I feel like the cargoline type packs would be more appealing if they added to the loco roster too - I'm not asking for new models, but a few repaints would do so much to add to the variety of rolling stock on freight routes. The 08, 20, 31, 37 and 47 all exist, or at least recently have, and to have these in EWS or similar would be a relatively easy way of broadening our collections. Even some more 66 liveries would be nice to see. If you multiply those 6 classes by the licenses that DTG have acquired, there's a lot of potential there. (And yes, I know livery editor exists, and a lot of people do great work, but it can never live up to a fully developed livery, with its own timetabled services.)
I think this is a great idea, and it would be nice to see the EWS and DB scheme extended beyond countless Class 66's.
EWS/DB Cargo seems to be in the bag though. And I think DRS was covered by one of the recent gameplay packs.
