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).
