I am aware I am straying into an area beyond my regular #CrossChannelRail passenger expertise, but I do not really follow the logic of this "regular freight from Barking to continental Europe" story, UK side https://www.gov.uk/government/news/landmark-deal-paves-way-for-return-of-regular-cross-channel-rail-freight

Yes, they'll fix the terminal a bit. But is running from there going to be economic? And who is going to run the trains?
