57301 Goliath (leased from DRS to ROG) + 442422 5Q77 13:44 Eastleigh Arlington (Zg) - Wolverton Centre Sidings.
Gemini Rail have moved their re-traction package project activity from Eastleigh Works to Wolverton. The background for this change remains unclear - the shared plan has not been followed, as completion, even after revision, was not in December 2019. Indeed Class 442 is currently out of use in the emergency period.
Details of the new traction package under MBC 62958 - history for reference.
