This thread illustrates the problem that some people treat every bit of railway as sacred - if you can't accept closing the weakest of lines (those with a Parlimentary service or very token services, e.g. Knottingley to Goole) then there's no point trying to have a rational debate about the finite budget we have.
And if your answer is "but, before we close it, we should run services there at a significantly increased frequency for a five year trial, before we can reach a decision about viability" then you are just dodging the difficult question - the numbers might go up from one man and a dog to two men and a dog but it still won't be enough to sustain a station.
By running a "Parliamentary" service you are limiting its patronage to enthusiasts doing it for the crack because it's useless for actually going anywhere, and obscuring any possibility that people might want to use it for going somewhere if there was a service to do it.
I remember getting very frustrated in the 80s trying to plan journeys from south of Manchester to north-east of it (up the WCML then across the Pennines sort of thing). The difficulty was, of course, being dumped at Piccadilly by the service from the south and then having to trog across an alien city centre wondering where Victoria was. The obvious solution according to the network map was to get off the service from the south at Stockport, get a dasher to Stalybridge, and pick up the trans-Pennine service there. Except the dasher only ran about three times a day and none of the times were any use.
These days it seems it only runs one day a week and only in one direction, so it's that much worse, while the basic problem still exists, and any other solution to it is cabbaged by the lack of capacity at Piccadilly. A "Parliamentary" service just means some TOC is putting its own good above the good of the network, not that there's no use for a proper service.
trains dawdling along to stop at places no one gets on or off really feel very very slow (the Network Express to Exeter hahahaha!)
It's not the stopping at stations that's the problem, it's the dawdling in between them - crappy low linespeeds which the train quickly reaches and then creeps along at making you feel like it'd be quicker walking, with added frustration when it drops to 15mph for a mile and a half for some slack that's been there for 20 years and nobody's done anything about it. Even worse when it's on jointed track and the slow thudding of the rail joints emphasises the low speed. Stopping for stations isn't so bad as long as the train can run fast enough between them that you do feel like it's actually making an effort, but when it never gets over 40mph or whatever you just feel like the train can't be arsed and nor can the railway as a whole.
Since people are talking about Hull - I went there once and the run was just like that - seemed to take forever, and it was in a Pacer just to make it even worse. Several stops, but far enough apart that the train could have got moving a lot faster than it did if it had been allowed to. It just felt like nobody gave a toss about the service or the people using it.
