Decided to do an Express Aventra with new CrossCountry branding...

The logo represents the major corridors for XC (Edinburgh, Bournemouth, Cornwall and Manchester) meeting in Birmingham with the arrows of the logo pointing there also.

In other words, I got a bit bored

Going off assumptions...

Class number? It would be bi-mode so probably 721 or 74X
No of seats? Assuming luggage racks etc I calculate 364 standard and 56 first (420 overall), more than double a 4-car Voyager set
