There aren’t enough 800 9 cars for North Cotswolds, the 800 9 cars were built for the core table 125 routes. 802s with larger fuel tanks are needed for Cotsworlds and West of England’s where the majority of the route is on diesel.
The nine-car 800s are perfectly capable of operating Cotswold Line diagrams and do it all the time right now - 802s are very much the exception under current arrangements and we have yet to see how things will eventually shape up under diagrams for the new timetable.
That some of the nine-car 802s were ordered for peak Cotswold workings was because, as Clarence Yard has explained previously, GWR had identified a shortfall in the size of the 800 fleet and managed to persuade the DfT that it needed more stock to fill that gap, alongside providing the new trains for West Country services.
Except, the Paddington to Penzance route is not exactly bargain basement. If anything it's a premium fare, there are plenty of people I k ow in Plymouth who cannot afford to use the train. We are not talking about budget airline priced tickets here....
Except what? You were the one complaining about the journey times comparisons with France. There are trains there with similar or longer journey times than London-Cornwall with zero catering, never mind a trolley or Pullman restaurant.
GWR is currently offering advances on a series of departures from Paddington to Penzance and in the other direction on Saturdays July 13, 20 and 27 for all of £25. Hardly a premium fare in my book. I doubt FlyBe will be undercutting that price to Newquay.
If GWR was proposing a Ouigo type service to Penzance, you might have something to complain about. Though by the sound of it, First Group's East Coast open-access services will certainly draw some ideas from Ouigo, such as not having first class.
But perfectly feasible for everything coming on and off Laira and north pole be 9 cars. That would be a start, added to one 9 car departure from long rock a much better balance would be achieved than the situation now . There are intelligent people out there who could 're jig the unit diagramming to get rid of for example 9 cars to Hereford off peak which surely should be a pair of 5 cars splitting and joining at oxford to give one example.
I've already said that it looks like a nailed-on certainty that the first out and back London-Hereford off-peak working on weekdays will be a five-car from the timetable change anyway. The second one will most likely remain a nine-car, due to the times it calls at Oxford, Reading and Slough on the way back into London - ie in the afternoon peak.
No one is going to start building in performance risks at that time of day by adopting a method of working at Oxford that has performance risk written all over it.
