and a traction system not based on the interaction of forces between a wheel and a rail might be needed. The result would be high average speeds, without requiring more traction power. A relationship is established between the parameters of the trackway and the change of the vertical and horizontal acceleration values as a function of time. (Author)
