Powering trams (part two)

Using onboard energy storage we can considerably increase energy recovery through regeneration, and also reduce line current, enabling much lighter overhead line equipment and feeders with fewer and smaller substations to be possible. This will also enable some degree of off-wire running, which could be of benefit in depots or for short stretches …
