Good news, though let's hope the ride quality is better than the CAF Mk 5a's Chiltern are re-introducing!

I think GWR could really do with more capacity in its high speed fleet now.  A similar order of 10 7-car units, based on either the Hitachi Class 807 (but a Tri-Mode version), or 7-car versions of these Tri-mode Class 897s, would be extremely useful to help cater for growth on both the North and South Cotswold services, and doubtless other routes, where 9-car will be overkill, but 5-cars isn't enough.  7-car services also fit nicely into the platform length profiles at most stations on those routes.

Try boarding the 10:29, 11:32, 15:31 (and others) at Oxford towards London and there's a good chance you'll be standing all the way.  Incredible given not too long ago those trains were in the hands of 3-car Turbos!
