When was this transferred from Network Rail ownership to the Science Museum or NRM?
Never was and may never be. It was designated to become part of the National Collection once its working life was over. That was then and its now.

This suggests that ADRC96714 will not now become part of the collection but as designated could instead become part of another accredited collection.
