I think that a class 805/807 would be a good add on because of the recent adding of the WCML London Euston to Milton Keynes. It could add a new layer on time table mode as well as some variation from just pendolino, class 350 and class 66. If there was more of the WCML, it could layer on to that. It could also be quite easy to maybe reskin the class 801 into the units of corse removing the diesel from the 807.
