I think DTG should use the Class 47/8 model in a future DLC, so all of the fantastic reskins that are available for it can be used by people who never got the chance to buy the pack can use said reskins. Potentially even an unbranded Virgin Trains First Generation Pack?
It would be a great idea to have, especially if you are looking for Night Train runs in BR era. It will also be handy for reskins, such as BR Blue/Grey, Caledonian Sleeper (Only Seated and Cafe coaches).
