Look, just understand. These trains are old, maintenance heavy, power hungry and clapped out. Twenty two years of 300Kph takes it out of a train. No-one else would want them for that reason.
Not only that, but where the hell would anyone have the space to store the things for 10 years (minimum) and how worthwhile would that be? There's nowhere left in the UK that's secure enough and you'd hardly want to store a train reportedly suffering from corrosion in the outside?
