Train Innovation Hub Power Supply

(Derby, June 2020) Porterbrook was converting a Class 319/4 unit into an Innovation Hub and showcasing it at the Rail Live exhibition at Long Marston in June 2019. As part of this exhibition, suppliers were invited to trial and demonstate new equipment on-board the vehicles. Porterbrook required a safe electrical distibution system to connect to their generator (650v) and allow 12 power points in the unit for the demonstrations (110dc and 230ac).
DB ESG was selected as the preferred supplier for this work.
