And I doubt Tesco are fully utilising 8 trains a day - I suspect you're looking at half a dozen containers a day - so you're losing fewer than 50 HGV trips - which are tending to go from a port to either DIRFT or Mossend.
It would be helpful if you looked at the available information before making such comments.
All 8 trains are dedicated to Tesco for distribution from primary to secondary distribution centres.
One pair runs between DIRFT and Mossend daily with 38 Tesco containers on each train.
One pair runs between DIRFT and Tilbury with 40 Tesco containers on each train.
One pair runs between DIRFT and South Wales with 30 Tesco containers on each train.
The final pair runs between Central Scotland and Inverness with 22 Tesco containers on each train.
That is a total of 260 containers daily. All trains backload with goods from manufacturers to DIRFT.
Additionally Tesco buy space on other trains from the ports to DIRFT and on other trains from DIRFT to Scotland run by Russell or Malcolm as required.
