Commuters don't get turned away from class 800s (and before that slam-door HSTs) do they? So why should they be turned away from a Swansea to Manchester service? I am not saying that the long-distance services should be reserved for long-distance passengers. I'm meerly saying that Swansea-Manchester (along with other routes on the Wales & Borders franchise) is important for long-distance passengers and that the trains should be designed to be attractive to that market. That isn't just about the position of the doors (and, as noted above, I'm open to a compromise door layout). The width of the doors (almost double a 175 I believe, though I don't have the figures) is the bigger problem because it robs space from everything else, things that do matter to everyone not just me.
The trains need to be designed to be attractive to as many markets as possible as those that they will serve. Whilst it is true there is a (relatively small) InterCity market they serve, they also have a much bigger role in providing regional services out of big cities, often for commuters. You can't ignore this role just to keep the small amount of people making long distance runs happy - and in any case, there is little evidence yet (other then a low amount of toilets) that these units won't be suitable for InterCity journeys. They will be clean and new, the Swansea - Manchester sets will have first class, all will have sure conditioning and catering trollies, and for the vast majority of the people making long distances, that will be sufficient. They will also have a layout that will be more suitable for the shorter journeys that many passengers make, and which will have a very positive effect on dwell times
I note that commuters are mentioned. At the southern end of The Marches, surely it would be desirable to have a new station at Caerleon and have that - along with Cwmbran, Pontypool/NewInn served by a local stopper to/from Abergavenny - where a new bay platform could easily be created? By shifting this local traffic going to/from Newport, Cardiff East Parkway and Cardiff Central, we could speed up the long distance services - with passengers transferring at Abergavenny for places further north? (I note that Pontypool/New Inn is to get a new car park with direct access from the A4042. This would be the nearest rail station to Use and is bound to attract more commuters. All the more reason therefore to serve these people with a local service rather than try and get the long distance express trains to perform the function of a local stopper as well?
There's been talk for years about a station at Caerleon, and an Abergavenny shuttle to serve it. That said, under the new timetable there will already be at least 2 trains per hour over that section anyway, and with the improved acceleration the 197s should offer it might but even be necessary to add an extra service.
Finally, I must mention fares - even though this is not the fares section but it is highly relevant. The fares between south Wales & places north of Crewe are apparently set by Cross Country as it is deemed a so called ‘Inter City’ route. So, if somebody wishes to travel from say Cardiff to Edinburgh tomorrow - the fare one way = £192.60. (Carlisle is £143.50). Craigybagel says that very few passengers are aware of split ticketing. I know of somebody in Cardiff who wanted to visit a relative in Carlisle. This family of 3 put in for a fare and up came the sky high fare charged by Cross Country. These people knew nothing of split ticketing and simply chose to drive - hence we have business lost to TfW & what is not Avanti due to this ridiculous fares policy. I wonder how many staff working The Marches have found through tickets where those who did not know better are paying these sky high fares? I also wonder if staff at stations are telling customers the cheapest way of doing such journeys?
Retail staff and conductors aren't supposed to tell passengers about split fares. If the customer asks for it, then it has to be issued as a split, but it's down to the customer to find the split first. This is a more fair system as not all staff know the best splits, and other then trial and error on the ticket machine or by using their own phone to access a third party website they have no way of finding the best splits themselves.
As far as I can tell, the best unit for timekeeping on the 18:30 from Manchester is a 150, at least as far as Shrewsbury. For those that don't know, this stops all stations south of Crewe to Cardiff. 175s struggle to keep time although they will make it up as the schedule is very slack south of Hereford.
150s will easily match if not beat the acceleration of a 175 up to about 70 mph, plus the door layout makes dwell times a lot quicker. It will struggle for timing between Wilmslow and Crewe though as that's a long run at 75mph Vs 100mph for a 175.
