It's owned and operated by GBRf. Which we haven't seen in TSW yet. It's a class 66/7. Which we haven't seen in TSW yet. So it would be a bit more than just a reskin. But boy, does this look awesome:
It certainly does suit it. The standard GBRf livery looks good on the 66 as well. The EWS colours are a bit dull in comparison. For something a bit different have a look at 66720.
