And that then gives 30 minutes dead time doing sweet FA. If you were going to do it, you would run every 30 minutes and have empty trains or you would run WBQ to Ellesmere Port so then the train isn't empty all the time as people from Helsby, Frodsham and Runcorn all travel to Warrington.
A slight flaw in your calculations which should be looked into. Ellesmere Port as a town has 4 stations. Itself, Overpool, Little Sutton and Capenhurst. These all need to be added together to make up the towns rail usage. This would make it a fair comparison.
We could go into detail about why some of these areas have higher rail usage but in short A good few of them have universities, Some are also commuter towns for big cities and Torquay is a very touristy place. You also have, as Ianno87 says, one or two big interchanges there which are useful.
It's probably worth saying that the 3 lowest usage Merseyrail stations are in the Ellesmere Port area. Little Sutton (116k), Overpool (157k) and Capenhurst (180k). Ellesmere Port itself doesn't fair much better being the 10th least used Merseyrail station. These all have regular half hourly services to Liverpool from early until late, 7 days per week. This is much better than many stations which have more passengers and less services.
The only possible way of Eport getting an enhanced service would be a Merseyrail extension as any services towards Warrington risks causing delays between Frodsham Jct and Helsby (There are already issues sometimes with the 3tph causing congestion without adding another train into the mix). Any service towards Manchester is a non starter I think. Any paths into Manchester need to be used for some of the overcrowded local services or need to run to Chester where the proven demand is for the line.
The Eport line east to Helsby and beyond hasn't got the demand and hence has kept being cut back.
Why do people think money grows on trees. If you are going to subsidise it from your own pocket, go for it but why should everyone else have the financial burden of propping up a line which has consistently had low passenger numbers?
