Cover, but only if your near t'hills.
It would appear that the West Yorkshire force is surrounded by NPAS bases, where as places like Scotland have only one airframe to cover the whole of Scotland? A bit like the Wales setup I believe. Stand corrected if I'm wrong.
Now I wonder why that is?
Is it because West Yorkshire are supposed to be in control of this train set or they need air cover more than others?
Why do the Met need 145's compared to other units?
