b) What the status is regarding the Electric New Routemaster (LT11) currently being trialed with Metroline and when it will re-enter into testing, and if TfL is considering implementing/is aware of Wrightbus' NewPower repower option to further extend their lifespan in London: https://wrightbus.com/en-gb/new-power
There is an existing trial of a converted electric NRM, which was developed by Equipmake. Ahead of the trial, Equipmake had developed a potential design that would allow the NRMs to be converted and approached TfL to see if it would be possible to trial it in practice at no cost to TfL. Since the trial initially began, there have been technological advancements and battery improvements, so Equipmake have evolved the converted model to incorporate these ahead of further testing. LT11 is expected to re-enter into service for testing over the next few months.
Currently, TfL is not exploring the Wrightbus repower for the NRM buses.
