The GWR green brand was still developed by First Group, even if it doesn’t have their name on it - it’s their branding identity which they developed, even if it will pass on to the DfT after they hand the control over to them. Same with Avanti West Coast, even if it doesn’t say First Group and Trenitalia on it, unlike with Trenitalia which was on c2c. Same with all of Govia’s various brands, and National Express’ various different liveries, such as “one”, before they changed them and put National Express on them. Just like Essex Bus is a First Bus brand identity, even if it doesn’t say First Bus on it.
