Really been trying to keep myself busy over the bank holiday, and as such, I have churned up these!
The WSMR one is available to download, the BR Blue example with just a few finishing touches to add. As for the Network Rail and Arriva one, well. The Network Rail requires some jiggering about with the logos, and the Arriva requires the front blue section redoing.
Adding logos to the ATW one is going to be one hell of a job, so I am tempted to leave it unbranded...
All of them have custom number files as well by the way. Always handy!
