For the WCML:
For the North Wales route - Class 223:
Diesel/Electric Hybrid, 9 car edition of the 221. Toilets improved to remove smells, 3 coaches for first class, and the blue 350/1 seating in standard class. Improved suspension and associated works to eradicate the bumping/rattling. Modified PIS to the current Pendolino format but with scrolling text and the new automated announcements.
It certainly works well for the Swiss:I like that! How about a hauled version for 'land cruise' trains around the Highlands in the summer?
