I think there should be a more British feel to this game. such as,
New bus for London (NBFL)

or some new metro like the underground 2009 stock or the s stock

or even the the london overground stock Class 378 Capitalstar (

The class 378 would be my preferred choice, as its able to be a long distance metro which can use third rail or pantograph, it's modern and would work well in cim2.
