Why are they bothering with HUY when they could use Doncaster Sheffield?
DSA has far better facilities, and is much closer to centres of population such as Sheffield and Leeds, as well as Doncaster, Barnsley, Rotherham etc.
They are bothering because the people of Hull, East Riding of Yorkshire and North Lincolnshire find HUY more convenient. If services with similar fares to those from DSA can be offered from HUY, then most folks from this particular region would use HUY.
Most people want convenience (ie less time/hassle) above facilities. Just as in view of my location I always prefer to use LBA due to convenience wherever possible over MAN, which has far better facilities.
