This is true ! My calling that corridor "The Little North Western" is a simplification, although I feel justified in calling it that as Skipton - Wennington comprises the lions share of the old Little North Western (and the current day route).
The route is interesting and scenic, if a little slow. However it will be a lot more useful with later departures.
Given that there are very few cross-country routes between Preston and the Scottish central belt, the Bentham line is very useful for getting to Leeds or indeed parts of the north-east from North Lancashire and South Cumbria, and certainly quicker than going via Manchester.
