I've proposed a Cringleford station quite a few times, it'd be a great location for a modest amount of new housebuilding and for serving the whole western half of outer Norwich which is currently poorly served by any mode apart from driving, especially for journeys to Peterborough, Cambridge and London.
Unfortunately the level crossings and any increase in use of the local roads are a problem. Along with the local nimbies. It appears to have never gained any traction with the district council or MP though so it's probably going nowhere. One Norfolk County Council report suggested a new station in Thetford would be a higher priority.
