Although the wayside energy storage alone can effectively recover the regenerative braking energy, energy consumption on the traction network cannot be avoided, so it is difficult to reduce the probability of regeneration failure; Although a separate on-board energy storage system can directly absorb regenerative braking energy when the train

SEPTA rolls on with wayside energy storage systems (WESS)

Wayside energy storage systems (WESS) capture energy from braking trains, but instead of releas - ing it as heat they store it for later use. In SEPTA''s case, this was accomplished using a lithium-ion battery combined with ABB converters. How much energy the system can capture from any one train depends on a variety of factors (see boxed text).
