Pathing issues - The Leeds stopping train goes just a few minutes after an express train and coming from Leeds the Liverpool to Scarborough service will catch it up ordinarily (it already does catch it up at Micklefield).
That's not true; today there's 10 minutes between the respective arrivals from Leeds into York and 19 minutes between the respective departures from York towards Leeds.
Adding a call at Church Fenton would not add any more than 5 minutes at the most.
Today there are 4 trains per hour (1 XC, 1 Northern, 2 TPE); on a normal Saturday there would be 7 trains per hour (1 XC, 2 Northern, 4 TPE).
Clearly, there is sufficient capacity to serve all intermediate stations.
At the moment, the Leeds stopping train could leave York about three minutes earlier, however, this service runs on the back of an express train (Newcastle to Manchester Airport which isn’t running at the moment). ....
OK so let me get this straight: there are fewer trains operating between York and Leeds, one of those trains would normally call at Church Fenton. People are calling for the Church Fenton call to be reinstated. You are rejecting this on the basis that, if more express trains were running, there would not be sufficient capacity for an additional call at Church Fenton on the remaining stopping service.
I don't understand your logic; if all trains were running there would not be a problem. As there are huge gaps in the service at the current time, there clearly is spare capacity for all intermediate stations to be served during the current period.
Northern have decided to stop the service of trains from Church Fenton to Leeds. Passengers are advised to travel via York, an extra 20 miles with an increase in fare of about £10,...
Do you have documented evidence of Northern stating passengers are required to pay an additional £10? If so, you should consider writing to the ORR, DfT, Transport Focus and MP about this matter.
My understanding is that ticket acceptance should be in place.
