Over the Christmas holidays (which for me continue until the end of the week), I have been working to improve the selection of Great Western Railway vehicles in the pakset, adding multiple liveries to all the available types (only the 517 class is yet to complete in this respect) and adding multiple classes to all the carriages. All of the carriages have been re-created from scratch with entirely new graphics, rendered using the transparent workflow, and all have class data. We currently have a complete timeline of express passenger carriages dating back to 1893 and all types dating back to 1908.
Here is some of the progress that has been made of late:
