We have trolleys on the SWT Exeter Waterloo service (2 hours 45* min with stops at every farmyard) and they work perfectly.
*Axminster to Waterloo time
As a frequent user of the line as well, I'm actually going to in part disagree with you. On the majority of the westbound services I've used, the trolley - if it makes it through - always comes off at Axminster. Fine if your going as far as there, but what if your getting on there or stations westwards? Some of them have made it through, others have not been able to, and some just didn't turn up at all - the peril of a Trolley service over say a Mini Buffet. Even coming out of Waterloo, when the service is busy they suffer again because they become trapped - one peak service I used last summer the trolley was stuck behind FC, and wouldn't have been able to move forward until at least Basingstoke (where I got off) or Andover. Sometimes it works, others it doesn't.
One thing that's changed these days is the amount of tech being carried. If I've got a couple of laptops and a tablet on me, I would rather a trolley and may well not bother at all if there isn't one, as I won't be leaving them unattended (and indeed would get in trouble if my work laptop was nicked in such circumstances).
Possibly, possibly not. I have used HSTs plenty of times and either hidden my phone when on charge or put it in my bag or taken it with me. But even on the HSTs I was on last Saturday, people to my side or in front of me we're happy to leave their laptops or IPads out while popping off to the buffet car.
Wasn't the trolley abandoned on HSTs because it couldn't get through the train and also that the trolley's design when combined with HSTs actually caused incidents and accidents to staff?
Can't see it being any different with IEP / SET.
Indeed, the cancellation of that trail led to the creation of the Mini Buffets - despite having removed a toilet from nearly each Mk3 to become a stores cupboard. Rather a shame we can't at least have a Mini Buffet on the IEPs, even a kitchen for First and Mini Buffet for standard would be a much better idea than this ridiculous Kitchen for FC, and potential trolley for standard. And how does the trolley set up work on 2 IEPs coupled together? 2 lots of trolley staff in Each IEP seems a rather wasteful way to do things to me, but then again we seem to have become obsessed with Spliting and joining again. I'm also interested to understand how they will send this trolley through a very busy or packed IEP... And I wouldn't like to be the one having to haul a trolley up and down and over all those internal ramps over each engine in each car of each SET.
As to the reasons why VTEC seem to have got their way - I have a strong feeling that Politics has come into this - VT as we know like to get their way and will do so at almost any cost, they say their unhappy that their IEP doesn't have an on board shop, they complain. First - going out of their way to continue running the franchise for another 4 years faces up to as a do as your told DfT in another acceptance to keep the franchise. I would bet too that these extra West Country (Any chances of Pullman Dining going?), while being privately funded, will also be "discounted" to keep Hitachi's production line open for a little longer... Cynical maybe, but just like the garlic in my Kiev tonight, something seems to be smelling pretty obvious.
Of course any fictional (and I'm afraid having seen nothing of this survey am going to believe that it is a piece of fiction) doesn't give you the option of the standard of catering you get either. Do you want a Express Cafe with freshly ground coffee, and some time to chose what you want from the counter... A Travelling Chef option, and or Express Cafe and Pullman Dining for both first and standard. Or do you want a mini buffet allowing some hot food to be grilled / cooked, freshly ground coffee, giving some of the current service provisions or just a trolley with a limited range of options that may get through the train if not full, may contain some of the options or may have run out. Instead, and thanks to the DfTs myrad of restrictional options, you either get Trolley for all, or Kitchen for First and Trolley for standard with optional microwaved food. Backward step? Of course. But what does Marsham Street know about train travel comfort?
