I disagree with those that suggest celebrating (for lack of a better word) the upcoming end of an era is pointless. Surely, if that were so, neither FGW or EMT would have gone to the trouble of organising similar things. Granted, EMT went one better and organised a railtour of sorts to Scarborough with them, and both operators continued using their Valentas for some time after (EMT for longer than FGW did), but at least those of us who like HSTs to sound like HSTs had the opportunity to mark the end of Valentas.
Yes, it would be much more of an issue if it was class members getting scrapped, I don't think anyone would disagree. Nevertheless, surely marking the end of an 34-year long era is worthy. It will be the end of Valentas in a rail application across the country, not just the ECML. Well, until the opportunity arises for the 125 Group to put what they've got into use of course.
Yes, MTU has extended the life of the majority of the class, VP185 doing the same to a lesser extent on the MML. For which we should be thankful. Just as much so for the life-extending work potentially to happen in the near future on the HST trailer stock (I don't hear of it being confirmed, hence the key word "potentially"), which will keep the fleet as a whole running for years to come and scrapping hopefully a long way away!
I got into HSTs mainly because of the noise they made and they show they put on. If it had been MTUs back in 2003, I seriously doubt I'd have bothered. Same for if I'd been in the same boat but at Kings Cross and just 91s around, I seriously doubt I'd have bothered, I don't find 91s all that interesting. Even so, I still travel on HSTs, MTU or not, IC70 seats or not. I much prefer travel on a HST than a DMU, nothing quite as thrilling as travelling at 125mph on this side of London (395s, however, on the East side are quite enjoyable).
