Chester will lose its direct connection to the Manchester Airport which for the people of the N Wales coast will be a big loss.Would it? Is there substantial commuting from west of Chester to Warrington? (The Northern Chester-Vic service would continue running via Warrington, wouldn't it?)
Where can one reach by changing at Warrington that one can't by changing at Liverpool, Chester, Crewe or Manchester?
(CLC local stations are not major destinations and the walk across Warrington is inconvenient)
Helsby and Frodsham plus runcorn East will have no services to Manchester or Warrington BQ and Frodsham / Runcorn east are quite busy for commuters.
Unless the Leeds services are made to stop at all stations but it then loses its paths and Chester loses its frequency over the route.
On the second point a lot of people going to Scotland travel to WBQ for the connections and that would be a loss as the Leeds services are not very frequent. Plus Northern quite often cancel the Leeds services for some reason and if that's the only services via WBQ it could be disastrous if TFW don't take the customers as this is the method now.
It would be the loss of a long established route that tfw want to keep and much needed revenue for them.
Then there's the huge amount of road learning for Chester/n Wales coast depots, that's another expense that tfw woukd need compensating for.
