Lets do a proper comparison between the "Pretendolino" Class 90+Mk3+DVT set and a Pendolino Class 390 set between Euston and Tamworth since the 90+Mk3+DVT is the only train that VirginTrains have that doesn't tilt (assuming tilt is enabled on the Class 221 Super Voyagers):
Euston-Tamworth: Pendolino = 1hr 2mins (based on the 17:57 EUS-GLC service)
Euston-Tamworth: "Pretendolino" = 1hr 18mins (based on the Fri 18:46)
VT schedule a 16 minute difference between Euston and Tamworth, I assume mainly because the Class 90 can only do a top speed of 110mph. You can mention the Class 91 if you like but they don't run on the WCML. You can also mention non tilting stock doing 125mph but since VirginTrains do not have any, that is irrelevant (again assuming tilt is enabled on the Class 221's)
When the "Pretendolino" set covers the EUS-BHM route (which is the only route it covers replacing a Pendolino), it is not uncommon to see it arrive late into Coventry, Birmingham International and Birmingham New Street.
Comparing a Pendolino with a C90+Mk3s is not a fair comparison.
What I'm doing is speculating whether tilt is neccessary or not, particulary as it has been implied on these pages that one can only have tilt if one puts up with minute windows, we'll forget tilting C221 Voyagers just for the sake of the argument.
What I was comparing was a non tilting EMU of the same power to weight as a Pendolino.
Rather conveniently we do in fact have just such a yardstick to compare, it's a Pendolino with inoperable tilt !
And comparing those two gives a saving of 6 to 7 minutes.
Personally I'd say that was worth having, but not if it means I'd have a good chance of spending the whole journey looking at a plastic window pillar.
Others may disagree and they're entitled to their opinion, though they should recognise that many people hold the opposite view.
I'd still like to know how many of those who don't think decent size unobstructed windows on a train are that important would be prepared to swap seats with me if I had a crap seat and they had a good one.
I bet none would.
Which, I think, speaks volumes.
That was the whole point of VHF wasn't it? Short turnaround and optimal use of stock and pathing?
The problem with short turn arounds, as with "just in time" supply chains, is that if anything goes wrong there's no slack in the system.
That's why I probably keep in far too much stock in my aerial sales business, but at least it means that if the supplier hasn't got a product in I still have. It's very rare we lose an order through lack of stock, very rare indeed.
