Given that the platform lengthening hasn't taken place on the Aire and Wharfe lines, so that rather than 2x3 car 331s it's going to be 1x4 car 331s for the foreseeable, I wonder if anyone who has ridden it could speculate about whether a crush-loaded 331 is better than a crush-loaded 333?
As, I understand it, they aren't high density but instead more regional seating, I'm a little intrigued as to whether (because more folk will be standing than ever) they'll actually be viewed as much of an upgrade over the existing 333s without the extra capacity promised originally?
