I think what you're insinuating is that if it doesn't go through Bradford it isn't NPR - not the case.But then it isn't NPR. it's just TRU and no one else benefits
NPR aims for circa 30 min journey between Leeds and Manchester. If it can be achieved for less cost and integrate in with TRU then a government looking as cutting costs will see it as a preferable option. NPR via Huddersfield would still need new infrastructure Manchester - Huddersfield.
