To quantify the efficiency of energy recovery, one can use the value of energy Wp, obtained for this area, and an indicator of its efficiency (2) a = g W p W Π = W p N + M Δ h, which represents the acceleration useful in the recovery process and measured in Kp =a/g kWh/ (t.m) or m/s 2. Relation is the efficiency of energy recovery.

ABSTRACT. Wayside Energy Storage Systems (WESS) introduce savings in the costs of the electric energy supplied to the railway catenary, by reducing the peak load and also the total energy demand (if locomotive regeneration is available). A number of energy storage systems are evaluated and two are shown to be practicable: • Lead-Acid
