But who are the majority of passengers? ...
In the case of GTR north of London and in the context of my post, it is easier to first identify the minority, who as I said above are those who don't want their travel arrangements to change. Given the need for change, I suspect that there is little consideration for all other passenger's needs so all those other passengers are in the majority.
... Peak? Well we know from your posts you have nothing but contempt for them because of their subsidised season tickets. You have stated in previous posts that treating the captive market badly is acceptable as they have no alternative. Unfortunately this fact is true. Making the journey uncomfortable will not lose many of these. Pricing them off if the only solution.
You should read what I actually say about season ticket pricing. My irritation is that despite most of the annual season tickets being valid for Anytime travel over 480 journeys per year, there are still many who complain that they are paying £3000, £5000 etc., (insert whatever fare it is) per year, when they are in fact paying below off-peak ticket prices, yet they still insist that they are essential for the railway's commercial functioning.
In reality, much of the infrastructure and rolling stock investment is there purely to provide services for two hours am and another two pm, and that is for passengers who pay less than a leisure traveller who voluntarily restricts their access to off-peak services when there is normally plenty of underused capacity. The conclusion therefore is that season ticket travel is heavily subsidised, which is fine by me, but those benefitting from the subsidy should stop whingeing and be grateful that other passengers/public funds are carrying the cost of their travel. In effect, they are in a captive market because they are heavily subsidised.
... Off-Peak? Well these passengers in normal service get a seat most of the time. Even on great northern overcrowding will be resolved by the fact trains are 8 coaches. We may see an increase in passengers as a result. However Thameslink also wants to attract Cambridge- Gatwick off peak travellers. They can drive - congestion isn’t horrendous off peak. They can go by coach. Comfortable environment compared to the train. Or use Thameslink. The spartan interior won’t attrack off-peak travellers.
Cross-London travel from Herts. to Gatwick, (and the reverse from Surrey/Sussex to Luton) has been available via the MML/BML for almost thirty years. It has continued to grow (including since the introduction of class700 stock) and for many is a viable means of trouble-free travel to and from holiday airports. The service runs through the night (one of the few in the south-east) but the M1/M25/M23 either self-drive or coach are alternatives so travellers can make their choice. I would put money on there being a sizeable trade in passengers travelling down the ECML and Cambridge lines within a year of the full service starting. The fact that some might prefer softer seats won't make that much difference to the volume of travellers. Being able to get on a spacious train with more luggage than can be taken on a flight and no requirement to change will ensure that for most, plusses and minuses are weighed up.
The train is designed of crush loading of peak passengers with no thought of comfort to attract more off-peak. Would a decent seat really be too much to ask? So who is the majority? The captive market of subsidised season ticket holders you seem to dislike so much? If it is they have still got it wrong and should have gone for longitudinal seats?
Do you work for GTR?
The train is specified to do a variety of jobs. It would seem that commuters get the preferential treatment because of the absolute need to deliver peak capacity, (see above re. season ticket holders being the cause of much railway investment). I am not a commuter (it's over 30 years since I did any rail commuting, - over 40 years in the London area) but the investment cannot just fail to meet
that level of demand. Now as I have said, public funds for rail investment are of necessity limited which means that it isn't possible to have 'commuter rolling stock' that runs for just four hours per day to be put away in sidings and replaced with more luxurious trains between the peaks. Most passengers understand this and is does not discourage the majority of leisure travellers from using the commuter friendly trains in the off-peak. If some more extreme predictions of become reality, it may indeed be necessary to have some longitudonal seating put in rather that do nothing for decades whilst politicians haggle over the budget for additional lines. The alternative for commuters is that they won't be able to board trains at all, - just like on Thameslink 10 years ago. After all, The current Thameslink enhancements have taken nearly 30 years to materialise, Crossrail was originally identified as a need over 50 years ago.
Oh and by the way, I don't work for anybody, nor have I ever had any employment in any part of the railway industry let alone GTR.
