'Due to arrive on Wednesday, the train will have passed through China, Kazakhstan, Russia, Belarus, Poland, Germany, Belgium and France before crossing under the Channel and arriving in the east end of London at Barking rail freight terminal'
Russia has a different gauge, the container freight would just need lifting from one to another carriage but not sure about the train itself so mostly publicity as not practical perhaps
featured on this mornings news in actual fact, I think its kind of ambitious considering the logistics of it travelling through Russia as well but proves at least the concept is there
