3229/30
Thanks to Kite159 pointing out this thread has deviated onto 373s and withdrawal of them, I'm now reading this thread and I'm shocked at just how few 373s are to be retained!
Can I seek clarification, before I update my NREA with a LOT of straight lines through the class, that these are the sets due to stay, and that the others will be going? That 8 pairs of half-sets are all that Eurostar plan to keep of the 373s?
I believe, without checking, 3209/3210 are dud for me, having had them from Marne-la-Ville Chessy to London Waterloo.
Very much behind on my Eurostar happenings, but I really need to get down there and enjoy a 373 again. It's the best part of 4 years since I last went on one!
