I personally would add 3rd rail shoes to the Class 223 so that they could Travel from the South from places like Hastings, Eastbourne, Brighton and Portsmouth to Holyhead by using the route from Clapham Junction to Kensington Olympia and then from there on to the West Coast Main line to then travel up to Holyhead, Manchester, Edingburgh, Glasgow.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?
